# Contributing to Jekyll
Hi there! Interested in contributing to Jekyll? We'd love your help. Jekyll is an open source project, built one contribution at a time by users like you.
## Where to get help or report a problem
* If you have a question about using Jekyll, start a discussion on [Jekyll Talk](https://talk.jekyllrb.com).
* If you think you've found a bug within a Jekyll plugin, open an issue in that plugin's repository.
* If you think you've found a bug within Jekyll itself, [open an issue](https://github.com/jekyll/jekyll/issues/new).
* More resources are listed on our [Help page](https://jekyllrb.com/help/).
## Ways to contribute
Whether you're a developer, a designer, or just a Jekyll devotee, there are lots of ways to contribute. Here's a few ideas:
* [Install Jekyll on your computer](https://jekyllrb.com/docs/installation/) and kick the tires. Does it work? Does it do what you'd expect? If not, [open an issue](https://github.com/jekyll/jekyll/issues/new) and let us know.
* Comment on some of the project's [open issues](https://github.com/jekyll/jekyll/issues). Have you experienced the same problem? Know a work around? Do you have a suggestion for how the feature could be better?
* Read through [the documentation](https://jekyllrb.com/docs/home/), and click the "improve this page" button, any time you see something confusing, or have a suggestion for something that could be improved.
* Browse through [the Jekyll discussion forum](https://talk.jekyllrb.com/), and lend a hand answering questions. There's a good chance you've already experienced what another user is experiencing.
* Find [an open issue](https://github.com/jekyll/jekyll/issues) (especially [those labeled `help-wanted`](https://github.com/jekyll/jekyll/issues?q=is%3Aopen+is%3Aissue+label%3Ahelp-wanted)), and submit a proposed fix. If it's your first pull request, we promise we won't bite, and are glad to answer any questions.
* Help evaluate [open pull requests](https://github.com/jekyll/jekyll/pulls), by testing the changes locally and reviewing what's proposed.
## Submitting a pull request
### Pull requests generally
* The smaller the proposed change, the better. If you'd like to propose two unrelated changes, submit two pull requests.
* The more information, the better. Make judicious use of the pull request body. Describe what changes were made, why you made them, and what impact they will have for users.
* Pull requests are easy and fun. If this is your first pull request, it may help to [understand GitHub Flow](https://guides.github.com/introduction/flow/).
* If you're submitting a code contribution, be sure to read the [code contributions](#code-contributions) section below.
### Submitting a pull request via github.com
Many small changes can be made entirely through the github.com web interface.
1. Navigate to the file within [`jekyll/jekyll`](https://github.com/jekyll/jekyll) that you'd like to edit.
2. Click the pencil icon in the top right corner to edit the file
3. Make your proposed changes
4. Click "Propose file change"
5. Click "Create pull request"
6. Add a descriptive title and detailed description for your proposed change. The more information the better.
7. Click "Create pull request"
That's it! You'll be automatically subscribed to receive updates as others review your proposed change and provide feedback.
### Submitting a pull request via Git command line
1. Fork the project by clicking "Fork" in the top right corner of [`jekyll/jekyll`](https://github.com/jekyll/jekyll).
2. Clone the repository locally `git clone https://github.com/<you-username>/jekyll`.
3. Create a new, descriptively named branch to contain your change ( `git checkout -b my-awesome-feature` ).
4. Hack away, add tests. Not necessarily in that order.
5. Make sure everything still passes by running `script/cibuild` (see [the tests section](#running-tests-locally) below)
6. Push the branch up ( `git push origin my-awesome-feature` ).
7. Create a pull request by visiting `https://github.com/<your-username>/jekyll` and following the instructions at the top of the screen.
## Proposing updates to the documentation
We want the Jekyll documentation to be the best it can be. We've open-sourced our docs and we welcome any pull requests if you find it lacking.
### How to submit changes
You can find the documentation for jekyllrb.com in the [docs](https://github.com/jekyll/jekyll/tree/master/docs) directory. See the section above, [submitting a pull request](#submitting-a-pull-request) for information on how to propose a change.
One gotcha, all pull requests should be directed at the `master` branch (the default branch).
### Updating FontAwesome iconset for jekyllrb.com
We use a custom version of FontAwesome which contains just the icons we use.
If you ever need to update our documentation with an icon that is not already available in our custom iconset, you'll have to regenerate the iconset using Icomoon's Generator:
1. Go to <https://icomoon.io/app/>.
2. Click `Import Icons` on the top-horizontal-bar and upload the existing `<jekyll>/docs/icomoon-selection.json`.
3. Click `Add Icons from Library..` further down on the page, and add 'Font Awesome'.
4. Select the required icon(s) from the Library (make sure its the 'FontAwesome' library instead of 'IcoMoon-Free' library).
5. Click `Generate Font` on the bottom-horizontal-bar.
6. Inspect the included icons and proceed by clicking `Download`.
7. Extract the font files and adapt the CSS to the paths we use in Jekyll:
- Copy the entire `fonts` directory over and overwrite existing ones at `<jekyll>/docs/`.
- Copy the contents of `selection.json` and overwrite existing content inside `<jekyll>/docs/icomoon-selection.json`.
- Copy the entire `@font-face {}` declaration and only the **new-icon(s)' css declarations** further below, to update the
`<jekyll>/docs/_sass/_font-awesome.scss` sass partial.
- Fix paths in the `@font-face {}` declaration by adding `../` before `fonts/FontAwesome.*` like so:
`('../fonts/Fontawesome.woff?9h6hxj')`.
### Adding plugins
If you want to add your plugin to the [list of plugins](https://jekyllrb.com/docs/plugins/#available-plugins), please submit a pull request modifying the [plugins page source file](https://github.com/jekyll/jekyll/blob/master/docs/_docs/plugins.md) by adding a link to your plugin under the proper subheading depending upon its type.
## Code Contributions
Interesting in submitting a pull request? Awesome. Read on. There's a few common gotchas that we'd love to help you avoid.
### Tests and documentation
Any time you propose a code change, you should also include updates to the documentation and tests within the same pull request.
#### Documentation
If your contribution changes any Jekyll behavior, make sure to update the documentation. Documentation lives in the `docs/_docs` folder (spoiler alert: it's a Jekyll site!). If the docs are missing information, please feel free to add it in. Great docs make a great project. Include changes to the documentation within your pull request, and once merged, `jekyllrb.com` will be updated.
#### Tests
* If you're creating a small fix or patch to an existing feature, a simple test is more than enough. You can usually copy/paste from an existing example in the `tests` folder, but if you need you can find out about our tests suites [Shoulda](https://github.com/thoughtbot/shoulda/tree/master) and [RSpec-Mocks](https://github.com/rspec/rspec-mocks).
* If it's a brand new feature, create a new [Cucumber](https://github.com/cucumber/cucumber/) feature, reusing existing steps where appropriate.
### Code contributions generally
* Jekyll uses the [Rubocop](https://github.com/bbatsov/rubocop) static analyzer to ensure that contributions follow the [GitHub Ruby Styleguide](https://github.com/styleguide/ruby). Please check your code using `script/fmt` and resolve any errors before pushing your branch.
* Don't bump the Gem version in your pull request (if you don't know what that means, you probably didn't).
## Running tests locally
### Test Dependencies
To run the test suite and build the gem you'll need to install Jekyll's dependencies by running the following command:
<pre class="highlight"><code>$ script/bootstrap</code></pre>
Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
<pre class="highlight"><code>$ script/cibuild</code></pre>
If you are only updating a file in `test/`, you can use the command:
<pre class="highlight"><code>$ script/test test/blah_test.rb</code></pre>
If you are only updating a `.feature` file, you can use the command:
<pre class="highlight"><code>$ script/cucumber features/blah.feature</code></pre>
Both `script/test` and `script/cucumber` can be run without arguments to
run its entire respective suite.
## A thank you
Thanks! Hacking on Jekyll should be fun. If you find any of this hard to figure out, let us know so we can improve our process or documentation!

<!--
Hi! Thanks for considering to file a bug with Jekyll. Please take the time to
answer the basic questions. You can convert `[ ]` into `[x]` to check boxes (or submit
and check.) If there is no need for certain fields like output and redirection, please delete
those headers before submitting. We know not all tickets require those steps.
Otherwise, please try to be as detailed as possible.
If you are unsure this is a bug in Jekyll, or this is a bug caused
by a plugin that isn't directly related to Jekyll, or if this is just
a generic usage question, please consider asking your question at
https://talk.jekyllrb.com where non-bug questions go.
Please make sure to mention an affinity team whose responsibilities
most closely align with your issue.
Thanks!
-->
- [ ] I believe this to be a bug, not a question about using Jekyll.
- [ ] I updated to the latest Jekyll (or) if on GitHub Pages to the latest `github-pages`
- [ ] I ran `jekyll doctor` to check my configuration
- [ ] I read the CONTRIBUTION file at https://jekyllrb.com/docs/contributing/
- [ ] This is a feature request.
---
- [ ] I am on (or have tested on) ***macOS*** 10+
- [ ] I am on (or have tested on) ***Debian/Ubuntu*** GNU/Linux
- [ ] I am on (or have tested on) ***Fedora*** GNU/Linux
- [ ] I am on (or have tested on) ***Arch*** GNU/Linux
- [ ] I am on (or have tested on) ***Other*** GNU/Linux
- [ ] I am on (or have tested on) ***Windows*** 10+
<!--
Other GNU/Linux includes Scientific GNU/Linux, CentOS GNU/Linux, and others.
If you are on a minor sub-distro (such as ElementaryOS which does not diverge from
Ubuntu much, please check the parent distro. Kubuntu, Edubuntu, Lubuntu should
also be flagged as Ubuntu as their packages come from upstream Ubuntu.
-->
---
- [ ] I was trying to install.
- [ ] There is a broken Plugin API.
- [ ] I had an error on GitHub Pages, and I have reproduced it locally.
- [ ] I had an error on GitHub Pages, and GitHub Support said it was a Jekyll Bug.
- [ ] I had an error on GitHub Pages and I did not test it locally.
- [ ] I was trying to build.
- [ ] It was another bug.
## My Reproduction Steps
<!--
If this error occured on GitHub Pages, please try to provide us with logs,
and look at them yourself, to determine if this is an actual Jekyll bug. In
the event you are unsure, file a ticket, however, when you do please provide
the logs (strip them of personal information.)
If you have trouble finding your logs, please email support@github.com and
they will happily help you. If you cannot find logs, please try your best to
replicate it locally because we cannot fix a problem if we do not know
exactly what caused it, or within a relatively close distance.
-->
<!--
Insert the steps you took to for this problem to exist. Such as the
directories you created and, the full command you ran, and include any
plugins you have installed, this is very important.
If your steps are complicated, you can also submit a GitHub
repository (please no zips, they will be removed and rejected by maintainers,)
and just supply a command for us to reproduce it ourselves.
-->
## The Output I Wanted
<!--
Insert the output from the command. Alter it as little as you can.
The minimum should be personal information. Though we normally don't log
anything like that so there should be no need to alter it.
-->
/cc include any Jekyll affinity teams here (see https://teams.jekyllrb.com/ for more info)

Jekyll is a simple, blog-aware, static site generator perfect for personal, project, or organization sites. Think of it like a file-based CMS, without all the complexity. Jekyll takes your content, renders Markdown and Liquid templates, and spits out a complete, static website ready to be served by Apache, Nginx or another web server. Jekyll is the engine behind [GitHub Pages](https://pages.github.com), which you can use to host sites right from your GitHub repositories.
## Philosophy
Jekyll does what you tell it to do — no more, no less. It doesn't try to outsmart users by making bold assumptions, nor does it burden them with needless complexity and configuration. Put simply, Jekyll gets out of your way and allows you to concentrate on what truly matters: your content.
## Having trouble with OS X/macOS?
See: https://jekyllrb.com/docs/troubleshooting/
## Getting Started
* [Install](https://jekyllrb.com/docs/installation/) the gem
* Read up about its [Usage](https://jekyllrb.com/docs/usage/) and [Configuration](https://jekyllrb.com/docs/configuration/)
* Take a gander at some existing [Sites](https://wiki.github.com/jekyll/jekyll/sites)
* [Fork](https://github.com/jekyll/jekyll/fork) and [Contribute](https://jekyllrb.com/docs/contributing/) your own modifications
* Have questions? Check out our official forum community [Jekyll Talk](https://talk.jekyllrb.com/) or [`#jekyll` on irc.freenode.net](https://botbot.me/freenode/jekyll/)
## Code of Conduct
In order to have a more open and welcoming community, Jekyll adheres to a
[code of conduct](CONDUCT.markdown) adapted from the Ruby on Rails code of
conduct.
Please adhere to this code of conduct in any interactions you have in the
Jekyll community. It is strictly enforced on all official Jekyll
repositories, websites, and resources. If you encounter someone violating
these terms, please let a maintainer ([@parkr](https://github.com/parkr), [@envygeeks](https://github.com/envygeeks), [@mattr-](https://github.com/mattr-), or [@alfredxing](https://github.com/alfredxing)) know and we will address it as soon as possible.
## Diving In
* [Migrate](http://import.jekyllrb.com/docs/home/) from your previous system
* Learn how the [YAML Front Matter](https://jekyllrb.com/docs/frontmatter/) works
* Put information on your site with [Variables](https://jekyllrb.com/docs/variables/)
* Customize the [Permalinks](https://jekyllrb.com/docs/permalinks/) your posts are generated with
* Use the built-in [Liquid Extensions](https://jekyllrb.com/docs/templates/) to make your life easier
* Use custom [Plugins](https://jekyllrb.com/docs/plugins/) to generate content specific to your site

h1. Jekyll
By Tom Preston-Werner, Nick Quaranto, and many awesome contributors!
Jekyll is a simple, blog aware, static site generator. It takes a template directory (representing the raw form of a website), runs it through Textile or Markdown and Liquid converters, and spits out a complete, static website suitable for serving with Apache or your favorite web server. This is also the engine behind "GitHub Pages":http://pages.github.com, which you can use to host your project's page or blog right here from GitHub.
h2. Getting Started
* "Install":http://wiki.github.com/mojombo/jekyll/install the gem
* Read up about its "Usage":http://wiki.github.com/mojombo/jekyll/usage and "Configuration":http://wiki.github.com/mojombo/jekyll/configuration
* Take a gander at some existing "Sites":http://wiki.github.com/mojombo/jekyll/sites
* Fork and "Contribute":http://wiki.github.com/mojombo/jekyll/contribute your own modifications
* Have questions? Post them on the "Mailing List":http://groups.google.com/group/jekyll-rb
h2. Diving In
* "Migrate":http://wiki.github.com/mojombo/jekyll/blog-migrations from your previous system
* Learn how the "YAML Front Matter":http://wiki.github.com/mojombo/jekyll/yaml-front-matter works
* Put information on your site with "Template Data":http://wiki.github.com/mojombo/jekyll/template-data
* Customize the "Permalinks":http://wiki.github.com/mojombo/jekyll/permalinks your posts are generated with
* Use the built-in "Liquid Extensions":http://wiki.github.com/mojombo/jekyll/liquid-extensions to make your life easier
h2. Runtime Dependencies
* RedCloth: Textile support (Ruby)
* Liquid: Templating system (Ruby)
* Classifier: Generating related posts (Ruby)
* Maruku: Default markdown engine (Ruby)
* Directory Watcher: Auto-regeneration of sites (Ruby)
* Pygments: Syntax highlighting (Python)
h2. Developer Dependencies

== Preface
Jekyll was born out the desire to create a blog engine that would make it
possible to write posts in my local text editor, version those posts with Git,
and keep up with my desire to tweak the styles and layout of my site.
In other words, I wanted something that fit into my existing software
development workflow and toolchain. Jekyll handles not only this case, but a
wide variety of other situations that call for static site generation based on
converted content and layout templates.
At its core, Jekyll is a text transformation engine. The concept behind the
system is this: you give it text written in your favorite markup language, be
that Markdown, Textile, or just plain HTML, and it churns that through a
layout or series of layout files. Throughout that process you can tweak how
you want the site URLs to look, what data gets displayed on the layout and
much more.
If you're looking for a simple, yet powerful solution to your blogging or
static site needs, Jekyll may be just what you've been looking for.
=== What this book covers
_Chapter 1, Quick Start_ covers installation, introduces the Jekyll command
line interface, and runs through a quick example demonstrating the site
generator, post generator and how to convert your Jekyll site into a static
site.
_Chapter 2, Directory Layout_ covers the various files and directories that
comprise a Jekyll site.
_Chapter 3, Tags and Filters_
_Chapter X, Deploying your Jekyll Site_
_Chapter X, Customizing Jekyll with Plugins_
_Chapter X, Migrating to Jekyll from your Existing Blog_
_Chapter X, Configuration Reference_

== Chapter 1: Quick Start
This chapter is designed to get you up and running with Jekyll as quickly as
possible.
=== Installation
The best way to install Jekyll is via RubyGems:
----
gem install jekyll
----
This is all you need in order to get started with a basic Jekyll site. Some
options require additional packages to be installed.
If you encounter errors during gem installation, you may need to install the
header files for compiling extension modules for ruby 1.8:
.Debian
----
sudo apt-get install ruby1.8-dev
----
.Red Hat / CentOS / Fedora systems
----
sudo yum install ruby-devel
----
.NearlyFreeSpeech
----
RB_USER_INSTALL=true gem install jekyll
----
If you encounter errors like +Failed to build gem native extension+ on Windows
you may need to install http://wiki.github.com/oneclick/rubyinstaller/development-kit[RubyInstaller
DevKit].
==== LaTeX to PNG
Maruku comes with optional support for LaTeX to PNG rendering via blahtex
(Version 0.6) which must be in your $PATH along with @dvips@.
(NOTE: "remi's fork of Maruku":http://github.com/remi/maruku/tree/master does
not assume a fixed location for @dvips@ if you need that fixed)
==== RDiscount
If you prefer to use
http://github.com/rtomayko/rdiscount/tree/master[RDiscount] instead of
http://maruku.rubyforge.org/[Maruku] for markdown, just make sure it's
installed:
----
sudo gem install rdiscount
----
And run Jekyll with the following option:
----
jekyll --rdiscount
----
Or, in your @_config.yml@ file put the following so you don't have to specify the flag:
----
markdown: rdiscount
----
==== Pygments
If you want syntax highlighting via the @{% highlight %}@ tag in your posts,
you'll need to install http://pygments.org/[Pygments].
.On OSX with Homebrew
----
brew install pip && pip install pygments
----
.On OSX with MacPorts
----
sudo port install python25 py25-pygments
----
.Bare OS X Leopard
----
sudo easy_install Pygments
----
.Archlinux
----
sudo pacman -S python-pygments
----
.Archlinux python2 for Pygments
----
$ sudo pacman -S python2-pygments
----
NOTE: python2 pygments version creates a `pygmentize2` executable, while
Jekyll tries to find `pygmentize`. Either create a symlink `# ln -s
/usr/bin/pygmentize2 /usr/bin/pygmentize` or use the python3 version.
.Ubuntu and Debian
----
sudo apt-get install python-pygments
----
.Gentoo
----
$ sudo emerge -av dev-python/pygments
----
=== Creating your First Site
Jekyll comes with a handy generator that will create a barebones skeleton site
to help you get up and running in no time. Simply create an empty directory to
contain your site, navigate to it, and run the generator command:
----
$ mkdir mysite
$ cd mysite
$ jekyll gen
----
Make sure the directory is empty or Jekyll will refuse to run. If everything
was successful, you'll be left with a complete, valid Jekyll site that's ready
to be converted into a static site.
To perform the conversion, make sure you're in the root of your Jekyll site
directory and run:
----
$ jekyll --server
----
If all goes well, you should get a few lines with information about config
file detection, source and destination paths, and a success message.
The `--server` command line option fires up a simple web server that will
serve the static site we just generated so that we can easily preview what it
will look like once we deploy it to a production environment.
Open up your favorite web browser and navigate to:
----
http://localhost:4000
----
Congratulations! You have now successfully created and converted your first
Jekyll site!

== Chapter 2: Directory Layout
If you followed the Quick Start in the last chapter, you have a Jekyll site on
your local machine. Let's take a closer look at it and see what makes it tick.
The file layout should look something like this:
----
.
|-- _config.yml
|-- _layouts
| |-- default.html
| `-- post.html
|-- _posts
| |-- 2007-10-29-why-every-programmer-should-play-nethack.textile
| `-- 2009-04-26-barcamp-boston-4-roundup.textile
|-- _site
|-- images
| `-- logo.png
`-- index.html
----
Notice that some of the files and directories begin with an underscore. These
have special meaning to Jekyll. The underscore ensures that they will not
interfere with the rest of your site's normal content. It also means that if
any of your normal files start with an underscore, they will cause problems,
so try to avoid this.
=== _config.yml
This file stores configuration data. A majority of these options can be
specified from the command line executable but it's easier to throw them in
here so you don't have to type them out every time. Detailed explanations of
configuration directives can be found in Chapter X.
=== _layouts
Files in this directory represent templates that can be used to wrap converted
pages. Layouts are defined on a page-by-page basis in the YAML front matter.
The liquid tag +{{ content }}+ specifies where the content will be placed
during the conversion process.
=== _posts
If you're using Jekyll as a blog engine, this is where you'll place your blog
posts. A post's filename contains several pieces of data, so you must be very
careful about how these files are named. The filename format is:
+YEAR-MONTH-DATE-SLUG.MARKUP+. The YEAR must be four numbers and the MONTH and
DATE must be two numbers each. The SLUG is what will appear in the URL. The
MARKUP tells Jekyll the format of the post. The date and slug will be used
along with any permalink options you specify (See Chapter X) to construct the
final URL of the post.
=== _site
This is where the generated site will be placed (by default) once Jekyll is
done transforming it. If you're using version control, you'll want to add this
directory to the list of files to be ignored.
=== Normal Files with YAML Front Matter
All files outside of the special underscore directories and that do not
themselves begin with an underscore will be scanned by Jekyll and subjected to
conversion if they contain any YAML front matter.
=== Everything Else
Any files and directories that do not fall into one of the above categories
will be copied to the static site as-is without modification. In this example,
+images/logo.png+ will be copied to the same location in the generated site.
h2. Running Jekyll
Usually this is done through the @jekyll@ executable, which is installed with
the gem. In order to get a server up and running with your Jekyll site, run:
@jekyll --server@
and then browse to http://0.0.0.0:4000. There's plenty of [[configuration
options|Configuration]] available to you as well.
On Debian or Ubuntu, you may need to add @/var/lib/gems/1.8/bin/@ to your path.
h2. Deployment
Since Jekyll simply generates a folder filled with HTML files, it can be
served using practically any available web server out there. Please check the
[[Deployment]] page for more information regarding specific scenarios.

title: Assets
permalink: /docs/assets/

Jekyll provides built-in support for Sass and can work with CoffeeScript via
a Ruby gem. In order to use them, you must first create a file with the
proper extension name (one of `.sass`, `.scss`, or `.coffee`) and ***start the
file with two lines of triple dashes***, like this:
```sass
---
---
// start content
.my-definition
font-size: 1.2em
```
Jekyll treats these files the same as a regular page, in that the output file
will be placed in the same directory that it came from. For instance, if you
have a file named `css/styles.scss` in your site's source folder, Jekyll
will process it and put it in your site's destination folder under
`css/styles.css`.
<div class="note info">
<h5>Jekyll processes all Liquid filters and tags in asset files</h5>
<p>If you are using <a href="https://mustache.github.io">Mustache</a>
or another JavaScript templating language that conflicts with
the <a href="/docs/templates/">Liquid template syntax</a>, you
will need to place <code>{&#37; raw &#37;}</code> and
<code>{&#37; endraw &#37;}</code> tags around your code.</p>
</div>
## Sass/SCSS
Jekyll allows you to customize your Sass conversion in certain ways.
Place all your partials in your `sass_dir`, which defaults to
`<source>/_sass`. Place your main SCSS or Sass files in the place you want
them to be in the output file, such as `<source>/css`. For an example, take
a look at [this example site using Sass support in Jekyll][example-sass].
If you are using Sass `@import` statements, you'll need to ensure that your
`sass_dir` is set to the base directory that contains your Sass files. You
can do that thusly:
```yaml
sass:
sass_dir: _sass
```
The Sass converter will default the `sass_dir` configuration option to
`_sass`.
[example-sass]: https://github.com/jekyll/jekyll-sass-converter/tree/master/example
<div class="note info">
<h5>The <code>sass_dir</code> is only used by Sass</h5>
<p>
Note that the <code>sass_dir</code> becomes the load path for Sass imports,
nothing more. This means that Jekyll does not know about these files
directly, so any files here should not contain the YAML Front Matter as
described above nor will they be transformed as described above. This
folder should only contain imports.
</p>
</div>
You may also specify the output style with the `style` option in your
`_config.yml` file:
```yaml
sass:
style: compressed
```
These are passed to Sass, so any output style options Sass supports are valid
here, too.
## Coffeescript
To enable Coffeescript in Jekyll 3.0 and up you must
* Install the `jekyll-coffeescript` gem
* Ensure that your `_config.yml` is up-to-date and includes the following:
```yaml
plugins:
- jekyll-coffeescript
```

title: Collections
permalink: /docs/collections/
---
Not everything is a post or a page. Maybe you want to document the various
methods in your open source project, members of a team, or talks at a
conference. Collections allow you to define a new type of document that behave
like Pages or Posts do normally, but also have their own unique properties and
namespace.
## Using Collections
To start using collections, follow these 3 steps:
* [Step 1: Tell Jekyll to read in your collection](#step1)
* [Step 2: Add your content](#step2)
* [Step 3: Optionally render your collection's documents into independent files](#step3)
### Step 1: Tell Jekyll to read in your collection {#step1}
Add the following to your site's `_config.yml` file, replacing `my_collection`
with the name of your collection:
```yaml
collections:
- my_collection
```
You can optionally specify metadata for your collection in the configuration:
```yaml
collections:
my_collection:
foo: bar
```
Default attributes can also be set for a collection:
```yaml
defaults:
- scope:
path: ""
type: my_collection
values:
layout: page
```
### Step 2: Add your content {#step2}
Create a corresponding folder (e.g. `<source>/_my_collection`) and add
documents. YAML front matter is processed if the front matter exists, and everything
after the front matter is pushed into the document's `content` attribute. If no YAML front
matter is provided, Jekyll will not generate the file in your collection.
<div class="note info">
<h5>Be sure to name your directories correctly</h5>
<p>
The folder must be named identically to the collection you defined in
your <code>_config.yml</code> file, with the addition of the preceding <code>_</code> character.
</p>
</div>
### Step 3: Optionally render your collection's documents into independent files {#step3}
If you'd like Jekyll to create a public-facing, rendered version of each
document in your collection, set the `output` key to `true` in your collection
metadata in your `_config.yml`:
```yaml
collections:
my_collection:
output: true
```
This will produce a file for each document in the collection.
For example, if you have `_my_collection/some_subdir/some_doc.md`,
it will be rendered using Liquid and the Markdown converter of your
choice and written out to `<dest>/my_collection/some_subdir/some_doc.html`.
<div class="note info">
<h5>Don't forget to add YAML for processing</h5>
<p>
Files in collections that do not have front matter are treated as
<a href="/docs/static-files">static files</a> and simply copied to their
output location without processing.
</p>
</div>
## Configuring permalinks for collections {#permalinks}
If you wish to specify a custom pattern for the URLs where your Collection pages
will reside, you may do so with the [`permalink` property](../permalinks/):
```yaml
collections:
my_collection:
output: true
permalink: /:collection/:name
```
### Examples
For a collection with the following source file structure,
```
_my_collection/
└── some_subdir
└── some_doc.md
```
each of the following `permalink` configurations will produce the document structure shown below it.
* **Default**
Same as `permalink: /:collection/:path`.
```
_site/
├── my_collection
│   └── some_subdir
│   └── some_doc.html
...
```
* `permalink: pretty`
Same as `permalink: /:collection/:path/`.
```
_site/
├── my_collection
│   └── some_subdir
│   └── some_doc
│   └── index.html
...
```
* `permalink: /doc/:path`
```
_site/
├── doc
│   └── some_subdir
│   └── some_doc.html
...
```
* `permalink: /doc/:name`
```
_site/
├── doc
│   └── some_doc.html
...
```
* `permalink: /:name`
```
_site/
├── some_doc.html
...
```

<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>:collection</code></p>
</td>
<td>
<p>Label of the containing collection.</p>

</td>
<td>
<p>The document's lowercase title (as defined in its <a href="/docs/frontmatter/">front matter</a>), with every sequence of spaces and non-alphanumeric characters replaced by a hyphen. If the document does not define a title in its <a href="/docs/frontmatter/">front matter</a>, this is equivalent to <code>name</code>.</p>

## Liquid Attributes
### Collections
Each collection is accessible as a field on the `site` variable. For example, if
you want to access the `albums` collection found in `_albums`, you'd use
`site.albums`.
Each collection is itself an array of documents (e.g., `site.albums` is an array of documents, much like `site.pages` and
`site.posts`). See the table below for how to access attributes of those documents.
The collections are also available under `site.collections`, with the metadata
you specified in your `_config.yml` (if present) and the following information:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>label</code></p>
</td>
<td>
<p>
The name of your collection, e.g. <code>my_collection</code>.
</p>
</td>
</tr>
<tr>
<td>
<p><code>docs</code></p>
</td>
<td>
<p>
An array of <a href="#documents">documents</a>.
</p>
</td>
</tr>
<tr>
<td>
<p><code>files</code></p>
</td>
<td>
<p>
An array of static files in the collection.
</p>
</td>
</tr>
<tr>
<td>
<p><code>relative_directory</code></p>
</td>
<td>
<p>
The path to the collection's source directory, relative to the site
source.
</p>
</td>
</tr>
<tr>
<td>
<p><code>directory</code></p>
</td>
<td>
<p>
The full path to the collections's source directory.
</p>
</td>
</tr>
<tr>
<td>
<p><code>output</code></p>
</td>
<td>
<p>
Whether the collection's documents will be output as individual
files.
</p>
</td>
</tr>
</tbody>
</table>
</div>
<div class="note info">
<h5>A Hard-Coded Collection</h5>
<p>In addition to any collections you create yourself, the
<code>posts</code> collection is hard-coded into Jekyll. It exists whether
you have a <code>_posts</code> directory or not. This is something to note
when iterating through <code>site.collections</code> as you may need to
filter it out.</p>
<p>You may wish to use filters to find your collection:
<code>{% raw %}{{ site.collections | where: "label", "myCollection" | first }}{% endraw %}</code></p>
</div>
### Documents
In addition to any YAML Front Matter provided in the document's corresponding
file, each document has the following attributes:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>content</code></p>
</td>
<td>
<p>
The (unrendered) content of the document. If no YAML Front Matter is
provided, Jekyll will not generate the file in your collection. If
YAML Front Matter is used, then this is all the contents of the file
after the terminating
`---` of the front matter.
</p>
</td>
</tr>
<tr>
<td>
<p><code>output</code></p>
</td>
<td>
<p>
The rendered output of the document, based on the
<code>content</code>.
</p>
</td>
</tr>
<tr>
<td>
<p><code>path</code></p>
</td>
<td>
<p>
The full path to the document's source file.
</p>
</td>
</tr>
<tr>
<td>
<p><code>relative_path</code></p>
</td>
<td>
<p>
The path to the document's source file relative to the site source.
</p>
</td>
</tr>
<tr>
<td>
<p><code>url</code></p>
</td>
<td>
<p>
The URL of the rendered collection. The file is only written to the destination when the collection to which it belongs has <code>output: true</code> in the site's configuration.
</p>
</td>
</tr>
<tr>
<td>
<p><code>collection</code></p>
</td>
<td>
<p>
The name of the document's collection.
</p>
</td>
</tr>
<tr>
<td>
<p><code>date</code></p>
</td>
<td>
<p>
The date of the document's collection.
</p>
</td>
</tr>
</tbody>
</table>
</div>
## Accessing Collection Attributes
Attributes from the YAML front matter can be accessed as data anywhere in the
site. Using the above example for configuring a collection as `site.albums`,
you might have front matter in an individual file structured as follows (which
must use a supported markup format, and cannot be saved with a `.yaml`
extension):
```yaml
title: "Josquin: Missa De beata virgine and Missa Ave maris stella"
artist: "The Tallis Scholars"
director: "Peter Phillips"
works:
- title: "Missa De beata virgine"
composer: "Josquin des Prez"
tracks:
- title: "Kyrie"
duration: "4:25"
- title: "Gloria"
duration: "9:53"
- title: "Credo"
duration: "9:09"
- title: "Sanctus & Benedictus"
duration: "7:47"
- title: "Agnus Dei I, II & III"
duration: "6:49"
```
Every album in the collection could be listed on a single page with a template:
```html
{% raw %}
{% for album in site.albums %}
<h2>{{ album.title }}</h2>
<p>Performed by {{ album.artist }}{% if album.director %}, directed by {{ album.director }}{% endif %}</p>
{% for work in album.works %}
<h3>{{ work.title }}</h3>
<p>Composed by {{ work.composer }}</p>
<ul>
{% for track in work.tracks %}
<li>{{ track.title }} ({{ track.duration }})</li>
{% endfor %}
</ul>
{% endfor %}
{% endfor %}
{% endraw %}
```

Jekyll allows you to concoct your sites in any way you can dream up, and its
thanks to the powerful and flexible configuration options that this is possible.
These options can either be specified in a `_config.yml` file placed in your
sites root directory, or can be specified as flags for the `jekyll` executable
in the terminal.
## Configuration Settings
### Global Configuration
The table below lists the available settings for Jekyll, and the various <code

<div class="note warning">
<h5>Do not use tabs in configuration files</h5>
<p>
This will either lead to parsing errors, or Jekyll will revert to the
default settings. Use spaces instead.
</p>
</div>
## Custom WEBrick Headers
You can provide custom headers for your site by adding them to `_config.yml`
```yaml
# File: _config.yml
webrick:
headers:
My-Header: My-Value
My-Other-Header: My-Other-Value
```
### Defaults
We provide by default `Content-Type` and `Cache-Control` response headers: one
dynamic in order to specify the nature of the data being served, the other
static in order to disable caching so that you don't have to fight with Chrome's
aggressive caching when you are in development mode.
## Specifying a Jekyll environment at build time
In the build (or serve) arguments, you can specify a Jekyll environment and value. The build will then apply this value in any conditional statements in your content.
For example, suppose you set this conditional statement in your code:
```liquid
{% raw %}
{% if jekyll.environment == "production" %}
{% include disqus.html %}
{% endif %}
{% endraw %}
```
When you build your Jekyll site, the content inside the `if` statement won't be run unless you also specify a `production` environment in the build command, like this:
```sh
JEKYLL_ENV=production jekyll build
```
Specifying an environment value allows you to make certain content available only within specific environments.
The default value for `JEKYLL_ENV` is `development`. Therefore if you omit `JEKYLL_ENV` from the build arguments, the default value will be `JEKYLL_ENV=development`. Any content inside `{% raw %}{% if jekyll.environment == "development" %}{% endraw %}` tags will automatically appear in the build.
Your environment values can be anything you want (not just `development` or `production`). Some elements you might want to hide in development environments include Disqus comment forms or Google Analytics. Conversely, you might want to expose an "Edit me in GitHub" button in a development environment but not include it in production environments.
By specifying the option in the build command, you avoid having to change values in your configuration files when moving from one environment to another.
## Front Matter defaults
Using [YAML Front Matter](../frontmatter/) is one way that you can specify configuration in the pages and posts for your site. Setting things like a default layout, or customizing the title, or specifying a more precise date/time for the post can all be added to your page or post front matter.
Often times, you will find that you are repeating a lot of configuration options. Setting the same layout in each file, adding the same category - or categories - to a post, etc. You can even add custom variables like author names, which might be the same for the majority of posts on your blog.
Instead of repeating this configuration each time you create a new post or page, Jekyll provides a way to set these defaults in the site configuration. To do this, you can specify site-wide defaults using the `defaults` key in the `_config.yml` file in your project's root directory.
The `defaults` key holds an array of scope/values pairs that define what defaults should be set for a particular file path, and optionally, a file type in that path.
Let's say that you want to add a default layout to all pages and posts in your site. You would add this to your `_config.yml` file:
```yaml
defaults:
-
scope:
path: "" # an empty string here means all files in the project
values:
layout: "default"
```
<div class="note info">
<h5>Please stop and rerun `jekyll serve` command.</h5>
<p>
The <code>_config.yml</code> master configuration file contains global configurations
and variable definitions that are read once at execution time. Changes made to <code>_config.yml</code>
during automatic regeneration are not loaded until the next execution.
</p>
<p>
Note <a href="../datafiles">Data Files</a> are included and reloaded during automatic regeneration.
</p>
</div>
Here, we are scoping the `values` to any file that exists in the path `scope`. Since the path is set as an empty string, it will apply to **all files** in your project. You probably don't want to set a layout on every file in your project - like css files, for example - so you can also specify a `type` value under the `scope` key.
```yaml
defaults:
-
scope:
path: "" # an empty string here means all files in the project
type: "posts" # previously `post` in Jekyll 2.2.
values:
layout: "default"
```
Now, this will only set the layout for files where the type is `posts`.
The different types that are available to you are `pages`, `posts`, `drafts` or any collection in your site. While `type` is optional, you must specify a value for `path` when creating a `scope/values` pair.
As mentioned earlier, you can set multiple scope/values pairs for `defaults`.
```yaml
defaults:
-
scope:
path: ""
type: "posts"
values:
layout: "my-site"
-
scope:
path: "projects"
type: "pages" # previously `page` in Jekyll 2.2.
values:
layout: "project" # overrides previous default layout
author: "Mr. Hyde"
```
With these defaults, all posts would use the `my-site` layout. Any html files that exist in the `projects/` folder will use the `project` layout, if it exists. Those files will also have the `page.author` [liquid variable](../variables/) set to `Mr. Hyde`.
```yaml
collections:
my_collection:
output: true
defaults:
-
scope:
path: ""
type: "my_collection" # a collection in your site, in plural form
values:
layout: "default"
```
In this example, the `layout` is set to `default` inside the
[collection](../collections/) with the name `my_collection`.
### Precedence
Jekyll will apply all of the configuration settings you specify in the `defaults` section of your `_config.yml` file. However, you can choose to override settings from other scope/values pair by specifying a more specific path for the scope.
You can see that in the second to last example above. First, we set the default layout to `my-site`. Then, using a more specific path, we set the default layout for files in the `projects/` path to `project`. This can be done with any value that you would set in the page or post front matter.
Finally, if you set defaults in the site configuration by adding a `defaults` section to your `_config.yml` file, you can override those settings in a post or page file. All you need to do is specify the settings in the post or page front matter. For example:
```yaml
# In _config.yml
...
defaults:
-
scope:
path: "projects"
type: "pages"
values:
layout: "project"
author: "Mr. Hyde"
category: "project"
...
```
```yaml
# In projects/foo_project.md
---
author: "John Smith"
layout: "foobar"
---
The post text goes here...
```
The `projects/foo_project.md` would have the `layout` set to `foobar` instead
of `project` and the `author` set to `John Smith` instead of `Mr. Hyde` when
the site is built.
## Default Configuration
Jekyll runs with the following configuration options by default. Alternative
settings for these options can be explicitly specified in the configuration
file or on the command-line.
<div class="note warning">
<h5>There are two unsupported kramdown options</h5>
<p>

```
## Liquid Options
Liquid's response to errors can be configured by setting `error_mode`. The
options are
- `lax` --- Ignore all errors.
- `warn` --- Output a warning on the console for each error.
- `strict` --- Output an error message and stop the build.
## Markdown Options
The various Markdown renderers supported by Jekyll sometimes have extra options
available.
### Redcarpet
Redcarpet can be configured by providing an `extensions` sub-setting, whose
value should be an array of strings. Each string should be the name of one of
the `Redcarpet::Markdown` class's extensions; if present in the array, it will
set the corresponding extension to `true`.
Jekyll handles two special Redcarpet extensions:
- `no_fenced_code_blocks` --- By default, Jekyll sets the `fenced_code_blocks`
extension (for delimiting code blocks with triple tildes or triple backticks)
to `true`, probably because GitHub's eager adoption of them is starting to make
them inescapable. Redcarpet's normal `fenced_code_blocks` extension is inert
when used with Jekyll; instead, you can use this inverted version of the
extension for disabling fenced code.
Note that you can also specify a language for highlighting after the first
delimiter:
```ruby
# ...ruby code
```
With both fenced code blocks and highlighter enabled, this will statically
highlight the code; without any syntax highlighter, it will add a
`class="LANGUAGE"` attribute to the `<code>` element, which can be used as a
hint by various JavaScript code highlighting libraries.
- `smart` --- This pseudo-extension turns on SmartyPants, which converts
straight quotes to curly quotes and runs of hyphens to em (`---`) and en (`--`) dashes.
All other extensions retain their usual names from Redcarpet, and no renderer
options aside from `smart` can be specified in Jekyll. [A list of available
extensions can be found in the Redcarpet README file.][redcarpet_extensions]
Make sure you're looking at the README for the right version of
Redcarpet: Jekyll currently uses v3.2.x. The most commonly used
extensions are:
- `tables`
- `no_intra_emphasis`
- `autolink`
[redcarpet_extensions]: https://github.com/vmg/redcarpet/blob/v3.2.2/README.markdown#and-its-like-really-simple-to-use
### Custom Markdown Processors
If you're interested in creating a custom markdown processor, you're in luck! Create a new class in the `Jekyll::Converters::Markdown` namespace:
```ruby
class Jekyll::Converters::Markdown::MyCustomProcessor
def initialize(config)
require 'funky_markdown'
@config = config
rescue LoadError
STDERR.puts 'You are missing a library required for Markdown. Please run:'
STDERR.puts ' $ [sudo] gem install funky_markdown'
raise FatalException.new("Missing dependency: funky_markdown")
end
def convert(content)
::FunkyMarkdown.new(content).convert
end
end
```
Once you've created your class and have it properly set up either as a plugin
in the `_plugins` folder or as a gem, specify it in your `_config.yml`:
```yaml
markdown: MyCustomProcessor
```
## Incremental Regeneration
<div class="note warning">
<h5>Incremental regeneration is still an experimental feature</h5>
<p>
While incremental regeneration will work for the most common cases, it will
not work correctly in every scenario. Please be extremely cautious when
using the feature, and report any problems not listed below by
<a href="https://github.com/jekyll/jekyll/issues/new">opening an issue on GitHub</a>.
</p>
</div>
Incremental regeneration helps shorten build times by only generating documents
and pages that were updated since the previous build. It does this by keeping
track of both file modification times and inter-document dependencies in the
`.jekyll-metadata` file.
Under the current implementation, incremental regeneration will only generate a
document or page if either it, or one of its dependencies, is modified. Currently,
the only types of dependencies tracked are includes (using the
{% raw %}`{% include %}`{% endraw %} tag) and layouts. This means that plain
references to other documents (for example, the common case of iterating over
`site.posts` in a post listings page) will not be detected as a dependency.
To remedy some of these shortfalls, putting `regenerate: true` in the front-matter
of a document will force Jekyll to regenerate it regardless of whether it has been
modified. Note that this will generate the specified document only; references
to other documents' contents will not work since they won't be re-rendered.
Incremental regeneration can be enabled via the `--incremental` flag (`-I` for
short) from the command-line or by setting `incremental: true` in your
configuration file.

title: "BuddyWorks"
---
[BuddyWorks][buddyworks-homepage] is a [Docker][docker-homepage]-based CI server that you can set up in 15-20 minutes to build, test, and deploy your Jekyll websites. It supports [GitHub][github-homepage], [Bitbucket][bitbucket-homepage], and [GitLab][gitlab-homepage] repositories, and can be installed on-premises or used in cloud. The following guide will show you how to set up a free environment to build and test your Jekyll project.
[buddyworks-homepage]: https://buddy.works
[docker-homepage]: https://www.docker.com/
[github-homepage]: https://github.com
[bitbucket-homepage]: https://bitbucket.org/
[gitlab-homepage]: https://gitlab.com
## 1. Getting started
1. Log in at [https://buddy.works](https://buddy.works) with your GitHub/Bitbucket account or email
2. Choose your Git provider and select or push your Jekyll Project
3. Create a new pipeline and set the trigger mode to 'On every push'
4. Add and configure the Jekyll action and save the pipeline
## 2. How it works
Whenever you make a push to the selected branch, the Jekyll action runs `jekyll build` in an isolated [Jekyll Docker image][jekyll-docker-image]. The output is generated to the `/filesystem` directory, and can be further deployed to FTP/SFTP and IaaS services. You can add your own commands, install additional packages, attach services, and run Selenium tests, as well as add other actions down the pipeline, eg. a Slack notification or an SSH script that will restart your server.
![Jekyll Build](https://buddy.works/data/blog/_images/buddyworks-jekyll-small.png)
[jekyll-docker-image]: https://hub.docker.com/r/jekyll/jekyll/
## 3. Using YAML for configuration
If you prefer configuration as code over GUI, you can generate a `buddy.yml` that will create a pipeline with the Jekyll action once you push it to the target branch:
```ruby
- pipeline: "Build and Deploy Jekyll site"
trigger_mode: "ON_EVERY_PUSH"
ref_name: "master"
actions:
- action: "Execute: jekyll build"
type: "BUILD"
docker_image_name: "jekyll/jekyll"
docker_image_tag: "latest"
execute_commands:
- "chown jekyll:jekyll $WORKING_DIR"
- "jekyll build"
```
## 4. Setting up on-premises server
The self-hosted version of BuddyWorks can be installed on any type of server supporting Docker, including [Linux][bw-linux], [Mac][bw-mac], [AWS EC2][bw-aws-ec2], [DigitalOcean][bw-digitalocean], and [Microsoft Azure][bw-azure].

title: "CircleCI"
---
Building, testing, and deploying your Jekyll-generated website can quickly be done with [CircleCI][0], a continuous integration & delivery tool. CircleCI supports [GitHub][1] and [Bitbucket][2], and you can get started for free using an open-source or private repository.
[0]: https://circleci.com/
[1]: https://github.com/
[2]: https://bitbucket.org/
## 1. Follow Your Project on CircleCI
To start building your project on CircleCI, all you need to do is 'follow' your project from CircleCI's website:
1. Visit the 'Add Projects' page: <https://circleci.com/add-projects>
1. From the GitHub or Bitbucket tab on the left, choose a user or organization.
1. Find your project in the list and click 'Build project' on the right.
1. The first build will start on its own. You can start telling CircleCI how to build your project by creating a [circle.yml][3] file in the root of your repository.
[3]: https://circleci.com/docs/configuration/
## 2. Dependencies
The easiest way to manage dependencies for a Jekyll project (with or without CircleCI) is via a [Gemfile][4]. You'd want to have Jekyll, any Jekyll plugins, [HTML Proofer](#html-proofer), and any other gems that you are using in the `Gemfile`. Don't forget to version `Gemfile.lock` as well. Here's an example `Gemfile`:
[4]: http://bundler.io/gemfile.html
```yaml
source 'https://rubygems.org'
ruby '2.4.0'
gem 'jekyll'
gem 'html-proofer'
```
CircleCI detects when `Gemfile` is present is will automatically run `bundle install` for you in the `dependencies` phase.
## 3. Testing
The most basic test that can be run is simply seeing if `jekyll build` actually works. This is a blocker, a dependency if you will, for other tests you might run on the generate site. So we'll run Jekyll, via Bundler, in the `dependencies` phase.
```
dependencies:
post:
- bundle exec jekyll build
```
### HTML Proofer
With your site built, it's useful to run tests to check for valid HTML, broken links, etc. There's a few tools out there but [HTML Proofer][5] is popular amongst Jekyll users. We'll run it in the `test` phase with a few preferred flags. Check out the `html-proofer` [README][6] for all available flags, or run `htmlproofer --help` locally.
[5]: https://github.com/gjtorikian/html-proofer
[6]: https://github.com/gjtorikian/html-proofer/blob/master/README.md#configuration
```yaml
test:
post:
- bundle exec htmlproofer ./_site --check-html --disable-external
```
## Complete Example circle.yml File
When you put it all together, here's an example of what that `circle.yml` file could look like:
```
machine:
environment:
NOKOGIRI_USE_SYSTEM_LIBRARIES: true # speeds up installation of html-proofer
dependencies:
post:
- bundle exec jekyll build
test:
post:
- bundle exec htmlproofer ./_site --allow-hash-href --check-favicon --check-html --disable-external
deployment:
prod:
branch: master
commands:
- rsync -va --delete ./_site username@my-website:/var/html
```
## Questions?

title: "Travis CI"
---
You can easily test your website build against one or more versions of Ruby.
The following guide will show you how to set up a free build environment on
[Travis][travis], with [GitHub][github] integration for pull requests.
[travis]: https://travis-ci.org/
[github]: https://github.com/
## 1. Enabling Travis and GitHub
Enabling Travis builds for your GitHub repository is pretty simple:
1. Go to your profile on travis-ci.org: https://travis-ci.org/profile/username
2. Find the repository for which you're interested in enabling builds.
3. Flick the repository switch on so that it turns blue.
4. Optionally configure the build by clicking on the gear icon. Further
configuration happens via your `.travis.yml` file. More details below.
## 2. The Test Script
The simplest test script simply runs `jekyll build` and ensures that Jekyll
doesn't fail to build the site. It doesn't check the resulting site, but it
does ensure things are built properly.
When testing Jekyll output, there is no better tool than [html-proofer][html-proofer].
This tool checks your resulting site to ensure all links and images exist.
Utilize it either with the convenient `htmlproofer` command-line executable,
or write a Ruby script which utilizes the gem.
Save the commands you want to run and succeed in a file: `./script/cibuild`
### The HTML Proofer Executable
```sh
#!/usr/bin/env bash
set -e # halt script on error
bundle exec jekyll build
bundle exec htmlproofer ./_site
```
Some options can be specified via command-line switches. Check out the
`html-proofer` README for more information about these switches, or run
`htmlproofer --help` locally.
For example to avoid testing external sites, use this command:
```sh
$ bundle exec htmlproofer ./_site --disable-external
```
### The HTML Proofer Library
You can also invoke `html-proofer` in Ruby scripts (e.g. in a Rakefile):
```ruby
#!/usr/bin/env ruby
require 'html-proofer'
HTMLProofer.check_directory("./_site").run
```
Options are given as a second argument to `.new`, and are encoded in a
symbol-keyed Ruby Hash. For more information about the configuration options,
check out `html-proofer`'s README file.
[html-proofer]: https://github.com/gjtorikian/html-proofer
## 3. Configuring Your Travis Builds
This file is used to configure your Travis builds. Because Jekyll is built
with Ruby and requires RubyGems to install, we use the Ruby language build
environment. Below is a sample `.travis.yml` file, followed by
an explanation of each line.
**Note:** You will need a Gemfile as well, [Travis will automatically install](https://docs.travis-ci.com/user/languages/ruby/#Dependency-Management) the dependencies based on the referenced gems:
```ruby
source "https://rubygems.org"
gem "jekyll"
gem "html-proofer"
```
Your `.travis.yml` file should look like this:
```yaml
language: ruby
rvm:
- 2.3.3
before_script:
- chmod +x ./script/cibuild # or do this locally and commit
# Assume bundler is being used, therefore
# the `install` step will run `bundle install` by default.
script: ./script/cibuild
# branch whitelist, only for GitHub Pages
branches:
only:
- gh-pages # test the gh-pages branch
- /pages-(.*)/ # test every branch which starts with "pages-"
env:
global:
- NOKOGIRI_USE_SYSTEM_LIBRARIES=true # speeds up installation of html-proofer
sudo: false # route your build to the container-based infrastructure for a faster build
```
Ok, now for an explanation of each line:
```yaml
language: ruby
```
This line tells Travis to use a Ruby build container. It gives your script
access to Bundler, RubyGems, and a Ruby runtime.
```yaml
rvm:
- 2.3.3
```
RVM is a popular Ruby Version Manager (like rbenv, chruby, etc). This
directive tells Travis the Ruby version to use when running your test
script.
```yaml
before_script:
- chmod +x ./script/cibuild
```
The build script file needs to have the *executable* attribute set or
Travis will fail with a permission denied error. You can also run this
locally and commit the permissions directly, thus rendering this step
irrelevant.
```yaml
script: ./script/cibuild
```
Travis allows you to run any arbitrary shell script to test your site. One
convention is to put all scripts for your project in the `script`
directory, and to call your test script `cibuild`. This line is completely
customizable. If your script won't change much, you can write your test
incantation here directly:
```yaml
install: gem install jekyll html-proofer
script: jekyll build && htmlproofer ./_site
```
The `script` directive can be absolutely any valid shell command.
```yaml
# branch whitelist, only for GitHub Pages
branches:
only:
- gh-pages # test the gh-pages branch
- /pages-(.*)/ # test every branch which starts with "pages-"
```
You want to ensure the Travis builds for your site are being run only on
the branch or branches which contain your site. One means of ensuring this
isolation is including a branch whitelist in your Travis configuration
file. By specifying the `gh-pages` branch, you will ensure the associated
test script (discussed above) is only executed on site branches. If you use
a pull request flow for proposing changes, you may wish to enforce a
convention for your builds such that all branches containing edits are
prefixed, exemplified above with the `/pages-(.*)/` regular expression.
The `branches` directive is completely optional. Travis will build from every
push to any branch of your repo if leave it out.
```yaml
env:
global:
- NOKOGIRI_USE_SYSTEM_LIBRARIES=true # speeds up installation of html-proofer
```
Using `html-proofer`? You'll want this environment variable. Nokogiri, used
to parse HTML files in your compiled site, comes bundled with libraries
which it must compile each time it is installed. Luckily, you can
dramatically decrease the install time of Nokogiri by setting the
environment variable `NOKOGIRI_USE_SYSTEM_LIBRARIES` to `true`.
<div class="note warning">
<h5>Be sure to exclude <code>vendor</code> from your
<code>_config.yml</code></h5>
<p>Travis bundles all gems in the <code>vendor</code> directory on its build
servers, which Jekyll will mistakenly read and explode on.</p>
</div>
```yaml
exclude: [vendor]
```
By default you should supply the `sudo: false` command to Travis. This command
explicitly tells Travis to run your build on Travis's [container-based
infrastructure](https://docs.travis-ci.com/user/workers/container-based-infrastructure/#Routing-your-build-to-container-based-infrastructure). Running on the container-based infrastructure can often times
speed up your build. If you have any trouble with your build, or if your build
does need `sudo` access, modify the line to `sudo: required`.
```yaml
sudo: false
```
### Troubleshooting
**Travis error:** *"You are trying to install in deployment mode after changing
your Gemfile. Run bundle install elsewhere and add the updated Gemfile.lock
to version control."*
**Workaround:** Either run `bundle install` locally and commit your changes to
`Gemfile.lock`, or remove the `Gemfile.lock` file from your repository and add
an entry in the `.gitignore` file to avoid it from being checked in again.

Hi there! Interested in contributing to Jekyll? We'd love your help. Jekyll is an open source project, built one contribution at a time by users like you.
## Where to get help or report a problem
* If you have a question about using Jekyll, start a discussion on [Jekyll Talk](https://talk.jekyllrb.com).
* If you think you've found a bug within a Jekyll plugin, open an issue in that plugin's repository.
* If you think you've found a bug within Jekyll itself, [open an issue](https://github.com/jekyll/jekyll/issues/new).
* More resources are listed on our [Help page](https://jekyllrb.com/help/).
## Ways to contribute
Whether you're a developer, a designer, or just a Jekyll devotee, there are lots of ways to contribute. Here's a few ideas:
* [Install Jekyll on your computer](https://jekyllrb.com/docs/installation/) and kick the tires. Does it work? Does it do what you'd expect? If not, [open an issue](https://github.com/jekyll/jekyll/issues/new) and let us know.
* Comment on some of the project's [open issues](https://github.com/jekyll/jekyll/issues). Have you experienced the same problem? Know a work around? Do you have a suggestion for how the feature could be better?
* Read through [the documentation](https://jekyllrb.com/docs/home/), and click the "improve this page" button, any time you see something confusing, or have a suggestion for something that could be improved.
* Browse through [the Jekyll discussion forum](https://talk.jekyllrb.com/), and lend a hand answering questions. There's a good chance you've already experienced what another user is experiencing.
* Find [an open issue](https://github.com/jekyll/jekyll/issues) (especially [those labeled `help-wanted`](https://github.com/jekyll/jekyll/issues?q=is%3Aopen+is%3Aissue+label%3Ahelp-wanted)), and submit a proposed fix. If it's your first pull request, we promise we won't bite, and are glad to answer any questions.
* Help evaluate [open pull requests](https://github.com/jekyll/jekyll/pulls), by testing the changes locally and reviewing what's proposed.
## Submitting a pull request
### Pull requests generally
* The smaller the proposed change, the better. If you'd like to propose two unrelated changes, submit two pull requests.
* The more information, the better. Make judicious use of the pull request body. Describe what changes were made, why you made them, and what impact they will have for users.
* Pull requests are easy and fun. If this is your first pull request, it may help to [understand GitHub Flow](https://guides.github.com/introduction/flow/).
* If you're submitting a code contribution, be sure to read the [code contributions](#code-contributions) section below.
### Submitting a pull request via github.com
Many small changes can be made entirely through the github.com web interface.
1. Navigate to the file within [`jekyll/jekyll`](https://github.com/jekyll/jekyll) that you'd like to edit.
2. Click the pencil icon in the top right corner to edit the file
3. Make your proposed changes
4. Click "Propose file change"
5. Click "Create pull request"
6. Add a descriptive title and detailed description for your proposed change. The more information the better.
7. Click "Create pull request"
That's it! You'll be automatically subscribed to receive updates as others review your proposed change and provide feedback.
### Submitting a pull request via Git command line
1. Fork the project by clicking "Fork" in the top right corner of [`jekyll/jekyll`](https://github.com/jekyll/jekyll).
2. Clone the repository locally `git clone https://github.com/<you-username>/jekyll`.
3. Create a new, descriptively named branch to contain your change ( `git checkout -b my-awesome-feature` ).
4. Hack away, add tests. Not necessarily in that order.
5. Make sure everything still passes by running `script/cibuild` (see [the tests section](#running-tests-locally) below)
6. Push the branch up ( `git push origin my-awesome-feature` ).
7. Create a pull request by visiting `https://github.com/<your-username>/jekyll` and following the instructions at the top of the screen.
## Proposing updates to the documentation
We want the Jekyll documentation to be the best it can be. We've open-sourced our docs and we welcome any pull requests if you find it lacking.
### How to submit changes
You can find the documentation for jekyllrb.com in the [docs](https://github.com/jekyll/jekyll/tree/master/docs) directory. See the section above, [submitting a pull request](#submitting-a-pull-request) for information on how to propose a change.
One gotcha, all pull requests should be directed at the `master` branch (the default branch).
### Updating FontAwesome iconset for jekyllrb.com
We use a custom version of FontAwesome which contains just the icons we use.
If you ever need to update our documentation with an icon that is not already available in our custom iconset, you'll have to regenerate the iconset using Icomoon's Generator:
1. Go to <https://icomoon.io/app/>.
2. Click `Import Icons` on the top-horizontal-bar and upload the existing `<jekyll>/docs/icomoon-selection.json`.
3. Click `Add Icons from Library..` further down on the page, and add 'Font Awesome'.
4. Select the required icon(s) from the Library (make sure its the 'FontAwesome' library instead of 'IcoMoon-Free' library).
5. Click `Generate Font` on the bottom-horizontal-bar.
6. Inspect the included icons and proceed by clicking `Download`.
7. Extract the font files and adapt the CSS to the paths we use in Jekyll:
- Copy the entire `fonts` directory over and overwrite existing ones at `<jekyll>/docs/`.
- Copy the contents of `selection.json` and overwrite existing content inside `<jekyll>/docs/icomoon-selection.json`.
- Copy the entire `@font-face {}` declaration and only the **new-icon(s)' css declarations** further below, to update the
`<jekyll>/docs/_sass/_font-awesome.scss` sass partial.
- Fix paths in the `@font-face {}` declaration by adding `../` before `fonts/FontAwesome.*` like so:
`('../fonts/Fontawesome.woff?9h6hxj')`.
### Adding plugins
If you want to add your plugin to the [list of plugins](https://jekyllrb.com/docs/plugins/#available-plugins), please submit a pull request modifying the [plugins page source file](https://github.com/jekyll/jekyll/blob/master/docs/_docs/plugins.md) by adding a link to your plugin under the proper subheading depending upon its type.
## Code Contributions
Interesting in submitting a pull request? Awesome. Read on. There's a few common gotchas that we'd love to help you avoid.
### Tests and documentation
Any time you propose a code change, you should also include updates to the documentation and tests within the same pull request.
#### Documentation
If your contribution changes any Jekyll behavior, make sure to update the documentation. Documentation lives in the `docs/_docs` folder (spoiler alert: it's a Jekyll site!). If the docs are missing information, please feel free to add it in. Great docs make a great project. Include changes to the documentation within your pull request, and once merged, `jekyllrb.com` will be updated.
#### Tests
* If you're creating a small fix or patch to an existing feature, a simple test is more than enough. You can usually copy/paste from an existing example in the `tests` folder, but if you need you can find out about our tests suites [Shoulda](https://github.com/thoughtbot/shoulda/tree/master) and [RSpec-Mocks](https://github.com/rspec/rspec-mocks).
* If it's a brand new feature, create a new [Cucumber](https://github.com/cucumber/cucumber/) feature, reusing existing steps where appropriate.
### Code contributions generally
* Jekyll uses the [Rubocop](https://github.com/bbatsov/rubocop) static analyzer to ensure that contributions follow the [GitHub Ruby Styleguide](https://github.com/styleguide/ruby). Please check your code using `script/fmt` and resolve any errors before pushing your branch.
* Don't bump the Gem version in your pull request (if you don't know what that means, you probably didn't).
## Running tests locally
### Test Dependencies
To run the test suite and build the gem you'll need to install Jekyll's dependencies by running the following command:
<pre class="highlight"><code>$ script/bootstrap</code></pre>
Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
<pre class="highlight"><code>$ script/cibuild</code></pre>
If you are only updating a file in `test/`, you can use the command:
<pre class="highlight"><code>$ script/test test/blah_test.rb</code></pre>
If you are only updating a `.feature` file, you can use the command:
<pre class="highlight"><code>$ script/cucumber features/blah.feature</code></pre>
Both `script/test` and `script/cucumber` can be run without arguments to
run its entire respective suite.
## A thank you
Thanks! Hacking on Jekyll should be fun. If you find any of this hard to figure out, let us know so we can improve our process or documentation!

title: Data Files
permalink: /docs/datafiles/
---
In addition to the [built-in variables](../variables/) available from Jekyll,
you can specify your own custom data that can be accessed via the [Liquid
templating system](https://wiki.github.com/shopify/liquid/liquid-for-designers).
Jekyll supports loading data from [YAML](http://yaml.org/), [JSON](http://www.json.org/),
and [CSV](https://en.wikipedia.org/wiki/Comma-separated_values) files located in the `_data` directory.
Note that CSV files *must* contain a header row.
This powerful feature allows you to avoid repetition in your templates and to
set site specific options without changing `_config.yml`.
Plugins/themes can also leverage Data Files to set configuration variables.
## The Data Folder
As explained on the [directory structure](../structure/) page, the `_data`
folder is where you can store additional data for Jekyll to use when generating
your site. These files must be YAML, JSON, or CSV files (using either
the `.yml`, `.yaml`, `.json` or `.csv` extension), and they will be
accessible via `site.data`.
## Example: List of members
Here is a basic example of using Data Files to avoid copy-pasting large chunks
of code in your Jekyll templates:
In `_data/members.yml`:
```yaml
- name: Eric Mill
github: konklone
- name: Parker Moore
github: parkr
- name: Liu Fengyun
github: liufengyun
```
Or `_data/members.csv`:
```text
name,github
Eric Mill,konklone
Parker Moore,parkr
Liu Fengyun,liufengyun
```
This data can be accessed via `site.data.members` (notice that the filename
determines the variable name).
You can now render the list of members in a template:
```html
{% raw %}
<ul>
{% for member in site.data.members %}
<li>
<a href="https://github.com/{{ member.github }}">
{{ member.name }}
</a>
</li>
{% endfor %}
</ul>
{% endraw %}
```
{: .note .info }
If your Jekyll site has a lot of pages, such as with documentation websites, see the detailed examples in [how to build robust navigation for your site]({% link _tutorials/navigation.md %}).
## Example: Organizations
Data files can also be placed in sub-folders of the `_data` folder. Each folder
level will be added to a variable's namespace. The example below shows how
GitHub organizations could be defined separately in a file under the `orgs`
folder:
In `_data/orgs/jekyll.yml`:
```yaml
username: jekyll
name: Jekyll
members:
- name: Tom Preston-Werner
github: mojombo
- name: Parker Moore
github: parkr
```
In `_data/orgs/doeorg.yml`:
```yaml
username: doeorg
name: Doe Org
members:
- name: John Doe
github: jdoe
```
The organizations can then be accessed via `site.data.orgs`, followed by the
file name:
```html
{% raw %}
<ul>
{% for org_hash in site.data.orgs %}
{% assign org = org_hash[1] %}
<li>
<a href="https://github.com/{{ org.username }}">
{{ org.name }}
</a>
({{ org.members | size }} members)
</li>
{% endfor %}
</ul>
{% endraw %}
```
## Example: Accessing a specific author
Pages and posts can also access a specific data item. The example below shows how to access a specific item:
`_data/people.yml`:
```yaml
dave:
name: David Smith
twitter: DavidSilvaSmith
```
The author can then be specified as a page variable in a post's frontmatter:
```html
{% raw %}
---
title: sample post
author: dave
---
{% assign author = site.data.people[page.author] %}
<a rel="author"
href="https://twitter.com/{{ author.twitter }}"
title="{{ author.name }}">
{{ author.name }}
</a>
{% endraw %}
```

title: Deployment methods
permalink: /docs/deployment-methods/
---
Sites built using Jekyll can be deployed in a large number of ways due to the static nature of the generated output. A few of the most common deployment techniques are described below.
## Web hosting providers (FTP)
Just about any traditional web hosting provider will let you upload files to their servers over FTP. To upload a Jekyll site to a web host using FTP, simply run the `jekyll build` command and copy the contents of the generated `_site` folder to the root folder of your hosting account. This is most likely to be the `httpdocs` or `public_html` folder on most hosting providers.
## Self-managed web server
If you have direct access to the deployment web server, the process is essentially the same, except you might have other methods available to you (such as `scp`, or even direct filesystem access) for transferring the files. Just remember to make sure the contents of the generated `_site` folder get placed in the appropriate web root directory for your web server.
## Automated methods
There are also a number of ways to easily automate the deployment of a Jekyll site. If youve got another method that isnt listed below, wed love it if you [contributed](../contributing/) so that everyone else can benefit too.
### Git post-update hook
If you store your Jekyll site in [Git](https://git-scm.com/) (you are using
version control, right?), its pretty easy to automate the
deployment process by setting up a post-update hook in your Git
repository, [like
this](http://web.archive.org/web/20091223025644/http://www.taknado.com/en/2009/03/26/deploying-a-jekyll-generated-site/).
### Git post-receive hook
To have a remote server handle the deploy for you every time you push changes using Git, you can create a user account which has all the public keys that are authorized to deploy in its `authorized_keys` file. With that in place, setting up the post-receive hook is done as follows:
```sh
laptop$ ssh deployer@example.com
server$ mkdir myrepo.git
server$ cd myrepo.git
server$ git --bare init
server$ cp hooks/post-receive.sample hooks/post-receive
server$ mkdir /var/www/myrepo
```
Next, add the following lines to hooks/post-receive and be sure Jekyll is
installed on the server:
```sh
GIT_REPO=$HOME/myrepo.git
TMP_GIT_CLONE=$HOME/tmp/myrepo
PUBLIC_WWW=/var/www/myrepo
git clone $GIT_REPO $TMP_GIT_CLONE
jekyll build -s $TMP_GIT_CLONE -d $PUBLIC_WWW
rm -Rf $TMP_GIT_CLONE
exit
```
Finally, run the following command on any users laptop that needs to be able to
deploy using this hook:
```sh
laptops$ git remote add deploy deployer@example.com:~/myrepo.git
```
Deploying is now as easy as telling nginx or Apache to look at
`/var/www/myrepo` and running the following:
```sh
laptops$ git push deploy master
```
### Static Publisher
[Static Publisher](https://github.com/static-publisher/static-publisher) is another automated deployment option with a server listening for webhook posts, though it's not tied to GitHub specifically. It has a one-click deploy to Heroku, it can watch multiple projects from one server, it has an easy to user admin interface and can publish to either S3 or to a git repository (e.g. gh-pages).
### Rake
Another way to deploy your Jekyll site is to use [Rake](https://github.com/ruby/rake), [HighLine](https://github.com/JEG2/highline), and
[Net::SSH](https://github.com/net-ssh/net-ssh). A more complex example of deploying Jekyll with Rake that deals with multiple branches can be found in [Git Ready](https://github.com/gitready/gitready/blob/cdfbc4ec5321ff8d18c3ce936e9c749dbbc4f190/Rakefile).
### scp
Once youve generated the `_site` directory, you can easily scp its content using a
`tasks/deploy` shell script similar to [this deploy script][]. Youd obviously
need to change the values to reflect your sites details. There is even [a
matching TextMate command][] that will help you run this script.
[this deploy script]: https://github.com/henrik/henrik.nyh.se/blob/master/script/deploy
[a matching TextMate command]: https://gist.github.com/henrik/214959
### rsync
Once youve generated the `_site` directory, you can easily rsync its content using a `tasks/deploy` shell script similar to [this deploy script here](https://github.com/vitalyrepin/vrepinblog/blob/master/transfer.sh). Youd obviously need to change the values to reflect your sites details.
Certificate-based authorization is another way to simplify the publishing
process. It makes sense to restrict rsync access only to the directory which it is supposed to sync. This can be done using rrsync.
#### Step 1: Install rrsync to your home folder (server-side)
If it is not already installed by your host, you can do it yourself:
- [Download rrsync](https://ftp.samba.org/pub/unpacked/rsync/support/rrsync)
- Place it in the `bin` subdirectory of your home folder (`~/bin`)
- Make it executable (`chmod +x`)
#### Step 2: Set up certificate-based SSH access (server side)
This [process](https://wiki.gentoo.org/wiki/SSH#Passwordless_Authentication) is
described in several places online. What is different from the typical approach
is to put the restriction to certificate-based authorization in
`~/.ssh/authorized_keys`. Then, launch `rrsync` and supply
it with the folder it shall have read-write access to:
```sh
command="$HOME/bin/rrsync <folder>",no-agent-forwarding,no-port-forwarding,no-pty,no-user-rc,no-X11-forwarding ssh-rsa <cert>
```
`<folder>` is the path to your site. E.g., `~/public_html/you.org/blog-html/`.
#### Step 3: Rsync (client-side)
Add the `deploy` script to the site source folder:
```sh
#!/bin/sh
rsync -crvz --rsh='ssh -p2222' --delete-after --delete-excluded <folder> <user>@<site>:
```
Command line parameters are:
- `--rsh=ssh -p2222` &mdash; The port for SSH access. It is required if
your host uses a different port than the default (e.g, HostGator)
- `<folder>` &mdash; The name of the local output folder (defaults to `_site`)
- `<user>` &mdash; The username for your hosting account
- `<site>` &mdash; Your hosting server
Using this setup, you might run the following command:
```sh
rsync -crvz --rsh='ssh -p2222' --delete-after --delete-excluded _site/ hostuser@example.org:
```
Don't forget the column `:` after server name!
#### Step 4 (Optional): Exclude the transfer script from being copied to the output folder.
This step is recommended if you use these instructions to deploy your site. If
you put the `deploy` script in the root folder of your project, Jekyll will
copy it to the output folder. This behavior can be changed in `_config.yml`.
Just add the following line:
```yaml
# Do not copy these files to the output directory
exclude: ["deploy"]
```
Alternatively, you can use an `rsync-exclude.txt` file to control which files will be transferred to your server.
#### Done!
Now it's possible to publish your website simply by running the `deploy`
script. If your SSH certificate is [passphrase-protected](https://martin.kleppmann.com/2013/05/24/improving-security-of-ssh-private-keys.html), you will be asked to enter it when the
script executes.
## Rack-Jekyll
[Rack-Jekyll](https://github.com/adaoraul/rack-jekyll/) is an easy way to deploy your site on any Rack server such as Amazon EC2, Slicehost, Heroku, and so forth. It also can run with [shotgun](https://github.com/rtomayko/shotgun/), [rackup](https://github.com/rack/rack), [mongrel](https://github.com/mongrel/mongrel), [unicorn](https://github.com/defunkt/unicorn/), and [others](https://github.com/adaoraul/rack-jekyll#readme).
Read [this post](http://andycroll.com/ruby/serving-a-jekyll-blog-using-heroku/) on how to deploy to Heroku using Rack-Jekyll.
## Jekyll-Admin for Rails
If you want to maintain Jekyll inside your existing Rails app, [Jekyll-Admin](https://github.com/zkarpinski/Jekyll-Admin) contains drop in code to make this possible. See Jekyll-Admins [README](https://github.com/zkarpinski/Jekyll-Admin/blob/master/README) for more details.
## Amazon S3
If you want to host your site in Amazon S3, you can do so by
using the [s3_website](https://github.com/laurilehmijoki/s3_website)
application. It will push your site to Amazon S3 where it can be served like
any web server,
dynamically scaling to almost unlimited traffic. This approach has the
benefit of being about the cheapest hosting option available for
low-volume blogs as you only pay for what you use.
## OpenShift
If you'd like to deploy your site to an OpenShift gear, there's [a cartridge
for that](https://github.com/openshift-quickstart/jekyll-openshift).

Drafts are posts without a date. They're posts you're still working on and
don't want to publish yet. To get up and running with drafts, create a
`_drafts` folder in your site's root (as described in the [site structure](/docs/structure/) section) and create your
first draft:
```text
|-- _drafts/
| |-- a-draft-post.md
```
To preview your site with drafts, simply run `jekyll serve` or `jekyll build`
with the `--drafts` switch. Each will be assigned the value modification time
of the draft file for its date, and thus you will see currently edited drafts
as the latest posts.

There are a number of (optional) extra features that Jekyll supports that you
may want to install, depending on how you plan to use Jekyll.
## Web Highlights and Commenting
Register your site with [txtpen](https://txtpen.com). Then append
```html
<script src="https://txtpen.com/embed.js?site=<your site name>"></script>
```
to your template files in `/_layout` folder.
## Math Support
Kramdown comes with optional support for LaTeX to PNG rendering via [MathJax](https://www.mathjax.org) within math blocks. See the Kramdown documentation on [math blocks](http://kramdown.gettalong.org/syntax.html#math-blocks) and [math support](http://kramdown.gettalong.org/converter/html.html#math-support) for more details. MathJax requires you to include JavaScript or CSS to render the LaTeX, e.g.
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS-MML_HTMLorMML" type="text/javascript"></script>
```
For more information about getting started, check out [this excellent blog post](http://gastonsanchez.com/visually-enforced/opinion/2014/02/16/Mathjax-with-jekyll/).

title: Front Matter
permalink: /docs/frontmatter/
---
The front matter is where Jekyll starts to get really cool. Any file that
contains a [YAML](http://yaml.org/) front matter block will be processed by
Jekyll as a special file. The front matter must be the first thing in the file
and must take the form of valid YAML set between triple-dashed lines. Here is a
basic example:
```yaml
---
layout: post
title: Blogging Like a Hacker
---
```
Between these triple-dashed lines, you can set predefined variables (see below
for a reference) or even create custom ones of your own. These variables will
then be available to you to access using Liquid tags both further down in the
file and also in any layouts or includes that the page or post in question
relies on.
<div class="note warning">
<h5>UTF-8 Character Encoding Warning</h5>
<p>
If you use UTF-8 encoding, make sure that no <code>BOM</code> header
characters exist in your files or very, very bad things will happen to
Jekyll. This is especially relevant if youre running
<a href="../windows/">Jekyll on Windows</a>.
</p>
</div>
<div class="note">
<h5>ProTip™: Front Matter Variables Are Optional</h5>
<p>
If you want to use <a href="../variables/">Liquid tags and variables</a>
but dont need anything in your front matter, just leave it empty! The set
of triple-dashed lines with nothing in between will still get Jekyll to
process your file. (This is useful for things like CSS and RSS feeds!)
</p>
</div>
## Predefined Global Variables
There are a number of predefined global variables that you can set in the
front matter of a page or post.
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>layout</code></p>
</td>
<td>
<p>
If set, this specifies the layout file to use. Use the layout file
name without the file extension. Layout files must be placed in the
<code>_layouts</code> directory.
</p>
</td>
</tr>
<tr>
<td>
<p><code>permalink</code></p>
</td>
<td>
<p>
If you need your processed blog post URLs to be something other than
the site-wide style (default <code>/year/month/day/title.html</code>), then you can set
this variable and it will be used as the final URL.
</p>
</td>
</tr>
<tr>
<td>
<p><code>published</code></p>

<td>
<p>
Set to false if you dont want a specific post to show up when the
site is generated.

</td>
</tr>
</tbody>
</table>
</div>

<h5>ProTip™: Render Posts Marked As Unpublished</h5>
<p>
To preview unpublished pages, simply run `jekyll serve` or `jekyll build`
with the `--unpublished` switch. Jekyll also has a handy <a href="../drafts/">drafts</a>
feature tailored specifically for blog posts.
</p>
</div>
## Custom Variables
Any variables in the front matter that are not predefined are mixed into the
data that is sent to the Liquid templating engine during the conversion. For
instance, if you set a title, you can use that in your layout to set the page
title:
```html
<!DOCTYPE HTML>
<html>
<head>
<title>{% raw %}{{ page.title }}{% endraw %}</title>
</head>
<body>
...
```
## Predefined Variables for Posts
These are available out-of-the-box to be used in the front matter for a post.
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>date</code></p>
</td>
<td>
<p>
A date here overrides the date from the name of the post. This can be
used to ensure correct sorting of posts. A date is specified in the
format <code>YYYY-MM-DD HH:MM:SS +/-TTTT</code>; hours, minutes, seconds, and timezone offset
are optional.
</p>
</td>
</tr>
<tr>
<td>
<p style="margin-bottom: 5px;"><code>category</code></p>
<p><code>categories</code></p>
</td>
<td>
<p>
Instead of placing posts inside of folders, you can specify one or
more categories that the post belongs to. When the site is generated
the post will act as though it had been set with these categories
normally. Categories (plural key) can be specified as a <a
href="https://en.wikipedia.org/wiki/YAML#Basic_components">YAML list</a> or a
space-separated string.
</p>
</td>
</tr>
<tr>
<td>
<p><code>tags</code></p>
</td>
<td>
<p>
Similar to categories, one or multiple tags can be added to a post.
Also like categories, tags can be specified as a <a

title: GitHub Pages
permalink: /docs/github-pages/
---
[GitHub Pages](https://pages.github.com) are public web pages for users,
organizations, and repositories, that are freely hosted on GitHub's
`github.io` domain or on a custom domain name of your choice. GitHub Pages are
powered by Jekyll behind the scenes, so in addition to supporting regular HTML
content, theyre also a great way to host your Jekyll-powered website for free.
Never built a website with GitHub Pages before? [See this marvelous guide by
Jonathan McGlone to get you up and running](http://jmcglone.com/guides/github-pages/).
This guide will teach you what you need to know about Git, GitHub, and Jekyll to create your very own website on GitHub Pages.
### Project Page URL Structure
Sometimes it's nice to preview your Jekyll site before you push your `gh-pages`
branch to GitHub. However, the subdirectory-like URL structure GitHub uses for
Project Pages complicates the proper resolution of URLs. In order to assure your site builds properly, use `site.github.url` in your URLs.
```html
{% raw %}
<!-- Useful for styles with static names... -->
<link href="{{ site.github.url }}/path/to/css.css" rel="stylesheet">
<!-- and for documents/pages whose URLs can change... -->
[{{ page.title }}]("{{ page.url | prepend: site.github.url }}")
{% endraw %}
```
This way you can preview your site locally from the site root on localhost,
but when GitHub generates your pages from the gh-pages branch all the URLs
will resolve properly.
## Deploying Jekyll to GitHub Pages
GitHub Pages work by looking at certain branches of repositories on GitHub.
There are two basic types available: user/organization pages and project pages.
The way to deploy these two types of sites are nearly identical, except for a
few minor details.
<div class="note protip" markdown="1">
<div markdown="1">
</div>
##### Use the `github-pages` gem
Our friends at GitHub have provided the
[github-pages](https://github.com/github/pages-gem)
gem which is used to manage Jekyll and its dependencies on
GitHub Pages. Using it in your projects means that when you deploy
your site to GitHub Pages, you will not be caught by unexpected
differences between various versions of the gems. To use the
currently-deployed version of the gem in your project, add the
following to your `Gemfile`:
<div class="code-block" markdown="1">
<div markdown="1">
</div>
```ruby
source 'https://rubygems.org'
require 'json'
require 'open-uri'
versions = JSON.parse(open('https://pages.github.com/versions.json').read)
gem 'github-pages', versions['github-pages']
```
</div>
This will ensure that when you run `bundle install`, you
have the correct version of the `github-pages` gem.
If that fails, simplify it:
<div class="code-block" markdown="1">
<div markdown="1">
</div>
```ruby
source 'https://rubygems.org'
gem 'github-pages'
```
</div>
And be sure to run `bundle update` often.
If you like to install `pages-gem` on Windows you can find instructions by Jens Willmer on
[how to install github-pages gem on Windows (x64)](https://jwillmer.de/blog/tutorial/how-to-install-jekyll-and-pages-gem-on-windows-10-x46#github-pages-and-plugins).
</div>
<div class="note info">
<h5>Installing <code>github-pages</code> gem on Windows</h5>
<p>
While Windows is not officially supported, it is possible
to install <code>github-pages</code> gem on Windows.
Special instructions can be found on our
<a href="../windows/#installation">Windows-specific docs page</a>.
</p>
</div>
### User and Organization Pages
User and organization pages live in a special GitHub repository dedicated to
only the GitHub Pages files. This repository must be named after the account
name. For example, [@mojombos user page repository](https://github.com/mojombo/mojombo.github.io) has the name
`mojombo.github.io`.
Content from the `master` branch of your repository will be used to build and
publish the GitHub Pages site, so make sure your Jekyll site is stored there.
<div class="note info">
<h5>Custom domains do not affect repository names</h5>
<p>
GitHub Pages are initially configured to live under the
<code>username.github.io</code> subdomain, which is why repositories must
be named this way <strong>even if a custom domain is being used</strong>.
</p>
</div>
### Project Pages
Unlike user and organization Pages, Project Pages are kept in the same
repository as the project they are for, except that the website content is
stored in a specially named `gh-pages` branch or in a `docs` folder on the
`master` branch. The content will be rendered using Jekyll, and the output
will become available under a subpath of your user pages subdomain, such as
`username.github.io/project` (unless a custom domain is specified).
The Jekyll project repository itself is a perfect example of this branch
structure—the [master branch]({{ site.repository }}) contains the
actual software project for Jekyll, and the Jekyll website that youre
looking at right now is contained in the [docs
folder]({{ site.repository }}/tree/master/docs) of the same repository.
Please refer to GitHub official documentation on
[user, organization and project pages](https://help.github.com/articles/user-organization-and-project-pages/)
to see more detailed examples.
<div class="note warning">
<h5>Source Files Must be in the Root Directory</h5>
<p>
GitHub Pages <a href="https://help.github.com/articles/troubleshooting-github-pages-build-failures#source-setting">overrides</a>
the <a href="/docs/configuration/#global-configuration">“Site Source”</a>
configuration value, so if you locate your files anywhere other than the
root directory, your site may not build correctly.

</div>
<div class="note">

title: Includes
permalink: /docs/includes/
---
The `include` tag allows you to include the content from another file stored in the `_includes` folder:
```liquid
{% raw %}{% include footer.html %}{% endraw %}
```
Jekyll will look for the referenced file (in this case, `footer.html`) in the `_includes` directory at the root of your source directory and insert its contents.
### Including files relative to another file
You can choose to include file fragments relative to the current file by using the `include_relative` tag:
```liquid
{% raw %}{% include_relative somedir/footer.html %}{% endraw %}
```
You won't need to place your included content within the `_includes` directory. Instead,
the inclusion is specifically relative to the file where the tag is being used. For example,
if `_posts/2014-09-03-my-file.markdown` uses the `include_relative` tag, the included file
must be within the `_posts` directory or one of its subdirectories.
Note that you cannot use the `../` syntax to specify an include location that refers to a higher-level directory.
All the other capabilities of the `include` tag are available to the `include_relative` tag,
such as variables.
### Using variables names for the include file
The name of the file you want to embed can be specified as a variable instead of an actual file name. For example, suppose you defined a variable in your page's front matter like this:
```yaml
---
title: My page
my_variable: footer_company_a.html
---
```
You could then reference that variable in your include:
```liquid
{% raw %}{% include {{ page.my_variable }} %}{% endraw %}
```
In this example, the include would insert the file `footer_company_a.html` from the `_includes/footer_company_a.html` directory.
### Passing parameters to includes
You can also pass parameters to an include. For example, suppose you have a file called `note.html` in your `_includes` folder that contains this formatting:
```liquid
{% raw %}<div markdown="span" class="alert alert-info" role="alert">
<i class="fa fa-info-circle"></i> <b>Note:</b>
{{ include.content }}
</div>{% endraw %}
```
The `{% raw %}{{ include.content }}{% endraw %}` is a parameter that gets populated when you call the include and specify a value for that parameter, like this:
```liquid
{% raw %}{% include note.html content="This is my sample note." %} {% endraw %}
```
The value of `content` (which is `This is my sample note`) will be inserted into the {% raw %}`{{ include.content }}`{% endraw %} parameter.
Passing parameters to includes is especially helpful when you want to hide away complex formatting from your Markdown content.
For example, suppose you have a special image syntax with complex formatting, and you don't want your authors to remember the complex formatting. As a result, you decide to simplify the formatting by using an include with parameters. Here's an example of the special image syntax you might want to populate with an include:
```html
<figure>
<a href="http://jekyllrb.com">
<img src="logo.png" style="max-width: 200px;"
alt="Jekyll logo" />
<figcaption>This is the Jekyll logo</figcaption>
</figure>
```
You could templatize this content in your include and make each value available as a parameter, like this:
```liquid
{% raw %}<figure>
<a href="{{ include.url }}">
<img src="{{ include.file }}" style="max-width: {{ include.max-width }};"
alt="{{ include.alt }}"/>
<figcaption>{{ include.caption }}</figcaption>
</figure>{% endraw %}
```
This include contains 5 parameters:
* `url`
* `max-width`
* `file`
* `alt`
* `caption`
Here's an example that passes all the parameters to this include (the include file is named `image.html`):
```liquid
{% raw %}{% include image.html url="http://jekyllrb.com"
max-width="200px" file="logo.png" alt="Jekyll logo"
caption="This is the Jekyll logo." %} {% endraw %}
```
The result is the original HTML code shown earlier.
To safeguard situations where users don't supply a value for the parameter, you can use [Liquid's default filter](https://help.shopify.com/themes/liquid/filters/additional-filters#default).
Overall, you can create includes that act as templates for a variety of uses &mdash; inserting audio or video clips, alerts, special formatting, and more. However, note that you should avoid using too many includes, as this will slow down the build time of your site. For example, don't use includes every time you insert an image. (The above technique shows a use case for special images.)
### Passing parameter variables to includes
Suppose the parameter you want to pass to the include is a variable rather than a string. For example, you might be using {% raw %}`{{ site.product_name }}`{% endraw %} to refer to every instance of your product rather than the actual hard-coded name. (In this case, your `_config.yml` file would have a key called `product_name` with a value of your product's name.)
The string you pass to your include parameter can't contain curly braces. For example, you can't pass a parameter that contains this: {% raw %}`"The latest version of {{ site.product_name }} is now available."`{% endraw %}
If you want to include this variable in your parameter that you pass to an include, you need to store the entire parameter as a variable before passing it to the include. You can use `capture` tags to create the variable:
```liquid
{% raw %}{% capture download_note %}The latest version of
{{ site.product_name }} is now available.{% endcapture %}{% endraw %}
```
Then pass this captured variable into the parameter for the include. Omit the quotation marks around the parameter content because it's no longer a string (it's a variable):
```liquid
{% raw %}{% include note.html content=download_note %}{% endraw %}
```
### Passing references to YAML files as parameter values
Instead of passing string variables to the include, you can pass a reference to a YAML data file stored in the `_data` folder.
Here's an example. In the `_data` folder, suppose you have a YAML file called `profiles.yml`. Its content looks like this:
```yaml
- name: John Doe
login_age: old
image: johndoe.jpg
- name: Jane Doe
login_age: new
image: janedoe.jpg
```
In the `_includes` folder, assume you have a file called `spotlight.html` with this code:
```liquid
{% raw %}{% for person in include.participants %}
{% if person.login_age == "new" %}
{{ person.name }}
{% endif %}
{% endfor %}{% endraw %}
```
Now when you insert the `spotlight.html` include file, you can submit the YAML file as a parameter:
```
{% raw %}{% include spotlight.html participants=site.data.profiles %}{% endraw %}
```
In this instance, `site.data.profiles` gets inserted in place of {% raw %}`include.participants`{% endraw %} in the include file, and the Liquid logic processes. The result will be `Jane Doe`.

This site aims to be a comprehensive guide to Jekyll. Well cover topics such
as getting your site up and running, creating and managing your content,
customizing the way your site works and looks, deploying to various
environments, and give you some advice on participating in the future
development of Jekyll itself.
## So what is Jekyll, exactly?
Jekyll is a simple, blog-aware, static site generator. It takes a template
directory containing raw text files in various formats, runs it through
a converter (like [Markdown](https://daringfireball.net/projects/markdown/))
and our [Liquid](https://github.com/Shopify/liquid/wiki) renderer, and
spits out a complete, ready-to-publish static website suitable
for serving with your favorite web server. Jekyll also happens to be the engine
behind [GitHub Pages](https://pages.github.com), which means you can use Jekyll
to host your projects page, blog, or website from GitHubs servers **for
free**.
## Helpful Hints
Throughout this guide there are a number of small-but-handy pieces of
information that can make using Jekyll easier, more interesting, and less
hazardous. Heres what to look out for.

title: Installation
permalink: /docs/installation/
---
Getting Jekyll installed and ready-to-go should only take a few minutes.
If it ever becomes a pain, please [file an issue]({{ site.repository }}/issues/new)
(or submit a pull request) describing the issue you
encountered and how we might make the process easier.
### Requirements
Installing Jekyll should be straight-forward if all requirements are met.
Before you start, make sure your system has the following:
- GNU/Linux, Unix, or macOS
- [Ruby](https://www.ruby-lang.org/en/downloads/) version 2.1 or above, including all development
headers
- [RubyGems](https://rubygems.org/pages/download)
- [GCC](https://gcc.gnu.org/install/) and [Make](https://www.gnu.org/software/make/) (in case your system doesn't have them installed, which you can check by running `gcc -v` and `make -v` in your system's command line interface)
#### Only required for Jekyll 2 and earlier
- [NodeJS](https://nodejs.org/), or another JavaScript runtime (for CoffeeScript support).
- [Python 2.7](https://www.python.org/downloads/)
<div class="note info">
<h5>Problems installing Jekyll?</h5>
<p>
Check out the <a href="../troubleshooting/">troubleshooting</a> page or
<a href="{{ site.repository }}/issues/new">report an issue</a> so the
Jekyll community can improve the experience for everyone.
</p>
</div>
<div class="note info">
<h5>Running Jekyll on Windows</h5>
<p>
While Windows is not officially supported, it is possible to get Jekyll running
on Windows. Special instructions can be found on our
<a href="../windows/#installation">Windows-specific docs page</a>.
</p>
</div>
## Install with RubyGems
The best way to install Jekyll is via
[RubyGems](https://rubygems.org/pages/download). At the terminal prompt,
simply run the following command to install Jekyll:
```sh
$ gem install jekyll
```
All of Jekylls gem dependencies are automatically installed by the above
command, so you wont have to worry about them at all.
<div class="note info">
<h5>Installing Xcode Command-Line Tools</h5>
<p>
If you run into issues installing Jekyll's dependencies which make use of
native extensions and are using macOS, you will need to install Xcode
and the Command-Line Tools it ships with. Download them in
<code>Preferences &#8594; Downloads &#8594; Components</code>.
</p>
</div>
## Pre-releases
In order to install a pre-release, make sure you have all the requirements
installed properly and run:
```sh
gem install jekyll --pre
```
This will install the latest pre-release. If you want a particular pre-release,
use the `-v` switch to indicate the version you'd like to install:
```sh
gem install jekyll -v '2.0.0.alpha.1'
```
If you'd like to install a development version of Jekyll, the process is a bit
more involved. This gives you the advantage of having the latest and greatest,
but may be unstable.
```sh
$ git clone git://github.com/jekyll/jekyll.git
$ cd jekyll
$ script/bootstrap
$ bundle exec rake build
$ ls pkg/*.gem | head -n 1 | xargs gem install -l
```
## Optional Extras
There are a number of (optional) extra features that Jekyll supports that you
may want to install, depending on how you plan to use Jekyll. These extras
include LaTeX support, and the use of alternative content rendering engines.

## Already Have Jekyll?
Before you start developing with Jekyll, you may want to check that you're up to date with the latest version. To find your version of Jekyll, run one of these commands:
```sh
$ jekyll --version
$ gem list jekyll
```
You can also use [RubyGems](https://rubygems.org/gems/jekyll) to find the current versioning of any gem. But you can also use the `gem` command line tool:
```sh
$ gem search jekyll --remote
```
and you'll search for just the name `jekyll`, and in brackets will be latest version. Another way to check if you have the latest version is to run the command `gem outdated`. This will provide a list of all the gems on your system that need to be updated. If you aren't running the latest version, run this command:
```sh
$ gem update jekyll
```
Now that youve got everything up-to-date and installed, lets get to work!

title: Affinity Team Captains
---
**This guide is for affinity team captains.** These special people are **team maintainers** of one of our [affinity teams][] and help triage and evaluate the issues and contributions of others. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
## Affinity teams & their captains
The Jekyll project uses [affinity teams][] to help break up the work of incoming issues and pull requests from community members. We receive a sizeable number of issues and pull requests each week; the use of affinity teams helps distribute this load across a number of specialized groups instead of pushing it all onto @jekyll/core.
## Responsibilities of Team Captains
Each affinity team has a few captains who manage the issues and pull requests for that team. When an issue or PR is opened with a `/cc` for a given affinity team, @jekyllbot automatically assigns a random affinity team captain to the issue to triage it. They have access to add labels, reassign the issue, give LGTM's, and so forth. While they do not merge PR's today, they are still asked to review PR's for parts of the codebase under their purview.
## How do I become a team captain?
Just ask! Feel free to open an issue on `jekyll/jekyll` and add `/cc @jekyll/core`. We can add you. :smile:
Alternatively, you can email or otherwise reach out to [@parkr](https://github.com/parkr) directly if you prefer the more private route.
## Ugh, I'm tired and don't have time to be a captain anymore. What now?
No sweat at all! Email [@parkr](https://github.com/parkr) and ask to be removed. Alternatively, you should be able to go to your team's page on GitHub.com (go to https://github.com/jekyll, click "Teams", click the link to your team) and change your status to either "member" or leave the team.
We realize that being a captain is no easy feat so we want to make it a great experience. As always, communicate as much as you can with us about what is working, and what isn't. Thanks for dedicating some time to Jekyll! :sparkles:

title: "Avoiding Burnout"
---
**This guide is for maintainers.** These special people have **write access** to one or more of Jekyll's repositories and help merge the contributions of others. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
# 1. Use Jekyll
Maintainers of Jekyll should be using it regularly. This is partly because you won't be a good maintainer unless you can put yourself in the shoes of our users but also because you may decide to stop using Jekyll and at that point you should also decide not to be a maintainer and find other things to work on.
# 2. No Guilt About Leaving
All maintainers can stop working on Jekyll at any time without any guilt or explanation (like a job). We may still ask for your help with questions after you leave but you are under no obligation to answer them. Like a job, if you create a big mess and then leave you still have no obligations but we may think less of you (or, realistically, probably just revert the problematic work). Like a job, you should probably take a break from Jekyll at least a few times a year.
This also means contributors should be consumers. If a maintainer finds they are not using a project in the real-world, they should reconsider their involvement with the project.
# 3. Prioritise Maintainers Over Users
It's important to be user-focused but ultimately, as long as you follow #1 above, Jekyll's minimum number of users will be the number of maintainers. However, if Jekyll has no maintainers it will quickly become useless to all users and the project will die. As a result, no user complaint, behaviour or need takes priority over the burnout of maintainers. If users do not like the direction of the project, the easiest way to influence it is to make significant, high-quality code contributions and become a maintainer.
# 4. Learn To Say No
Jekyll gets a lot of feature requests, non-reproducible bug reports, usage questions and PRs we won't accept. These should be closed out as soon as we realise that they aren't going to be resolved or merged. This is kinder than deciding this after a long period of review. Our issue tracker should reflect work to be done.

title: "Becoming a Maintainer"
---
**This guide is for contributors.** These special people have contributed to one or more of Jekyll's repositories, but do not yet have write access to any. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
So you want to become a maintainer of a Jekyll project? We'd love to have you! Here are some things we like to see from community members before we promote them to maintainers.
## 1. Use Jekyll
You want to maintain Jekyll? Use it often. Do weird things with it. Do normal things with it. Does it work? Does it have any weaknesses? Is there a gap in the product that you think should be filled?
## 2. Help Triage Issues
Watch the repository you're interested in. Join [an Affinity Team](https://teams.jekyllrb.com) and receive mentions regarding a particular interest area of the project. When you receive a notification for an issue that has not been triaged by a maintainer, dive in. Can you reproduce the issue? Can you determine the fix? [More tips on Triaging an Issue in our maintainer guide](../triaging-an-issue). Every maintainer loves an issue that is resolved before they get to it. :smiley:
## 3. Write Documentation
Good documentation means less confusion for our users and fewer issues to triage. Documentation is always in need of fixes and updates as we change the code. Read through the documentation during your normal usage of the product and submit changes as you feel they are necessary.
## 4. Write Code
As a maintainer, you will be reviewing pull requests which update code. You should feel comfortable with the Jekyll codebase enough to confidently review any pull request put forward. In order to become more comfortable, write some code of your own and send a pull request. A great place to start is with any issue labeled "bug" in the issue tracker. Write a test which replicates the problem and fails, then work on fixing the code such that the test passes.
## 5. Review Pull Requests
Start by reviewing one pull request a week. Leave detailed comments and [follow our guide for reviewing pull requests](../reviewing-a-pull-request).
## 6. Ask!
Open an issue describing your contributions to the project and why you wish to be a maintainer. Issues are nice because you can easily reference where you have demonstrated that you help triage issues, write code & documentation, and review pull requests. You may also email any maintainer privately if you do not feel comfortable asking in the open.
We would love to expand the team and look forward to many more community members becoming maintainers!
# Helping Out Elsewhere
In addition to maintainers of our core and plugin code, the Jekyll team is comprised of moderators for our forums. These helpful community members take a look at the topics posted to [https://talk.jekyllrb.com](https://talk.jekyllrb.com) and ensure they are properly categorized and are acceptable under our Code of Conduct. If you would like to be a moderator, email one of the maintainers with links to where you have answered questions and a request to be added as a moderator. More help is always welcome.

**This guide is for maintainers.** These special people have **write access** to one or more of Jekyll's repositories and help merge the contributions of others. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
## Code Review
All pull requests should be subject to code review. Code review is a [foundational value](https://blog.fullstory.com/what-we-learned-from-google-code-reviews-arent-just-for-catching-bugs-b125a13aa292) of good engineering teams. Besides providing validation of correctness, it promotes a sense of community and gives other maintainers understanding of all parts of the code base. In short, code review is crucial to a healthy open source project.
**Read our guide for [Reviewing a pull request](../reviewing-a-pull-request) before merging.** Notably, the change must have tests if for code, and at least two maintainers must give it an OK.
## Merging
We have [a helpful little bot](https://github.com/jekyllbot) which we use to merge pull requests. We don't use the GitHub.com interface for two reasons:
1. You can't modify anything on mobile (e.g. titles, labels)
2. Provide a consistent paper trail in the `History.markdown` file for each release
To merge a pull request, leave a comment thanking the contributor, then add the special merge request:
```text
Thank you very much for your contribution. Folks like you make this project and community strong. :heart:
@jekyllbot: merge +dev
```
The merge request is made up of three things:
1. `@jekyllbot:` this is the prefix our bot looks for when processing commands
2. `merge` the command
3. `+dev` the category to which the changes belong
The categories match the H3's in the history/changelog file, and they are:
1. Major Enhancements (`+major`) major updates or breaking changes to the code which necessitate a major version bump (v3 ~> v4)
2. Minor Enhancements (`+minor`) minor updates (feature, enhancement) which necessitate a minor version bump (v3.1 ~> v3.2)
3. Bug Fixes (`+bug`) corrections to code which do not change or add functionality, which necessitate a patch version bump (v3.1.0 ~> v3.1.1)
4. Documentation (`+doc`) - changes to the documentation found in `docs/_docs/`
5. Site Enhancements (`+site`) changes to the source of [https://jekyllrb.com](https://jekyllrb.com) found in `docs/`
6. Development Fixes (`+dev`) changes which do not affect user-facing functionality or documentation, such as test fixes or bumping internal dependencies
7. Forward Ports (`+port`) — bug fixes applied to a previous version of Jekyll pulled onto `master`, e.g. cherry-picked commits from `3-1-stable` to `master`
Once @jekyllbot has merged the pull request, you should see three things:
1. A successful merge
2. Addition of labels for the necessary category if they aren't already applied
3. A commit to the `History.markdown` file which adds a note about the change
If you forget the category, that's just fine. You can always go back and move the line to the proper category header later. The category is always necessary for `jekyll/jekyll`, but many plugins have too few changes to necessitate changelog categories.
## Rejoice
You did it! Thanks for being a maintainer for one of our official Jekyll projects. Your work means the world to our thousands of users who rely on Jekyll daily. :heart:

## Respond Kindly
Above all else, please review a pull request kindly. Our community can only be strong if we make it a welcoming and inclusive environment. To further promote this, the Jekyll community is governed by a [Code of Conduct](/docs/conduct/) by which all community members must abide.
Use emoji liberally :heart: :tada: :sparkles: :confetti_ball: and feel free to be emotive!! Contributions keep this project moving forward and we're always happy to receive them, even if the pull request isn't ultimately merged.
Mike McQuaid's post on the GitHub blog entitled ["Kindly Closing Pull Requests"](https://github.com/blog/2124-kindly-closing-pull-requests) is a great place to start. It describes various scenarios in which it would be acceptable to close a pull request for reasons other than lack of technical integrity or accuracy. Part of being kind is responding to and resolving pull requests quickly.
## Respond Quickly
We should be able to review all pull requests within one week. The only time initial review should take longer is if all the maintainers mysteriously took vacation during the same week. Promptness encourages frequent, high-quality contributions from community members and other maintainers.
If your response requires a response on the part of the author, please add the `pending-feedback` tag. @jekyllbot will automatically remove the tag once the author of the pull request responds.
## Resolve Quickly
Similarly, we should aim to resolve pull requests quickly. If a pull request introduces a feature which does not fit into the core purpose or goal of the project, close it promptly with a kind explanation of why it is not acceptable.
Leave detailed comments wherever possible. Provide the contributor with context around why the change you are requesting is necessary, or why the question you are asking is important to resolve. The more context we can clearly communicate to the contributor, the better able the contributor is to provide high-quality patches.
You may close a pull request if more than 30 days pass without a response from the author.
In some cases, review will involve many weeks of back-and-forth. As long as communication continues, this is fine. Ideally, any PR would be capable of resolution within 30 days of it being opened.
## Look for Tests
If this is a code change, are there tests for the updated or added behaviour? Shipping a version with bugs is inevitable, but ensuring changes are tested helps keep bugs and regressions to a minimum.
## CI Must Pass
It is fine to ask a contributor to investigate failures on Travis and patch them up before you begin your review. It is helpful to leave a message for the contributor indicating that the tests have failed and that no review will occur before the tests pass. If they ask for help, take a look and assist if you can.
## Rule of Two
A pull request may be merged once two maintainers have reviewed the pull request and indicated that it is acceptable to them. There is no need to wait for a third unless one of the two reviewers wishes for another set of eyes.
## Think Security
We owe it to our users to ensure that using a theme from the community or building someone else's site doesn't come with built-in security vulnerabilities. Things like where files may be read from and written to are important to keep secure. Jekyll is also the basis for hosted services such as [GitHub Pages](https://pages.github.com), which cannot upgrade when security issues are introduced.

title: "Special Labels"
---
**This guide is for maintainers.** These special people have **write access** to one or more of Jekyll's repositories and help merge the contributions of others. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
We use a series of "special labels" on GitHub.com to automate handling of some parts of the pull request and issue process. @jekyllbot may automatically apply or remove certain labels based on actions taken by users or maintainers. Below are the labels and how they work:
## `pending-feedback`
This label is used to indicate that we need more information from the issue/PR author in order to continue. It may be that you need more info before you can properly triage a bug report, or that you have some unanswered questions about a PR that need to be resolved before moving forward. You can safely ignore any issue with this label, as it is waiting for feedback.
## `needs-work` & `pending-rebase`
These labels are used to indicate that the Git state of a pull request must change. Both are removed once a push is registered (a "synchronize" event for the pull request) and the pull request becomes mergable. Add `needs-work` to a PR if, after your review, it requires code changes. Add `pending-rebase` to a PR if the code is fine but the branch is not automatically mergable with the target branch (e.g. `master`).
## `stale`
This label is automatically added and removed by @jekyllbot based on activity on an issue or pull request. The rules for this label are laid out in [Triaging an Issue: Staleness and automatic closure](../triaging-an-issue/#staleness-and-automatic-closure).
## `pinned`
This label is for @jekyllbot to ignore the age of the issue, which means that the `stale` label won't be automatically added, and the issue won't be closed after a while. This needs to be set manually, and should be set with care. (The `has-pull-request` label does the same thing, but shouldn't be used to _only_ keep an issue open)

title: "Triaging an Issue"

**This guide is for maintainers.** These special people have **write access** to one or more of Jekyll's repositories and help merge the contributions of others. You may find what is written here interesting, but its definitely not for everyone.
{: .note .info }
Before evaluating an issue, it is important to identify if it is a feature
request or a bug. For the Jekyll project the following definitions are used
to identify a feature or a bug:
**Feature** - A feature is defined as a request that adds functionality to
Jekyll outside of its current capabilities.
**Bug** - A bug is defined as an issue that identifies an error that a user
(or users) encounter when using current Jekyll functionalities.
## Feature?
If the issue describes a feature request, ask:
1. Is this a setting? [Settings are a crutch](http://ben.balter.com/2016/03/08/optimizing-for-power-users-and-edge-cases/#settings-are-a-crutch) for doing "the right thing". Settings usually point to a bad default or an edge case that could be solved easily with a plugin. Keep the :christmas_tree: of settings as small as possible so as not to reduce the usability of the product. We like the philosophy "decisions not options."
2. Would at least 80% of users find it useful? If even a quarter of our users won't use it, it's very likely that the request doesn't fit our product's core goal.
3. Is there another way to accomplish the end goal of the request? Most feature requests are due to bad documentation for or understanding of a pre-existing feature. See if you can clarify the end goal of the request. What is the user trying to do? Could they accomplish that goal through another feature we already support?
4. Even if 80% of our users will use it, does it fit the core goal of our project? We are writing a tool for making static websites, not a swiss army knife for publishing more generally.
Feel free to get others' opinions and ask questions of the issue author, but depending upon the answers to the questions above, it may be out of scope for our project.
If the request is within scope, prioritize it on the product roadmap with the other maintainers. Apply the appropriate tags and ensure the right people have weighed in to define the feature's scope and implementation. If you want to be the _best ever_, submit a PR yourself which adds the feature.
## Bug?
### Reproducibility
If the bug has clear reproduction steps, take a minute to try them. If it helps, write a test in our test suite for the scenario which replicates the problem. Can you reliably replicate the issue?
If you can't replicate the issue, post your replication steps which didn't work and ask for clarification from the issue author.
### Supported Platform
Is the author using a supported platform? We support the latest versions of macOS, Ubuntu, Debian, CentOS, Fedora, and Arch Linux.
You may close the issue immediately if the author cannot reproduce the issue on a supported platform. For Windows-related problems, leave a comment letting the user know that Windows is not officially supported, but that they may absolutely continue using the issue to communicate with folks from `@jekyll/windows` to further investigate. Additionally, you can point them to Jekyll Talk (https://talk.jekyllrb.com) as a means of getting support from the community.
If the user is experiencing issues with GitHub Pages or another hosted platform that we cannot reproduce, please direct them to the platform's support channel and close the issue.
### What they wanted vs. what they got
An issue without a clear explanation of what the user got and what they were expecting to get is not an issue we can accurately respond to. If the user doesn't provide this information, please ask for clarification and apply the `pending-feedback` label. This information helps us build test cases such that we do not break the behaviour again in the future. The `pending-feedback` label will be removed automatically once the issue author posts a reply.
Is what they wanted to get something we want to happen? Sometimes a bug report is actually masquerading as a feature request. See the guidance above for handling feature requests.
### Staleness and automatic closure
@jekyllbot will automatically mark issues as `stale` if no activity occurs for at least one month. @jekyllbot leaves a comment asking for information about reproducibility in current versions. If no one responds after another month, the issue is automatically closed. This behaviour can be suppressed by setting the [`pinned` label](../maintaining/special-labels.md/#pinned).

title: Creating pages
permalink: /docs/pages/
---
In addition to [writing posts](../posts/), you might also want to add static pages (content that isn't date-based) to your Jekyll site. By taking advantage of the way Jekyll copies files and directories, this is easy to do.
## Homepage
Just about every web server configuration you come across will look for an HTML
file called `index.html` (by convention) in the site's root folder and display
that as the homepage. Unless the web server youre using is configured to look
for some different filename as the default, this file will turn into the
homepage of your Jekyll-generated site.
<div class="note">
<h5>ProTip™: Use layouts on your homepage</h5>
<p>
Any HTML file on your site can use layouts and/or includes, even the
homepage. Common content, like headers and footers, make excellent
candidates for extraction into a layout.
</p>
</div>
## Where additional pages live
Where you put HTML or [Markdown](https://daringfireball.net/projects/markdown/)
files for pages depends on how you want the pages to work. There are two main ways of creating pages:
- Place named HTML or [Markdown](https://daringfireball.net/projects/markdown/)
files for each page in your site's root folder.
- Place pages inside folders and subfolders named whatever you want.
Both methods work fine (and can be used in conjunction with each other),
with the only real difference being the resulting URLs. By default, pages retain the same folder structure in `_site` as they do in the source directory.
### Named HTML files
The simplest way of adding a page is just to add an HTML file in the root
directory with a suitable name for the page you want to create. For a site with
a homepage, an about page, and a contact page, heres what the root directory
and associated URLs might look like:
```sh
.
|-- _config.yml
|-- _includes/
|-- _layouts/
|-- _posts/
|-- _site/
|-- about.html # => http://example.com/about.html
|-- index.html # => http://example.com/
|-- other.md # => http://example.com/other.html
└── contact.html # => http://example.com/contact.html
```
If you have a lot of pages, you can organize those pages into subfolders. The same subfolders that are used to group your pages in our project's source will exist in the `_site` folder when your site builds.
## Flattening pages from subfolders into the root directory
If you have pages organized into subfolders in your source folder and want to flatten them in the root folder on build, you must add the [permalink]({% link _docs/permalinks.md %}) property directly in your page's front matter like this:
```
---
title: My page
permalink: mypageurl.html
---
```
### Named folders containing index HTML files
If you don't want file extensions (`.html`) to appear in your page URLs (file extensions are the default), you can choose a [permalink style](../permalinks/#builtinpermalinkstyles) that has a trailing slash instead of a file extension.
Note if you want to view your site offline *without the Jekyll preview server*, your browser will need the file extension to display the page, and all assets will need to be relative links that function without the server baseurl.

title: Pagination
permalink: /docs/pagination/
---
With many websites &mdash; especially blogs &mdash; its very common to
break the main listing of posts up into smaller lists and display them over
multiple pages. Jekyll offers a pagination plugin, so you can automatically
generate the appropriate files and folders you need for paginated listings.
For Jekyll 3, include the `jekyll-paginate` plugin in your Gemfile and in
your `_config.yml` under `gems`. For Jekyll 2, this is standard.
<div class="note info">
<h5>Pagination only works within HTML files</h5>
<p>
Pagination does not work from within Markdown or Textile files from
your Jekyll site. Pagination works when called from within the HTML
file, named <code>index.html</code>, which optionally may reside in and
produce pagination from within a subdirectory, via the
<code>paginate_path</code> configuration value.
</p>
</div>
## Enable pagination
To enable pagination for your blog, add a line to the `_config.yml` file that
specifies how many items should be displayed per page:
```yaml
paginate: 5
```
The number should be the maximum number of Posts youd like to be displayed
per-page in the generated site.
You may also specify the destination of the pagination pages:
```yaml
paginate_path: "/blog/page:num/"
```
This will read in `blog/index.html`, send it each pagination page in Liquid as
`paginator` and write the output to `blog/page:num/`, where `:num` is the
pagination page number, starting with `2`. If a site has 12 posts and specifies
`paginate: 5`, Jekyll will write `blog/index.html` with the first 5 posts, `blog/page2/index.html` with the next 5 posts
and `blog/page3/index.html` with the last 2 posts into the destination
directory.
<div class="note warning">
<h5>Don't set a permalink</h5>
<p>
Setting a permalink in the front matter of your blog page will cause
pagination to break. Just omit the permalink.
</p>
</div>
## Liquid Attributes Available
The pagination plugin exposes the `paginator` liquid object with the following
attributes:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Attribute</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><p><code>page</code></p></td>
<td><p>current page number</p></td>

<tr>
<td><p><code>next_page_path</code></p></td>
<td>
<p>
path of next pagination page,
or <code>nil</code> if no subsequent page exists
</p>
</td>
</tr>
</tbody>
</table>
</div>
<div class="note info">
<h5>Pagination does not support tags or categories</h5>
<p>Pagination pages through every post in the <code>posts</code>
variable unless a post has <code>hidden: true</code> in its YAML Front Matter.
It does not currently allow paging over groups of posts linked
by a common tag or category. It cannot include any collection of
documents because it is restricted to posts.</p>
</div>
## Render the paginated Posts
The next thing you need to do is to actually display your posts in a list using
the `paginator` variable that will now be available to you. Youll probably
want to do this in one of the main pages of your site. Heres one example of a
simple way of rendering paginated Posts in a HTML file:
```html
{% raw %}
---
layout: default
title: My Blog
---
<!-- This loops through the paginated posts -->
{% for post in paginator.posts %}
<h1><a href="{{ post.url }}">{{ post.title }}</a></h1>
<p class="author">
<span class="date">{{ post.date }}</span>
</p>
<div class="content">
{{ post.content }}
</div>
{% endfor %}
<!-- Pagination links -->
<div class="pagination">
{% if paginator.previous_page %}
<a href="{{ paginator.previous_page_path }}" class="previous">Previous</a>
{% else %}
<span class="previous">Previous</span>
{% endif %}
<span class="page_number ">Page: {{ paginator.page }} of {{ paginator.total_pages }}</span>
{% if paginator.next_page %}
<a href="{{ paginator.next_page_path }}" class="next">Next</a>
{% else %}
<span class="next ">Next</span>
{% endif %}
</div>
{% endraw %}
```
<div class="note warning">
<h5>Beware the page one edge-case</h5>
<p>
Jekyll does not generate a page1 folder, so the above code will not work
when a <code>/page1</code> link is produced. See below for a way to handle
this if its a problem for you.
</p>
</div>
The following HTML snippet should handle page one, and render a list of each
page with links to all but the current page.
```html
{% raw %}
{% if paginator.total_pages > 1 %}
<div class="pagination">
{% if paginator.previous_page %}
<a href="{{ paginator.previous_page_path | prepend: site.baseurl | replace: '//', '/' }}">&laquo; Prev</a>
{% else %}
<span>&laquo; Prev</span>
{% endif %}
{% for page in (1..paginator.total_pages) %}
{% if page == paginator.page %}
<em>{{ page }}</em>
{% elsif page == 1 %}
<a href="{{ paginator.previous_page_path | prepend: site.baseurl | replace: '//', '/' }}">{{ page }}</a>
{% else %}
<a href="{{ site.paginate_path | prepend: site.baseurl | replace: '//', '/' | replace: ':num', page }}">{{ page }}</a>

title: Permalinks
permalink: /docs/permalinks/
---
Permalinks refer to the URLs (excluding the domain name or directory folder) for your pages, posts, or collections.
Jekyll supports a flexible way to build permalinks, allowing you to leverage various template variables or choose built-in permalink styles (such as `date`) that automatically use a template-variable pattern.
You construct permalinks by creating a template URL where dynamic elements are represented by colon-prefixed keywords. The default template permalink is `/:categories/:year/:month/:day/:title.html`. Each of the colon-prefixed keywords is a template variable.
## Where to configure permalinks
You can configure your site's permalinks through the [Configuration]({% link _docs/configuration.md %}) file or in the [Front Matter]({% link _docs/frontmatter.md %}) for each post, page, or collection.
Setting permalink styles in your configuration file applies the setting globally in your project. You configure permalinks in your `_config.yml` file like this:
```yaml
permalink: /:categories/:year/:month/:day/:title.html
```
If you don't specify any permalink setting, Jekyll uses the above pattern as the default.
The permalink can also be set using a built-in permalink style:
```yaml
permalink: date
```
`date` is the same as `:categories/:year/:month/:day/:title.html`, the default. See [Built-in Permalink Styles](#builtinpermalinkstyles) below for more options.
Setting the permalink in your post, page, or collection's front matter overrides any global settings. Here's an example:
```yaml
---
title: My page title
permalink: /mypageurl/
---
```
Even if your configuration file specifies the `date` style, the URL for this page would be `http://somedomain.com/mypageurl/`.
When you use permalinks that omit the `.html` file extension (called "pretty URLs") Jekyll builds the file as index.html placed inside a folder with the page's name. For example:
```
├── mypageurl
│   └── index.html
```
With a URL such as `/mypageurl/`, servers automatically load the index.html file inside the folder, so users can simply navigate to `http://somedomain.com/mypageurl/` to get to `mypageurl/index.html`.
## Template variables for permalinks {#template-variables}
The following table lists the template variables available for permalinks. You can use these variables in the `permalink` property in your config file.
<div class="mobile-side-scroller">
<table>
<thead>
<tr>

</p>
</td>
</tr>
<tr>
<td>
<p><code>categories</code></p>
</td>
<td>
<p>
The specified categories for this post. If a post has multiple
categories, Jekyll will create a hierarchy (e.g. <code>/category1/category2</code>).
Also Jekyll automatically parses out double slashes in the URLs,
so if no categories are present, it will ignore this.
</p>
</td>
</tr>
</tbody>
</table>
</div>
Note that all template variables relating to time or categories are available to posts only.
## Built-in permalink styles {#builtinpermalinkstyles}
Although you can specify a custom permalink pattern using [template variables](#template-variables), Jekyll also provides the following built-in styles for convenience.
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Permalink Style</th>
<th>URL Template</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>date</code></p>
</td>
<td>
<p><code>/:categories/:year/:month/:day/:title.html</code></p>
</td>
</tr>
<tr>
<td>
<p><code>pretty</code></p>
</td>
<td>
<p><code>/:categories/:year/:month/:day/:title/</code></p>
</td>
</tr>
<tr>
<td>
<p><code>ordinal</code></p>
</td>
<td>
<p><code>/:categories/:year/:y_day/:title.html</code></p>
</td>
</tr>
<tr>
<td>
<p><code>none</code></p>
</td>
<td>
<p><code>/:categories/:title.html</code></p>
</td>
</tr>
</tbody>
</table>
</div>
Rather than typing `permalink: /:categories/:year/:month/:day/:title/`, you can just type `permalink: pretty`.
<div class="note info">
<h5>Specifying permalinks through the YAML Front Matter</h5>
<p>Built-in permalink styles are not recognized in YAML Front Matter. As a result, <code>permalink: pretty</code> will not work.</p>
</div>
## Permalink style examples with posts {#permalink-style-examples}
Here are a few examples to clarify how permalink styles get applied with posts.
Given a post named: `/2009-04-29-slap-chop.md`
<div class="mobile-side-scroller">

</div>
## Permalink settings for pages and collections {#pages-and-collections}
The permalink setting in your configuration file specifies the permalink style used for posts, pages, and collections. However, because pages and collections don't have time or categories, these aspects of the permalink style are ignored with pages and collections.
For example:
* A permalink style of `/:categories/:year/:month/:day/:title.html` for posts becomes `/:title.html` for pages and collections.
* A permalink style of `pretty` (or `/:categories/:year/:month/:day/:title/`), which omits the file extension and contains a trailing slash, will update page and collection permalinks to also omit the file extension and contain a trailing slash: `/:title/`.
* A permalink style of `date`, which contains a trailing file extension, will update page permalinks to also contain a trailing file extension: `/:title.html`. But no time or category information will be included.
## Permalinks and default paths
The path to the post or page in the built site differs for posts, pages, and collections:
### Posts
The subfolders into which you may have organized your posts inside the `_posts` directory will not be part of the permalink.
If you use a permalink style that omits the `.html` file extension, each post is rendered as an `index.html` file inside a folder with the post's name (for example, `categoryname/2016/12/01/mypostname/index.html`).
### Pages
Unlike posts, pages by default mimic the source directory structure exactly. (The only exception is if your page has a `permalink` declared its front matter &mdash; in that case, the structure honors the permalink setting instead of the source folder structure.)
As with posts, if you use a permalink style that omits the `.html` file extension, each page is rendered as an `index.html` file inserted inside a folder with the page's name (for example, `mypage/index.html`).
### Collections
By default, collections follow a similar structure in the `_site` folder as pages, except that the path is prefaced by the collection name. For example: `collectionname/mypage.html`. For permalink settings that omit the file extension, the path would be `collection_name/mypage/index.html`.
Collections have their own way of setting permalinks. Additionally, collections have unique template variables available available (such as `path` and `output_ext`). See the [Configuring permalinks for collections](../collections/#permalinks) in Collections for more information.
## Flattening pages in \_site on build
If you want to flatten your pages (pull them out of subfolders) in the `_site` directory when your site builds (similar to posts), add the `permalink` property to the front matter of each page, with no path specified:
```
---
title: My page
permalink: mypageurl.html
---
```
## Extensionless permalinks with no trailing slashes {#extensionless-permalinks}
Jekyll supports permalinks that contain neither a trailing slash nor a file extension, but this requires additional support from the web server to properly serve. When using these types of permalinks, output files written to disk will still have the proper file extension (typically `.html`), so the web server must be able to map requests without file extensions to these files.
Both [GitHub Pages](../github-pages/) and the Jekyll's built-in WEBrick server handle these requests properly without any additional work.
### Apache
The Apache web server has extensive support for content negotiation and can handle extensionless URLs by setting the [multiviews](https://httpd.apache.org/docs/current/content-negotiation.html#multiviews) option in your `httpd.conf` or `.htaccess` file:
{% highlight apache %}
Options +MultiViews
{% endhighlight %}
### Nginx
The [try_files](http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files) directive allows you to specify a list of files to search for to process a request. The following configuration will instruct nginx to search for a file with an `.html` extension if an exact match for the requested URI is not found.
{% highlight nginx %}
try_files $uri $uri.html $uri/ =404;
{% endhighlight %}
## Linking without regard to permalink styles
You can create links in your topics to other posts, pages, or collection items in a way that is valid no matter what permalink configuration you choose. By using the `link` tag, if you change your permalinks, your links won't break. See [Linking to pages](../templates#link) in Templates for more details.

title: Plugins
permalink: /docs/plugins/
---
Jekyll has a plugin system with hooks that allow you to create custom generated
content specific to your site. You can run custom code for your site without
having to modify the Jekyll source itself.
<div class="note info">
<h5>Plugins on GitHub Pages</h5>
<p>
<a href="https://pages.github.com/">GitHub Pages</a> is powered by Jekyll.
However, all Pages sites are generated using the <code>--safe</code> option
to disable custom plugins for security reasons. Unfortunately, this means
your plugins wont work if youre deploying to GitHub Pages.<br><br>
You can still use GitHub Pages to publish your site, but youll need to
convert the site locally and push the generated static files to your GitHub
repository instead of the Jekyll source files.
</p>
</div>
## Installing a plugin
You have 3 options for installing plugins:
1. In your site source root, make a `_plugins` directory. Place your plugins
here. Any file ending in `*.rb` inside this directory will be loaded before
Jekyll generates your site.
2. In your `_config.yml` file, add a new array with the key `plugins` and the
values of the gem names of the plugins you'd like to use. An example:
plugins: [jekyll-coffeescript, jekyll-watch, jekyll-assets]
# This will require each of these plugins automatically.
Then install your plugins using `gem install jekyll-coffeescript jekyll-watch jekyll-assets`
3. Add the relevant plugins to a Bundler group in your `Gemfile`. An
example:
group :jekyll_plugins do
gem "my-jekyll-plugin"
gem "another-jekyll-plugin"
end
Now you need to install all plugins from your Bundler group by running single command `bundle install`
<div class="note info">
<h5>
<code>_plugins</code>, <code>_config.yml</code> and <code>Gemfile</code>
can be used simultaneously
</h5>
<p>
You may use any of the aforementioned plugin options simultaneously in the
same site if you so choose. Use of one does not restrict the use of the
others.
</p>
</div>
In general, plugins you make will fall into one of five categories:
1. [Generators](#generators)
2. [Converters](#converters)
3. [Commands](#commands)
4. [Tags](#tags)
5. [Hooks](#hooks)
## Generators
You can create a generator when you need Jekyll to create additional content
based on your own rules.
A generator is a subclass of `Jekyll::Generator` that defines a `generate`
method, which receives an instance of
[`Jekyll::Site`]({{ site.repository }}/blob/master/lib/jekyll/site.rb). The
return value of `generate` is ignored.
Generators run after Jekyll has made an inventory of the existing content, and
before the site is generated. Pages with YAML Front Matters are stored as
instances of
[`Jekyll::Page`]({{ site.repository }}/blob/master/lib/jekyll/page.rb)
and are available via `site.pages`. Static files become instances of
[`Jekyll::StaticFile`]({{ site.repository }}/blob/master/lib/jekyll/static_file.rb)
and are available via `site.static_files`. See
[the Variables documentation page](/docs/variables/) and
[`Jekyll::Site`]({{ site.repository }}/blob/master/lib/jekyll/site.rb)
for more details.
For instance, a generator can inject values computed at build time for template
variables. In the following example the template `reading.html` has two
variables `ongoing` and `done` that we fill in the generator:
```ruby
module Reading
class Generator < Jekyll::Generator
def generate(site)
ongoing, done = Book.all.partition(&:ongoing?)
reading = site.pages.detect {|page| page.name == 'reading.html'}
reading.data['ongoing'] = ongoing
reading.data['done'] = done
end
end
end
```
This is a more complex generator that generates new pages:
```ruby
module Jekyll
class CategoryPage < Page
def initialize(site, base, dir, category)
@site = site
@base = base
@dir = dir
@name = 'index.html'
self.process(@name)
self.read_yaml(File.join(base, '_layouts'), 'category_index.html')
self.data['category'] = category
category_title_prefix = site.config['category_title_prefix'] || 'Category: '
self.data['title'] = "#{category_title_prefix}#{category}"
end
end
class CategoryPageGenerator < Generator
safe true
def generate(site)
if site.layouts.key? 'category_index'
dir = site.config['category_dir'] || 'categories'
site.categories.each_key do |category|
site.pages << CategoryPage.new(site, site.source, File.join(dir, category), category)
end
end
end
end
end
```
In this example, our generator will create a series of files under the
`categories` directory for each category, listing the posts in each category
using the `category_index.html` layout.
Generators are only required to implement one method:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Method</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>generate</code></p>
</td>
<td>
<p>Generates content as a side-effect.</p>
</td>
</tr>
</tbody>
</table>
</div>
## Converters
If you have a new markup language youd like to use with your site, you can
include it by implementing your own converter. Both the Markdown and
[Textile](https://github.com/jekyll/jekyll-textile-converter) markup
languages are implemented using this method.
<div class="note info">
<h5>Remember your YAML Front Matter</h5>
<p>
Jekyll will only convert files that have a YAML header at the top, even for
converters you add using a plugin.
</p>
</div>
Below is a converter that will take all posts ending in `.upcase` and process
them using the `UpcaseConverter`:
```ruby
module Jekyll
class UpcaseConverter < Converter
safe true
priority :low
def matches(ext)
ext =~ /^\.upcase$/i
end
def output_ext(ext)
".html"
end
def convert(content)
content.upcase
end
end
end
```
Converters should implement at a minimum 3 methods:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Method</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>matches</code></p>
</td>
<td><p>
Does the given extension match this converters list of acceptable
extensions? Takes one argument: the files extension (including the
dot). Must return <code>true</code> if it matches, <code>false</code>
otherwise.
</p></td>
</tr>
<tr>
<td>
<p><code>output_ext</code></p>
</td>
<td><p>
The extension to be given to the output file (including the dot).
Usually this will be <code>".html"</code>.
</p></td>
</tr>
<tr>
<td>
<p><code>convert</code></p>
</td>
<td><p>
Logic to do the content conversion. Takes one argument: the raw content
of the file (without YAML Front Matter). Must return a String.
</p></td>
</tr>
</tbody>
</table>
</div>
In our example, `UpcaseConverter#matches` checks if our filename extension is
`.upcase`, and will render using the converter if it is. It will call
`UpcaseConverter#convert` to process the content. In our simple converter were
simply uppercasing the entire content string. Finally, when it saves the page,
it will do so with a `.html` extension.
## Commands
As of version 2.5.0, Jekyll can be extended with plugins which provide
subcommands for the `jekyll` executable. This is possible by including the
relevant plugins in a `Gemfile` group called `:jekyll_plugins`:
```ruby
group :jekyll_plugins do
gem "my_fancy_jekyll_plugin"
end
```
Each `Command` must be a subclass of the `Jekyll::Command` class and must
contain one class method: `init_with_program`. An example:
```ruby
class MyNewCommand < Jekyll::Command
class << self
def init_with_program(prog)
prog.command(:new) do |c|
c.syntax "new [options]"
c.description 'Create a new Jekyll site.'
c.option 'dest', '-d DEST', 'Where the site should go.'
c.action do |args, options|
Jekyll::Site.new_site_at(options['dest'])
end
end
end
end
end
```
Commands should implement this single class method:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Method</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>init_with_program</code></p>
</td>
<td><p>
This method accepts one parameter, the
<code><a href="https://github.com/jekyll/mercenary#readme">Mercenary::Program</a></code>
instance, which is the Jekyll program itself. Upon the program,
commands may be created using the above syntax. For more details,
visit the Mercenary repository on GitHub.com.
</p></td>
</tr>
</tbody>
</table>
</div>
## Tags
If youd like to include custom liquid tags in your site, you can do so by
hooking into the tagging system. Built-in examples added by Jekyll include the
`highlight` and `include` tags. Below is an example of a custom liquid tag that
will output the time the page was rendered:
```ruby
module Jekyll
class RenderTimeTag < Liquid::Tag
def initialize(tag_name, text, tokens)
super
@text = text
end
def render(context)
"#{@text} #{Time.now}"
end
end
end
Liquid::Template.register_tag('render_time', Jekyll::RenderTimeTag)
```
At a minimum, liquid tags must implement:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Method</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>render</code></p>
</td>
<td>
<p>Outputs the content of the tag.</p>
</td>
</tr>
</tbody>
</table>
</div>
You must also register the custom tag with the Liquid template engine as
follows:
```ruby
Liquid::Template.register_tag('render_time', Jekyll::RenderTimeTag)
```
In the example above, we can place the following tag anywhere in one of our
pages:
```ruby
{% raw %}
<p>{% render_time page rendered at: %}</p>
{% endraw %}
```
And we would get something like this on the page:
```html
<p>page rendered at: Tue June 22 23:38:47 0500 2010</p>
```
### Liquid filters
You can add your own filters to the Liquid template system much like you can
add tags above. Filters are simply modules that export their methods to liquid.
All methods will have to take at least one parameter which represents the input
of the filter. The return value will be the output of the filter.
```ruby
module Jekyll
module AssetFilter
def asset_url(input)
"http://www.example.com/#{input}?#{Time.now.to_i}"
end
end
end
Liquid::Template.register_filter(Jekyll::AssetFilter)
```
<div class="note">
<h5>ProTip™: Access the site object using Liquid</h5>
<p>
Jekyll lets you access the <code>site</code> object through the
<code>context.registers</code> feature of Liquid at <code>context.registers[:site]</code>. For example, you can
access the global configuration file <code>_config.yml</code> using
<code>context.registers[:site].config</code>.
</p>
</div>
### Flags
There are two flags to be aware of when writing a plugin:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Flag</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>safe</code></p>
</td>
<td>
<p>
A boolean flag that informs Jekyll whether this plugin may be safely
executed in an environment where arbitrary code execution is not
allowed. This is used by GitHub Pages to determine which core plugins
may be used, and which are unsafe to run. If your plugin does not
allow for arbitrary code execution, set this to <code>true</code>.
GitHub Pages still wont load your plugin, but if you submit it for
inclusion in core, its best for this to be correct!
</p>
</td>
</tr>
<tr>
<td>
<p><code>priority</code></p>
</td>
<td>
<p>
This flag determines what order the plugin is loaded in. Valid values
are: <code>:lowest</code>, <code>:low</code>, <code>:normal</code>,
<code>:high</code>, and <code>:highest</code>. Highest priority
matches are applied first, lowest priority are applied last.
</p>
</td>
</tr>
</tbody>
</table>
</div>
To use one of the example plugins above as an illustration, here is how youd
specify these two flags:
```ruby
module Jekyll
class UpcaseConverter < Converter
safe true
priority :low
...
end
end
```
## Hooks
Using hooks, your plugin can exercise fine-grained control over various aspects
of the build process. If your plugin defines any hooks, Jekyll will call them
at pre-defined points.
Hooks are registered to a container and an event name. To register one, you
call Jekyll::Hooks.register, and pass the container, event name, and code to
call whenever the hook is triggered. For example, if you want to execute some
custom functionality every time Jekyll renders a post, you could register a
hook like this:
```ruby
Jekyll::Hooks.register :posts, :post_render do |post|
# code to call after Jekyll renders a post
end
```
Jekyll provides hooks for <code>:site</code>, <code>:pages</code>,
<code>:posts</code>, and <code>:documents</code>. In all cases, Jekyll calls
your hooks with the container object as the first callback parameter. However,
all `:pre_render` hooks and the`:site, :post_render` hook will also provide a
payload hash as a second parameter. In the case of `:pre_render`, the payload
gives you full control over the variables that are available while rendering.
In the case of `:site, :post_render`, the payload contains final values after
rendering all the site (useful for sitemaps, feeds, etc).
The complete list of available hooks is below:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Container</th>
<th>Event</th>
<th>Called</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<p><code>:site</code></p>
</td>
<td>
<p><code>:after_init</code></p>
</td>
<td>
<p>Just after the site initializes, but before setup & render. Good
for modifying the configuration of the site.</p>

title: Writing posts
permalink: /docs/posts/
---
One of Jekylls best aspects is that it is “blog aware”. What does this mean,
exactly? Well, simply put, it means that blogging is baked into Jekylls
functionality. If you write articles and publish them online, you can publish
and maintain a blog simply by managing a folder of text-files on your computer.
Compared to the hassle of configuring and maintaining databases and web-based
CMS systems, this will be a welcome change!
## The Posts Folder
As explained on the [directory structure](../structure/) page, the `_posts`
folder is where your blog posts will live. These files are generally
[Markdown](https://daringfireball.net/projects/markdown/) or HTML, but can
be other formats with the proper converter installed.
All posts must have [YAML Front Matter](../frontmatter/), and they will be
converted from their source format into an HTML page that is part of your
static site.
### Creating Post Files
To create a new post, all you need to do is create a file in the `_posts`
directory. How you name files in this folder is important. Jekyll requires blog
post files to be named according to the following format:
```sh
YEAR-MONTH-DAY-title.MARKUP
```
Where `YEAR` is a four-digit number, `MONTH` and `DAY` are both two-digit
numbers, and `MARKUP` is the file extension representing the format used in the
file. For example, the following are examples of valid post filenames:
```sh
2011-12-31-new-years-eve-is-awesome.md
2012-09-12-how-to-write-a-blog.md
```
<div class="note">
<h5>ProTip™: Link to other posts</h5>
<p>
Use the <a href="../templates/#linking-to-posts"><code>post_url</code></a>
tag to link to other posts without having to worry about the URLs
breaking when the site permalink style changes.
</p>
</div>
### Content Formats
All blog post files must begin with [YAML Front Matter](../frontmatter/). After
that, it's simply a matter of deciding which format you prefer. Jekyll supports
[Markdown](https://daringfireball.net/projects/markdown/) out of the box,
and has [myriad extensions for other formats as well](/docs/plugins/#converters-1),
including the popular [Textile](http://redcloth.org/textile) format. These
formats each have their own way of marking up different types of content
within a post, so you should familiarize yourself with these formats and
decide which one best suits your needs.
<div class="note info">
<h5>Be aware of character sets</h5>
<p>
Content processors can modify certain characters to make them look nicer.
For example, the <code>smart</code> extension in Redcarpet converts standard,
ASCII quotation characters to curly, Unicode ones. In order for the browser
to display those characters properly, define the charset meta value by
including <code>&lt;meta charset=&quot;utf-8&quot;&gt;</code> in the
<code>&lt;head&gt;</code> of your layout.
</p>
</div>
## Including images and resources
Chances are, at some point, you'll want to include images, downloads, or other
digital assets along with your text content. While the syntax for linking to
these resources differs between Markdown and Textile, the problem of working
out where to store these files in your site is something everyone will face.
There are a number of ways to include digital assets in Jekyll.
One common solution is to create a folder in the root of the project directory
called something like `assets` or `downloads`, into which any images, downloads
or other resources are placed. Then, from within any post, they can be linked
to using the sites root as the path for the asset to include. Again, this will
depend on the way your sites (sub)domain and path are configured, but here are
some examples (in Markdown) of how you could do this using the `site.url`
variable in a post.
Including an image asset in a post:
```text
... which is shown in the screenshot below:
![My helpful screenshot]({% raw %}{{ site.url }}{% endraw %}/assets/screenshot.jpg)
```
Linking to a PDF for readers to download:
```text
... you can [get the PDF]({% raw %}{{ site.url }}{% endraw %}/assets/mydoc.pdf) directly.
```
<div class="note">
<h5>ProTip™: Link using just the site root URL</h5>
<p>
You can skip the <code>{% raw %}{{ site.url }}{% endraw %}</code> variable
if you <strong>know</strong> your site will only ever be displayed at the
root URL of your domain. In this case you can reference assets directly with
just <code>/path/file.jpg</code>.
</p>
</div>
## A typical post
Jekyll can handle many different iterations of the idea you might associate with a "post," however a standard blog style post, including a Title, Layout, Publishing Date, and Categories might look like this:
```
---
layout: post
title: "Welcome to Jekyll!"
date: 2015-11-17 16:16:01 -0600
categories: jekyll update
---
Youll find this post in your `_posts` directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run `bundle exec jekyll serve`, which launches a web server and auto-regenerates your site when a file is updated.
To add new posts, simply add a file in the `_posts` directory that follows the convention `YYYY-MM-DD-name-of-post.ext` and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.
```
Everything in between the first and second `---` are part of the YAML Front Matter, and everything after the second `---` will be rendered with Markdown and show up as "Content."
## Displaying an index of posts
Its all well and good to have posts in a folder, but a blog is no use unless
you have a list of posts somewhere. Creating an index of posts on another page
(or in a [template](../templates/)) is easy, thanks to the [Liquid template
language](https://docs.shopify.com/themes/liquid/basics) and its tags. Heres a
basic example of how to create a list of links to your blog posts:
```html
<ul>
{% raw %}{% for post in site.posts %}{% endraw %}
<li>
<a href="{% raw %}{{ post.url }}{% endraw %}">{% raw %}{{ post.title }}{% endraw %}</a>
</li>
{% raw %}{% endfor %}{% endraw %}
</ul>
```
Of course, you have full control over how (and where) you display your posts,
and how you structure your site. You should read more about [how templates
work](../templates/) with Jekyll if you want to know more.
Note that the `post` variable only exists inside the `for` loop above. If
you wish to access the currently-rendering page/posts's variables (the
variables of the post/page that has the `for` loop in it), use the `page`
variable instead.
## Post excerpts
Each post automatically takes the first block of text, from the beginning of
the content to the first occurrence of `excerpt_separator`, and sets it as the `post.excerpt`.
Take the above example of an index of posts. Perhaps you want to include
a little hint about the post's content by adding the first paragraph of each of
your posts:
```html
<ul>
{% raw %}{% for post in site.posts %}{% endraw %}
<li>
<a href="{% raw %}{{ post.url }}{% endraw %}">{% raw %}{{ post.title }}{% endraw %}</a>
{% raw %}{{ post.excerpt }}{% endraw %}
</li>
{% raw %}{% endfor %}{% endraw %}
</ul>
```
Because Jekyll grabs the first paragraph you will not need to wrap the excerpt
in `p` tags, which is already done for you. These tags can be removed with the
following if you'd prefer:
```html
{% raw %}{{ post.excerpt | remove: '<p>' | remove: '</p>' }}{% endraw %}
```
If you don't like the automatically-generated post excerpt, it can be
explicitly overridden by adding an `excerpt` value to your post's YAML
Front Matter. Alternatively, you can choose to define a custom
`excerpt_separator` in the post's YAML front matter:
```text
---
excerpt_separator: <!--more-->
---
Excerpt
<!--more-->
Out-of-excerpt
```
You can also set the `excerpt_separator` globally in your `_config.yml`
configuration file.
Completely disable excerpts by setting your `excerpt_separator` to `""`.
Also, as with any output generated by Liquid tags, you can pass the
`| strip_html` filter to remove any html tags in the output. This is
particularly helpful if you wish to output a post excerpt as a
`meta="description"` tag within the post `head`, or anywhere else having
html tags along with the content is not desirable.
## Highlighting code snippets
Jekyll also has built-in support for syntax highlighting of code snippets using
either Pygments or Rouge, and including a code snippet in any post is easy.
Just use the dedicated Liquid tag as follows:
```text
{% raw %}{% highlight ruby %}{% endraw %}
def show
@widget = Widget(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @widget }
end
end
{% raw %}{% endhighlight %}{% endraw %}
```
And the output will look like this:
```ruby
def show
@widget = Widget(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @widget }
end
end
```
<div class="note">
<h5>ProTip™: Show line numbers</h5>
<p>
You can make code snippets include line-numbers by adding the word
<code>linenos</code> to the end of the opening highlight tag like this:
<code>{% raw %}{% highlight ruby linenos %}{% endraw %}</code>.
</p>
</div>
These basics should be enough to get you started writing your first posts. When
youre ready to dig into what else is possible, you might be interested in
doing things like [customizing post permalinks](../permalinks/) or
using [custom variables](../variables/) in your posts and elsewhere on your
site.

title: Quick-start guide
permalink: /docs/quickstart/
---
If you already have a full [Ruby](https://www.ruby-lang.org/en/downloads/) development environment with all headers and [RubyGems](https://rubygems.org/pages/download) installed (see Jekyll's [requirements](/docs/installation/#requirements)), you can create a new Jekyll site by doing the following:
```sh
# Install Jekyll and Bundler gems through RubyGems
~ $ gem install jekyll bundler
# Create a new Jekyll site at ./myblog
~ $ jekyll new myblog
# Change into your new directory
~ $ cd myblog
# Build the site on the preview server
~/myblog $ bundle exec jekyll serve
# Now browse to http://localhost:4000
```
If you encounter any unexpected errors during the above, please refer to the [troubleshooting](/docs/troubleshooting/#configuration-problems) page or the already-mentioned [requirements](/docs/installation/#requirements) page, as you might be missing development headers or other prerequisites.
## About Bundler
`gem install jekyll bundler` installs the [jekyll](https://rubygems.org/gems/jekyll/) and [bundler](https://rubygems.org/gems/bundler) gems through [RubyGems](https://rubygems.org/). You need only to install the gems one time &mdash; not every time you create a new Jekyll project. Here are some additional details:
* `bundler` is a gem that manages other Ruby gems. It makes sure your gems and gem versions are compatible, and that you have all necessary dependencies each gem requires.
* The `Gemfile` and `Gemfile.lock` files inform Bundler about the gem requirements in your site. If your site doesn't have these Gemfiles, you can omit `bundle exec` and just run `jekyll serve`.
* When you run `bundle exec jekyll serve`, Bundler uses the gems and versions as specified in `Gemfile.lock` to ensure your Jekyll site builds with no compatibility or dependency conflicts.
## Options for creating a new site with Jekyll
`jekyll new <PATH>` installs a new Jekyll site at the path specified (relative to current directory). In this case, Jekyll will be installed in a directory called `myblog`. Here are some additional details:
* To install the Jekyll site into the directory you're currently in, run `jekyll new .` If the existing directory isn't empty, you can pass the `--force` option with `jekyll new . --force`.
* `jekyll new` automatically initiates `bundle install` to install the dependencies required. (If you don't want Bundler to install the gems, use `jekyll new myblog --skip-bundle`.)
* By default, the Jekyll site installed by `jekyll new` uses a gem-based theme called [Minima](https://github.com/jekyll/minima). With [gem-based themes](../themes), some of the directories and files are stored in the theme-gem, hidden from your immediate view.
* We recommend setting up Jekyll with a gem-based theme but if you want to start with a blank slate, use `jekyll new myblog --blank`
* To learn about other parameters you can include with `jekyll new`, type `jekyll new --help`.
When in doubt, use the <code>help</code> command to remind you of all available options and usage, it also works with the <code>new</code>, <code>build</code> and <code>serve</code> subcommands, e.g. <code>jekyll help new</code> or <code>jekyll help build</code>.
{: .note .info }
## Next steps
Building a Jekyll site with the default theme is just the first step. The real magic happens when you start creating blog posts, using the front matter to control templates and layouts, and taking advantage of all the awesome configuration options Jekyll makes available.

title: Static Files
permalink: /docs/static-files/
---
In addition to renderable and convertible content, we also have **static
files**.
A static file is a file that does not contain any YAML front matter. These
include images, PDFs, and other un-rendered content.
They're accessible in Liquid via `site.static_files` and contain the
following metadata:
<div class="mobile-side-scroller">
<table>
<thead>
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><p><code>file.path</code></p></td>
<td><p>
The relative path to the file, e.g. <code>/assets/img/image.jpg</code>
</p></td>
</tr>
<tr>
<td><p><code>file.modified_time</code></p></td>
<td><p>
The `Time` the file was last modified, e.g. <code>2016-04-01 16:35:26 +0200</code>
</p></td>
</tr>
<tr>
<td><p><code>file.name</code></p></td>
<td><p>
The string name of the file e.g. <code>image.jpg</code> for <code>image.jpg</code>
</p></td>
</tr>
<tr>
<td><p><code>file.basename</code></p></td>
<td><p>
The string basename of the file e.g. <code>image</code> for <code>image.jpg</code>
</p></td>
</tr>
<tr>
<td><p><code>file.extname</code></p></td>
<td><p>
The extension name for the file, e.g.
<code>.jpg</code> for <code>image.jpg</code>
</p></td>
</tr>
</tbody>
</table>
</div>
Note that in the above table, `file` can be anything. It's simply an arbitrarily set variable used in your own logic (such as in a for loop). It isn't a global site or page variable.
## Add front matter to static files
Although you can't directly add front matter values to static files, you can set front matter values through the [defaults property](../configuration/#front-matter-defaults) in your configuration file. When Jekyll builds the site, it will use the front matter values you set.
Here's an example:
In your `_config.yml` file, add the following values to the `defaults` property:
```yaml
defaults:
- scope:
path: "assets/img"
values:
image: true
```
This assumes that your Jekyll site has a folder path of `assets/img` where you have images (static files) stored. When Jekyll builds the site, it will treat each image as if it had the front matter value of `image: true`.
Suppose you want to list all your image assets as contained in `assets/img`. You could use this for loop to look in the `static_files` object and get all static files that have this front matter property:
```liquid
{% raw %}{% assign image_files = site.static_files | where: "image", true %}
{% for myimage in image_files %}
{{ myimage.path }}
{% endfor %}{% endraw %}
```
When you build your site, the output will list the path to each file that meets this front matter condition.

Jekyll is, at its core, a text transformation engine. The concept behind the
system is this: you give it text written in your favorite markup language, be
that Markdown, Textile, or just plain HTML, and it churns that through a layout
or a series of layout files. Throughout that process you can tweak how you want
the site URLs to look, what data gets displayed in the layout, and more. This
is all done through editing text files; the static web site is the final
product.
A basic Jekyll site usually looks something like this:
```sh
.

<h5>Directory structure of Jekyll sites using gem-based themes</h5>
<p>
Starting <strong>Jekyll 3.2</strong>, a new Jekyll project bootstrapped with <code>jekyll new</code> uses <a href="../themes/">gem-based themes</a> to define the look of the site. This results in a lighter default directory structure : <code>_layouts</code>, <code>_includes</code> and <code>_sass</code> are stored in the theme-gem, by default.
</p>
<br />
<p>
<a href="https://github.com/jekyll/minima">minima</a> is the current default theme, and <code>bundle show minima</code> will show you where minima theme's files are stored on your computer.

Jekyll uses the [Liquid](https://shopify.github.io/liquid/) templating language to
process templates. All of the standard Liquid [tags](https://shopify.github.io/liquid/tags/control-flow/) and
[filters](https://shopify.github.io/liquid/filters/abs/) are
supported. Jekyll even adds a few handy filters and tags of its own to make
common tasks easier.

### Options for the `slugify` filter
The `slugify` filter accepts an option, each specifying what to filter.
The default is `default`. They are as follows (with what they filter):
- `none`: no characters
- `raw`: spaces
- `default`: spaces and non-alphanumeric characters
- `pretty`: spaces and non-alphanumeric characters except for `._~!$&'()+,;=@`
## Tags
### Includes
If you have small page snippets that you want to include in multiple places on your site, save the snippets as *include files* and insert them where required, by using the `include` tag:
```liquid
{% raw %}{% include footer.html %}{% endraw %}
```
Jekyll expects all *include files* to be placed in an `_includes` directory at the root of your source directory. In the above example, this will embed the contents of `_includes/footer.html` into the calling file.
For more advanced information on using includes, see [Includes](../includes).
### Code snippet highlighting
Jekyll has built in support for syntax highlighting of over 60 languages
thanks to [Rouge](http://rouge.jneen.net). Rouge is the default highlighter
in Jekyll 3 and above. To use it in Jekyll 2, set `highlighter` to `rouge`
and ensure the `rouge` gem is installed properly.
Alternatively, you can use [Pygments](http://pygments.org) to highlight
your code snippets. To use Pygments, you must have Python installed on your
system, have the `pygments.rb` gem installed and set `highlighter` to
`pygments` in your site's configuration file. Pygments supports [over 100
languages](http://pygments.org/languages/)
To render a code block with syntax highlighting, surround your code as follows:
```liquid
{% raw %}
{% highlight ruby %}
def foo
puts 'foo'
end
{% endhighlight %}
{% endraw %}
```
The argument to the `highlight` tag (`ruby` in the example above) is the
language identifier. To find the appropriate identifier to use for the language
you want to highlight, look for the “short name” on the [Rouge
wiki](https://github.com/jayferd/rouge/wiki/List-of-supported-languages-and-lexers)
or the [Pygments' Lexers page](http://pygments.org/docs/lexers/).
#### Line numbers
There is a second argument to `highlight` called `linenos` that is optional.
Including the `linenos` argument will force the highlighted code to include line
numbers. For instance, the following code block would include line numbers next
to each line:
```liquid
{% raw %}
{% highlight ruby linenos %}
def foo
puts 'foo'
end
{% endhighlight %}
{% endraw %}
```
#### Stylesheets for syntax highlighting
In order for the highlighting to show up, youll need to include a highlighting
stylesheet. For an example stylesheet you can look at
[syntax.css](https://github.com/mojombo/tpw/tree/master/css/syntax.css). These
are the same styles as used by GitHub and you are free to use them for your own
site. If you use `linenos`, you might want to include an additional CSS class
definition for the `.lineno` class in `syntax.css` to distinguish the line
numbers from the highlighted code.
### Gist
Use the `gist` tag to easily embed a GitHub Gist onto your site. This works
with public or secret gists:
```liquid
{% raw %}
{% gist parkr/931c1c8d465a04042403 %}
{% endraw %}
```
You may also optionally specify the filename in the gist to display:
```liquid
{% raw %}
{% gist parkr/931c1c8d465a04042403 jekyll-private-gist.markdown %}
{% endraw %}
```
To use the `gist` tag, you'll need to add the
[jekyll-gist](https://github.com/jekyll/jekyll-gist) gem to your project.
## Links
### Linking to pages {#link}
To link to a post, a page, collection item, or file, the `link` tag will generate the correct permalink URL for the path you specify. For example, if you use the `link` tag to link to `mypage.html`, even if you change your permalink style to include the file extension or omit it, the URL formed by the `link` tag will always be valid.
You must include the file's original extension when using the `link` tag. Here are some examples:
```liquid
{% raw %}
{{ site.baseurl }}{% link _collection/name-of-document.md %}
{{ site.baseurl }}{% link _posts/2016-07-26-name-of-post.md %}
{{ site.baseurl }}{% link news/index.html %}
{{ site.baseurl }}{% link /assets/files/doc.pdf %}
{% endraw %}
```
You can also use the `link` tag to create a link in Markdown as follows:
```liquid
{% raw %}
[Link to a document]({{ site.baseurl }}{% link _collection/name-of-document.md %})
[Link to a post]({{ site.baseurl }}{% link _posts/2016-07-26-name-of-post.md %})
[Link to a page]({{ site.baseurl }}{% link news/index.html %})
[Link to a file]({{ site.baseurl }}{% link /assets/files/doc.pdf %})
{% endraw %}
```
(Including `{% raw %}{{ site.baseurl }}{% endraw %}` is optional &mdash; it depends on whether you want to preface the page URL with the `baseurl` value.)
The path to the post, page, or collection is defined as the path relative to the root directory (where your config file is) to the file, not the path from your existing page to the other page.
For example, suppose you're creating a link in `page_a.md` (stored in `pages/folder1/folder2`) to `page_b.md` (stored in `pages/folder1`). Your path in the link would not be `../page_b.html`. Instead, it would be `/pages/folder1/page_b.md`.
If you're unsure of the path, add `{% raw %}{{ page.path }}{% endraw %}` to the page and it will display the path.
One major benefit of using the `link` tag is link validation. If the link doesn't exist, Jekyll won't build your site. This is a good thing, as it will alert you to a broken link so you can fix it (rather than allowing you to build and deploy a site with broken links).
Note you cannot add filters to `link` tags. For example, you cannot append a string using Liquid filters, such as `{% raw %}{% link mypage.html | append: "#section1" %} {% endraw %}`. To link to sections on a page, you will need to use regular HTML or Markdown linking techniques.
### Linking to posts
If you want to include a link to a post on your site, the `post_url` tag will generate the correct permalink URL for the post you specify.
```liquid
{% raw %}
{{ site.baseurl }}{% post_url 2010-07-21-name-of-post %}
{% endraw %}
```
If you organize your posts in subdirectories, you need to include subdirectory path to the post:
```liquid
{% raw %}
{{ site.baseurl }}{% post_url /subdir/2010-07-21-name-of-post %}
{% endraw %}
```
There is no need to include the file extension when using the `post_url` tag.
You can also use this tag to create a link to a post in Markdown as follows:
```liquid
{% raw %}
[Name of Link]({{ site.baseurl }}{% post_url 2010-07-21-name-of-post %})
{% endraw %}
```

title: Themes
permalink: /docs/themes/
---
Jekyll has an extensive theme system that allows you to leverage community-maintained templates and styles to customize your site's presentation. Jekyll themes package up layouts, includes, and stylesheets in a way that can be overridden by your site's content.
## Understanding gem-based themes
When you [create a new Jekyll site](/docs/quickstart) (by running the `jekyll new <PATH>` command), Jekyll installs a site that uses a gem-based theme called [Minima](https://github.com/jekyll/minima).
With gem-based themes, some of the site's directories (such as the `assets`, `_layouts`, `_includes`, and `_sass` directories) are stored in the theme's gem, hidden from your immediate view. Yet all of the necessary directories will be read and processed during Jekyll's build process.
In the case of Minima, you see only the following files in your Jekyll site directory:
```
├── Gemfile
├── Gemfile.lock
├── _config.yml
├── _posts
│ └── 2016-12-04-welcome-to-jekyll.markdown
├── about.md
└── index.md
```
The `Gemfile` and `Gemfile.lock` files are used by Bundler to keep track of the required gems and gem versions you need to build your Jekyll site.
Gem-based themes make it easy for theme developers to make updates available to anyone who has the theme gem. When there's an update, theme developers push the update to RubyGems.
If you have the theme gem, you can (if you desire) run `bundle update` to update all gems in your project. Or you can run `bundle update <THEME>`, replacing `<THEME>` with the theme name, such as `minima`, to just update the theme gem. Any new files or updates the theme developer has made (such as to stylesheets or includes) will be pulled into your project automatically.
The goal of gem-based themes is to allow you to get all the benefits of a robust, continually updated theme without having all the theme's files getting in your way and over-complicating what might be your primary focus: creating content.
## Overriding theme defaults
Jekyll themes set default layouts, includes, and stylesheets. However, you can override any of the theme defaults with your own site content.
To replace layouts or includes in your theme, make a copy in your `_layouts` or `_includes` directory of the specific file you wish to modify, or create the file from scratch giving it the same name as the file you wish to override.
For example, if your selected theme has a `page` layout, you can override the theme's layout by creating your own `page` layout in the `_layouts` directory (that is, `_layouts/page.html`).
To locate a theme's files on your computer:
1. Run `bundle show` followed by the name of the theme's gem, e.g., `bundle show minima` for Jekyll's default theme.
This returns the location of the gem-based theme files. For example, the Minima theme's files might be located in `/usr/local/lib/ruby/gems/2.3.0/gems/minima-2.1.0` on macOS.
2. Open the theme's directory in Finder or Explorer:
```shell
# On MacOS
open $(bundle show minima)
# On Windows
explorer /usr/local/lib/ruby/gems/2.3.0/gems/minima-2.1.0
```
A Finder or Explorer window opens showing the theme's files and directories. The Minima theme gem contains these files:
```
├── LICENSE.txt
├── README.md
├── _includes
│   ├── disqus_comments.html
│   ├── footer.html
│   ├── google-analytics.html
│   ├── head.html
│   ├── header.html
│   ├── icon-github.html
│   ├── icon-github.svg
│   ├── icon-twitter.html
│   └── icon-twitter.svg
├── _layouts
│   ├── default.html
│   ├── home.html
│   ├── page.html
│   └── post.html
├── _sass
│   ├── minima
│   │   ├── _base.scss
│   │   ├── _layout.scss
│   │   └── _syntax-highlighting.scss
│   └── minima.scss
└── assets
└── main.scss
```
With a clear understanding of the theme's files, you can now override any theme file by creating a similarly named file in your Jekyll site directory.
Let's say, for a second example, you want to override Minima's footer. In your Jekyll site, create an `_includes` folder and add a file in it called `footer.html`. Jekyll will now use your site's `footer.html` file instead of the `footer.html` file from the Minima theme gem.
To modify any stylesheet you must take the extra step of also copying the main sass file (`_sass/minima.scss` in the Minima theme) into the `_sass` directory in your site's source.
Jekyll will look first to your site's content before looking to the theme's defaults for any requested file in the following folders:
- `/assets`
- `/_layouts`
- `/_includes`
- `/_sass`
Note that making copies of theme files will prevent you from receiving any theme updates on those files. An alternative, to continue getting theme updates on all stylesheets, is to use higher specificity CSS selectors in your own additional, originally named CSS files.
Refer to your selected theme's documentation and source repository for more information on what files you can override.
{: .note .info}
## Converting gem-based themes to regular themes
Suppose you want to get rid of the gem-based theme and convert it to a regular theme, where all files are present in your Jekyll site directory, with nothing stored in the theme gem.
To do this, copy the files from the theme gem's directory into your Jekyll site directory. (For example, copy them to `/myblog` if you created your Jekyll site at `/myblog`. See the previous section for details.)
Then remove references to the theme gem in `Gemfile` and configuration. For example, to remove `minima`:
- Open `Gemfile` and remove `gem "minima", "~> 2.0"`.
- Open `_config.yml` and remove `theme: minima`.
Now `bundle update` will no longer get updates for the theme gem.
## Installing a gem-based theme {#installing-a-theme}
The `jekyll new <PATH>` command isn't the only way to create a new Jekyll site with a gem-based theme. You can also find gem-based themes online and incorporate them into your Jekyll project.
For example, search for [jekyll theme on RubyGems](https://rubygems.org/search?utf8=%E2%9C%93&query=jekyll-theme) to find other gem-based themes. (Note that not all themes are using `jekyll-theme` as a convention in the theme name.)
To install a gem-based theme:
1. Add the theme to your site's `Gemfile`:
```sh
gem "jekyll-theme-awesome"
```
2. Install the theme:
```sh
bundle install
```
3. Add the following to your site's `_config.yml` to activate the theme:
```sh
theme: jekyll-theme-awesome
```
4. Build your site:
```sh
bundle exec jekyll serve
```
You can have multiple themes listed in your site's `Gemfile`, but only one theme can be selected in your site's `_config.yml`.
{: .note .info }
If you're publishing your Jekyll site on [GitHub Pages](https://pages.github.com/), note that GitHub Pages supports only some gem-based themes. See [Supported Themes](https://pages.github.com/themes/) in GitHub's documentation to see which themes are supported.
## Creating a gem-based theme
If you're a Jekyll theme developer (rather than just a consumer of themes), you can package up your theme in RubyGems and allow users to install it through Bundler.
If you're unfamiliar with creating Ruby gems, don't worry. Jekyll will help you scaffold a new theme with the `new-theme` command. Run `jekyll new-theme` with the theme name as an argument.
Here is an example:
```sh
jekyll new-theme jekyll-theme-awesome
create /path/to/jekyll-theme-awesome/_layouts
create /path/to/jekyll-theme-awesome/_includes
create /path/to/jekyll-theme-awesome/_sass
create /path/to/jekyll-theme-awesome/_layouts/page.html
create /path/to/jekyll-theme-awesome/_layouts/post.html
create /path/to/jekyll-theme-awesome/_layouts/default.html
create /path/to/jekyll-theme-awesome/Gemfile
create /path/to/jekyll-theme-awesome/jekyll-theme-awesome.gemspec
create /path/to/jekyll-theme-awesome/README.md
create /path/to/jekyll-theme-awesome/LICENSE.txt
initialize /path/to/jekyll-theme-awesome/.git
create /path/to/jekyll-theme-awesome/.gitignore
Your new Jekyll theme, jekyll-theme-awesome, is ready for you in /path/to/jekyll-theme-awesome!
For help getting started, read /path/to/jekyll-theme-awesome/README.md.
```
Add your template files in the corresponding folders. Then complete the `.gemspec` and the README files according to your needs.
### Layouts and includes
Theme layouts and includes work just like they work in any Jekyll site. Place layouts in your theme's `/_layouts` folder, and place includes in your themes `/_includes` folder.
For example, if your theme has a `/_layouts/page.html` file, and a page has `layout: page` in its YAML front matter, Jekyll will first look to the site's `_layouts` folder for the `page` layout, and if none exists, will use your theme's `page` layout.
### Assets
Any file in `/assets` will be copied over to the user's site upon build unless they have a file with the same relative path. You can ship any kind of asset here: SCSS, an image, a webfont, etc. These files behave like pages and static files in Jekyll:
- If the file has [YAML front matter](/docs/frontmatter/) at the top, it will be rendered.
- If the file does not have YAML front matter, it will simply be copied over into the resulting site.
This allows theme creators to ship a default `/assets/styles.scss` file which their layouts can depend on as `/assets/styles.css`.
All files in `/assets` will be output into the compiled site in the `/assets` folder just as you'd expect from using Jekyll on your sites.
### Stylesheets
Your theme's stylesheets should be placed in your theme's `_sass` folder, again, just as you would when authoring a Jekyll site.
```
_sass
├── jekyll-theme-awesome.scss
```
Your theme's styles can be included in the user's stylesheet using the `@import` directive.
```css
{% raw %}@import "{{ site.theme }}";{% endraw %}
```
### Theme-gem dependencies
From `v3.5`, Jekyll will automatically require all whitelisted `runtime_dependencies` of your theme-gem even if they're not explicitly included under the `gems` array in the site's config file. (NOTE: whitelisting is only required when building or serving with the `--safe` option.)
With this, the end-user need not keep track of the plugins required to be included in their config file for their theme-gem to work as intended.
### Documenting your theme
Your theme should include a `/README.md` file, which explains how site authors can install and use your theme. What layouts are included? What includes? Do they need to add anything special to their site's configuration file?
### Adding a screenshot
Themes are visual. Show users what your theme looks like by including a screenshot as `/screenshot.png` within your theme's repository where it can be retrieved programatically. You can also include this screenshot within your theme's documentation.
### Previewing your theme
To preview your theme as you're authoring it, it may be helpful to add dummy content in, for example, `/index.html` and `/page.html` files. This will allow you to use the `jekyll build` and `jekyll serve` commands to preview your theme, just as you'd preview a Jekyll site.
If you do preview your theme locally, be sure to add `/_site` to your theme's `.gitignore` file to prevent the compiled site from also being included when you distribute your theme.
{: .info .note}
### Publishing your theme
Themes are published via [RubyGems.org](https://rubygems.org). You will need a RubyGems account, which you can [create for free](https://rubygems.org/sign_up).
1. First, you need to have it in a git repository:
```sh
git init # Only the first time
git add -A
git commit -m "Init commit"
```
2. Next, package your theme, by running the following command, replacing `jekyll-theme-awesome` with the name of your theme:
```sh
gem build jekyll-theme-awesome.gemspec
```
3. Finally, push your packaged theme up to the RubyGems service, by running the following command, again replacing `jekyll-theme-awesome` with the name of your theme:
```sh
gem push jekyll-theme-awesome-*.gem
```
4. To release a new version of your theme, update the version number in the gemspec file, ( `jekyll-theme-awesome.gemspec` in this example ), and then repeat Steps 1 - 3 above. We recommend that you follow [Semantic Versioning](http://semver.org/) while bumping your theme-version.

title: Troubleshooting
permalink: /docs/troubleshooting/

If you ever run into problems installing or using Jekyll, here are a few tips
that might be of help. If the problem youre experiencing isnt covered below,
**please [check out our other help resources](/help/)** as well.
- [Installation Problems](#installation-problems)
- [Problems running Jekyll](#problems-running-jekyll)
- [Base-URL Problems](#base-url-problems)
- [Configuration problems](#configuration-problems)
- [Markup Problems](#markup-problems)
- [Production Problems](#production-problems)
## Installation Problems
If you encounter errors during gem installation, you may need to install
the header files for compiling extension modules for Ruby 2.x This
can be done on Ubuntu or Debian by running:
```sh
sudo apt-get install ruby2.3-dev
```
On Red Hat, CentOS, and Fedora systems you can do this by running:
```sh
sudo yum install ruby-devel
```
If you installed the above - specifically on Fedora 23 - but the extensions would still not compile, you are probably running a Fedora image that misses the `redhat-rpm-config` package. To solve this, simply run:
```sh
sudo dnf install redhat-rpm-config
```
On Ubuntu if you get stuck after `bundle exec jekyll serve` and see error
messages like `Could not locate Gemfile` or `.bundle/ directory`, it's likely
because all requirements have not been fully met. Recent stock Ubuntu
distributions require the installation of both the `ruby` and `ruby-all-dev`
packages:
```sh
sudo apt-get install ruby ruby-all-dev
```
On [NearlyFreeSpeech](https://www.nearlyfreespeech.net/) you need to run the
following commands before installing Jekyll:
```sh
export GEM_HOME=/home/private/gems
export GEM_PATH=/home/private/gems:/usr/local/lib/ruby/gems/1.8/
export PATH=$PATH:/home/private/gems/bin
export RB_USER_INSTALL='true'
```
To install RubyGems on Gentoo:
```sh
sudo emerge -av dev-ruby/rubygems
```
On Windows, you may need to install [RubyInstaller
DevKit](https://wiki.github.com/oneclick/rubyinstaller/development-kit).
On Android (with Termux) you can install all requirements by running:
```sh
apt update && apt install libffi-dev clang ruby-dev make
```
On macOS, you may need to update RubyGems (using `sudo` only if necessary):
```sh
sudo gem update --system
```
If you still have issues, you can download and install new Command Line
Tools (such as `gcc`) using the following command:
```sh
xcode-select --install
```
which may allow you to install native gems using this command (again using
`sudo` only if necessary):
```sh
sudo gem install jekyll
```
Note that upgrading macOS does not automatically upgrade Xcode itself
(that can be done separately via the App Store), and having an out-of-date
Xcode.app can interfere with the command line tools downloaded above. If
you run into this issue, upgrade Xcode and install the upgraded Command
Line Tools.
### Jekyll &amp; Mac OS X 10.11
With the introduction of System Integrity Protection, several directories
that were previously writable are now considered system locations and are no
longer available. Given these changes, there are a couple of simple ways to get
up and running. One option is to change the location where the gem will be
installed (again using `sudo` only if necessary):
```sh
sudo gem install -n /usr/local/bin jekyll
```
Alternatively, Homebrew can be installed and used to set up Ruby. This can be
done as follows:
```sh
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
```
Once Homebrew is installed, the second step is easy:
```sh
brew install ruby
```
Advanced users (with more complex needs) may find it helpful to choose one of a
number of Ruby version managers ([RVM][], [rbenv][], [chruby][], [etc][].) in
which to install Jekyll.
[RVM]: https://rvm.io
[rbenv]: http://rbenv.org
[chruby]: https://github.com/postmodern/chruby
[etc]: https://github.com/rvm/rvm/blob/master/docs/alt.md
If you elect to use one of the above methods to install Ruby, it might be
necessary to modify your `$PATH` variable using the following command:
```sh
export PATH=/usr/local/bin:$PATH
```
GUI apps can modify the `$PATH` as follows:
```sh
launchctl setenv PATH "/usr/local/bin:$PATH"
```
Either of these approaches are useful because `/usr/local` is considered a
"safe" location on systems which have SIP enabled, they avoid potential
conflicts with the version of Ruby included by Apple, and it keeps Jekyll and
its dependencies in a sandboxed environment. This also has the added
benefit of not requiring `sudo` when you want to add or remove a gem.
### Could not find a JavaScript runtime. (ExecJS::RuntimeUnavailable)
This error can occur during the installation of `jekyll-coffeescript` when
you don't have a proper JavaScript runtime. To solve this, either install
`execjs` and `therubyracer` gems, or install `nodejs`. Check out
[issue #2327](https://github.com/jekyll/jekyll/issues/2327) for more info.
## Problems running Jekyll
On Debian or Ubuntu, you may need to add `/var/lib/gems/1.8/bin/` to your path
in order to have the `jekyll` executable be available in your Terminal.
## Base-URL Problems
If you are using base-url option like:
```sh
jekyll serve --baseurl '/blog'
```
… then make sure that you access the site at:
```sh
http://localhost:4000/blog/index.html
```
It wont work to just access:
```sh
http://localhost:4000/blog
```
## Configuration problems
The order of precedence for conflicting [configuration settings](../configuration/)
is as follows:
1. Command-line flags
2. Configuration file settings
3. Defaults
That is: defaults are overridden by options specified in `_config.yml`,
and flags specified at the command-line will override all other settings
specified elsewhere.
If you encounter an error in building the site, with the error message
"'0000-00-00-welcome-to-jekyll.markdown.erb' does not have a valid date in the
YAML front matter." try including the line `exclude: [vendor]`
in `_config.yml`.
## Markup Problems
The various markup engines that Jekyll uses may have some issues. This
page will document them to help others who may run into the same
problems.
### Liquid
The latest version, version 2.0, seems to break the use of `{{ "{{" }}` in
templates. Unlike previous versions, using `{{ "{{" }}` in 2.0 triggers the
following error:
```sh
'{{ "{{" }}' was not properly terminated with regexp: /\}\}/ (Liquid::SyntaxError)
```
### Excerpts
Since v1.0.0, Jekyll has had automatically-generated post excerpts. Since
v1.1.0, Jekyll also passes these excerpts through Liquid, which can cause
strange errors where references don't exist or a tag hasn't been closed. If you
run into these errors, try setting `excerpt_separator: ""` in your
`_config.yml`, or set it to some nonsense string.
## Production Problems
If you run into an issue that a static file can't be found in your
production environment during build since v3.2.0 you should set your
[environment to `production`](../configuration/#specifying-a-jekyll-environment-at-build-time).
The issue is caused by trying to copy a non-existing symlink.

Upgrading from an older version of Jekyll? Upgrading to a new major version of Jekyll (e.g. from v2.x to v3.x) may cause some headaches. Take the following guides to aid your upgrade:
- [From 0.x to 1.x and 2.x](/docs/upgrading/0-to-2/)
- [From 2.x to 3.x](/docs/upgrading/2-to-3/)
If you are making a minor update (for example from 3.3.1 to the latest version at the time 3.3.2) run 'bundle update jekyll' when in your site directory.
If you would like to update all your gems, run 'bundle update' when in your site directory.

Upgrading from an older version of Jekyll? A few things have changed in 1.0
and 2.0 that you'll want to know about.
Before we dive in, go ahead and fetch the latest version of Jekyll:
```sh
$ gem update jekyll
```
<div class="note feature">
<h5 markdown="1">Diving in</h5>
<p markdown="1">Want to get a new Jekyll site up and running quickly? Simply
run <code>jekyll new SITENAME</code> to create a new folder with a bare bones
Jekyll site.</p>
</div>
### The Jekyll Command
For better clarity, Jekyll now accepts the commands `build` and `serve`.
Whereas before you might simply run the command `jekyll` to generate a site
and `jekyll --server` to view it locally, in v2.0 (and later) you should
use the subcommands `jekyll build` and `jekyll serve` to build and preview
your site.
<div class="note info">
<h5>Watching and Serving</h5>
<p markdown="1">With the new subcommands, the way sites are previewed locally
changed a bit. Instead of specifying `server: true` in the site's
configuration file, use `jekyll serve`. The same holds true for
`watch: true`. Instead, use the `--watch` flag with either `jekyll serve`
or `jekyll build`.</p>
</div>
### Absolute Permalinks
In Jekyll v1.0, we introduced absolute permalinks for pages in
subdirectories. Starting with v2.0, absolute permalinks are opt-out,
meaning Jekyll will default to using absolute permalinks instead of
relative permalinks. Relative permalink backwards-compatibility was removed in v3.0.
<div class="note warning" id="absolute-permalinks-warning">
<h5 markdown="1">Absolute permalinks will be required in v3.0 and on</h5>
<p markdown="1">
Starting with Jekyll v3.0, relative permalinks functionality will be removed and thus unavailable for use.
</p>
</div>
### Draft Posts
Jekyll now lets you write draft posts, and allows you to easily preview how
they will look prior to publishing. To start a draft, simply create a folder
called `_drafts` in your site's source directory (e.g., alongside `_posts`),
and add a new markdown file to it. To preview your new post, simply run the
`jekyll serve` command with the `--drafts` flag.
<div class="note info">
<h5 markdown="1">Drafts don't have dates</h5>
<p markdown="1">
Unlike posts, drafts don't have a date, since they haven't
been published yet. Rather than naming your draft something like
`2013-07-01-my-draft-post.md`, simply name the file what you'd like your
post to eventually be titled, here `my-draft-post.md`.</p>
</div>
### Custom Config File
Rather than passing individual flags via the command line, you can now pass
an entire custom Jekyll config file. This helps to distinguish between
environments, or lets you programmatically override user-specified
defaults. Simply add the `--config` flag to the `jekyll` command, followed
by the path to one or more config files (comma-delimited, no spaces).
#### As a result, the following command line flags are now deprecated:
* `--no-server`
* `--no-auto` (now `--no-watch`)
* `--auto` (now `--watch`)
* `--server`
* `--url=`
* `--maruku`, `--rdiscount`, and `--redcarpet`
* `--pygments`
* `--permalink=`
* `--paginate`
<div class="note info">
<h5>The config flag explicitly specifies your configuration file(s)</h5>
<p markdown="1">If you use the `--config` flag, Jekyll will ignore your
`_config.yml` file. Want to merge a custom configuration with the normal
configuration? No problem. Jekyll will accept more than one custom config
file via the command line. Config files cascade from right to left, such
that if I run `jekyll serve --config _config.yml,_config-dev.yml`,
the values in the config files on the right (`_config-dev.yml`) overwrite
those on the left (`_config.yml`) when both contain the same key.</p>
</div>
### New Config File Options
Jekyll 1.0 introduced several new config file options. Before you upgrade,
you should check to see if any of these are present in your pre-1.0 config
file, and if so, make sure that you're using them properly:
* `excerpt_separator`
* `host`
* `include`
* `keep_files`
* `layouts`
* `show_drafts`
* `timezone`
* `url`
### Baseurl
Often, you'll want the ability to run a Jekyll site in multiple places,
such as previewing locally before pushing to GitHub Pages. Jekyll 1.0 makes
that easier with the new `--baseurl` flag. To take advantage of this
feature, first add the production `baseurl` to your site's `_config.yml`
file. Then, throughout the site, simply prefix relative URLs
with `{% raw %}{{ site.baseurl }}{% endraw %}`.
When you're ready to preview your site locally, pass along the `--baseurl`
flag with your local baseurl (most likely `/`) to `jekyll serve` and Jekyll
will swap in whatever you've passed along, ensuring all your links work as
you'd expect in both environments.
<div class="note warning">
<h5 markdown="1">All page and post URLs contain leading slashes</h5>
<p markdown="1">If you use the method described above, please remember
that the URLs for all posts and pages contain a leading slash. Therefore,
concatenating the site baseurl and the post/page url where
`site.baseurl = /` and `post.url = /2013/06/05/my-fun-post/` will
result in two leading slashes, which will break links. It is thus
suggested that prefixing with `site.baseurl` only be used when the
`baseurl` is something other than the default of `/`.</p>

title: Upgrading from 2.x to 3.x
permalink: /docs/upgrading/2-to-3/

Upgrading from an older version of Jekyll? A few things have changed in 3.0
that you'll want to know about.
Before we dive in, go ahead and fetch the latest version of Jekyll:
```sh
$ gem update jekyll
```
Please note: Jekyll 3.2 requires Ruby version >= 2.1
<div class="note feature">
<h5 markdown="1">Diving in</h5>
<p markdown="1">Want to get a new Jekyll site up and running quickly? Simply
run <code>jekyll new SITENAME</code> to create a new folder with a bare bones
Jekyll site.</p>
</div>
### site.collections has changed
In 2.x, your iterations over `site.collections` yielded an array with the collection
label and the collection object as the first and second items, respectively. In 3.x,
this complication has been removed and iterations now yield simply the collection object.
A simple conversion must be made in your templates:
- `collection[0]` becomes `collection.label`
- `collection[1]` becomes `collection`
When iterating over `site.collections`, ensure the above conversions are made.
For `site.collections.myCollection` in Jekyll 2, you now do:
```liquid
{% raw %}
{% assign myCollection = site.collections | where: "label", "myCollection" | first %}
{% endraw %}
```
This is a bit cumbersome at first, but is easier than a big `for` loop.
### Dropped dependencies
We dropped a number of dependencies the Core Team felt were optional. As such, in 3.0, they must be explicitly installed and included if you use any of the features. They are:
- jekyll-paginate Jekyll's pagination solution from days past
- jekyll-coffeescript processing of CoffeeScript
- jekyll-gist the `gist` Liquid tag
- pygments.rb the Pygments highlighter
- redcarpet the Markdown processor
- toml an alternative to YAML for configuration files
- classifier-reborn for `site.related_posts`
### Future posts
A seeming feature regression in 2.x, the `--future` flag was automatically _enabled_.
The future flag allows post authors to give the post a date in the future and to have
it excluded from the build until the system time is equal or after the post time.
In Jekyll 3, this has been corrected. **Now, `--future` is disabled by default.**
This means you will need to include `--future` if you want your future-dated posts to
generate when running `jekyll build` or `jekyll serve`.
<div class="note info">
<h5>Future Posts on GitHub Pages</h5>
<p>
An exception to the above rule are GitHub Pages sites, where the <code>--future</code> flag remains <em>enabled</em>
by default to maintain historical consistency for those sites.
</p>
</div>
### Layout metadata
Introducing: `layout`. In Jekyll 2 and below, any metadata in the layout was merged onto
the `page` variable in Liquid. This caused a lot of confusion in the way the data was
merged and some unexpected behaviour. In Jekyll 3, all layout data is accessible via `layout`
in Liquid. For example, if your layout has `class: my-layout` in its YAML front matter,
then the layout can access that via `{% raw %}{{ layout.class }}{% endraw %}`.
### Syntax highlighter changed
For the first time, the default syntax highlighter has changed for the
`highlight` tag and for backtick code blocks. Instead of [Pygments.rb](https://github.com/tmm1/pygments.rb),
it's now [Rouge](http://rouge.jneen.net/). If you were using the `highlight` tag with certain
options, such as `hl_lines`, they may not be available when using Rouge. To
go back to using Pygments, set `highlighter: pygments` in your
`_config.yml` file and run `gem install pygments.rb` or add
`gem 'pygments.rb'` to your project's `Gemfile`.
### Relative Permalink support removed
In Jekyll 3 and above, relative permalinks have been deprecated. If you
created your site using Jekyll 2 and below, you may receive the following
error when trying to **serve** or **build**:
```text
Since v3.0, permalinks for pages in subfolders must be relative to the site
source directory, not the parent directory. Check
https://jekyllrb.com/docs/upgrading/ for more info.
```
This can be fixed by removing the following line from your `_config.yml` file:
```yaml
relative_permalinks: true
```
### Permalinks no longer automatically add a trailing slash
In Jekyll 2, any URL constructed from the `permalink:` field had a trailing slash (`/`) added to it automatically. Jekyll 3 no longer adds a trailing slash automatically to `permalink:` URLs. This can potentially result in old links to pages returning a 404 error. For example, suppose a page previously contained the YAML `permalink: /:year-:month-:day-:title` that resulted in the URL `example.com/2016-02-01-test/` (notice the trailing slash), Jekyll internally generates a folder named `2016-02-01-test`. In Jekyll 3, the same `permalink:` generate the file `2016-02-01-test.html` and the URL for the same page will be `example.com/2016-02-01-test`, and consequently any links to the old URL will result in a 404 error. In order to maintain the same URLs and avoid this problem, a trailing slash should be added to the `permalink:` field, for example `permalink: /:year-:month-:day-:title/`.
### All my posts are gone! Where'd they go!
Try adding `future: true` to your `_config.yml` file. Are they showing up now? If they are, then you were ensnared by an issue with the way Ruby parses times. Each of your posts is being read in a different timezone than you might expect and, when compared to the computer's current time, is "in the future." The fix for this is to add [a timezone offset](https://en.wikipedia.org/wiki/List_of_UTC_time_offsets) to each post (and make sure you remove `future: true` from your `_config.yml` file). If you're writing from California, for example, you would change this:
```yaml
---
date: 2016-02-06 19:32:10
---
```
to this (note the offset):
```yaml
---
date: 2016-02-06 19:32:10 -0800
---
```
### My categories have stopped working!
If you organized your categories as `/_posts/code/2008-12-24-closures.md`, you will need to restructure your directories to put the categories _above_ the `_posts` directories, as follows: `/code/_posts/2008-12-24-closures.md`.

title: Basic Usage
permalink: /docs/usage/
---
The Jekyll gem makes a `jekyll` executable available to you in your Terminal
window. You can use this command in a number of ways:
```sh
$ jekyll build
# => The current folder will be generated into ./_site
$ jekyll build --destination <destination>
# => The current folder will be generated into <destination>
$ jekyll build --source <source> --destination <destination>
# => The <source> folder will be generated into <destination>
$ jekyll build --watch
# => The current folder will be generated into ./_site,
# watched for changes, and regenerated automatically.
```
<div class="note info">
<h5>Changes to _config.yml are not included during automatic regeneration.</h5>
<p>
The <code>_config.yml</code> master configuration file contains global configurations
and variable definitions that are read once at execution time. Changes made to <code>_config.yml</code>
during automatic regeneration are not loaded until the next execution.
</p>
<p>
Note <a href="../datafiles">Data Files</a> are included and reloaded during automatic regeneration.
</p>
</div>
<div class="note warning">
<h5>Destination folders are cleaned on site builds</h5>
<p>
The contents of <code>&lt;destination&gt;</code> are automatically
cleaned, by default, when the site is built. Files or folders that are not
created by your site will be removed. Files and folders you wish to retain
in <code>&lt;destination&gt;</code> may be specified within the <code>&lt;keep_files&gt;</code>
configuration directive.
</p>
<p>
Do not use an important location for <code>&lt;destination&gt;</code>;
instead, use it as a staging area and copy files from there to your web server.
</p>
</div>
Jekyll also comes with a built-in development server that will allow you to
preview what the generated site will look like in your browser locally.
```sh
$ jekyll serve
# => A development server will run at http://localhost:4000/
# Auto-regeneration: enabled. Use `--no-watch` to disable.
$ jekyll serve --detach
# => Same as `jekyll serve` but will detach from the current terminal.
# If you need to kill the server, you can `kill -9 1234` where "1234" is the PID.
# If you cannot find the PID, then do, `ps aux | grep jekyll` and kill the instance.
```
<div class="note info">
<h5>Be aware of default behavior</h5>
<p>
As of version 2.4, the <code>serve</code> command will watch for changes automatically. To disable this, you can use <code>jekyll serve --no-watch</code>, which preserves the old behavior.
</p>
</div>
```sh
$ jekyll serve --no-watch
# => Same as `jekyll serve` but will not watch for changes.
```
These are just a few of the available [configuration options](../configuration/).
Many configuration options can either be specified as flags on the command line,
or alternatively (and more commonly) they can be specified in a `_config.yml`
file at the root of the source directory. Jekyll will automatically use the
options from this file when run. For example, if you place the following lines
in your `_config.yml` file:
```yaml
source: _source
destination: _deploy
```
Then the following two commands will be equivalent:
```sh
$ jekyll build
$ jekyll build --source _source --destination _deploy
```
For more about the possible configuration options, see the
[configuration](../configuration/) page.
<div class="note info">
<h5>Call for help</h5>
<p>
The <code>help</code> command is always here to remind you of all available options and usage, and also works with the <code>build</code>, <code>serve</code> and <code>new</code> subcommands, e.g <code>jekyll help new</code> or <code>jekyll help build</code>.
</p>
</div>
If you're interested in browsing these docs on-the-go, install the
`jekyll-docs` gem and run `jekyll docs` in your terminal.

title: Variables
permalink: /docs/variables/

Jekyll traverses your site looking for files to process. Any files with [YAML
front matter](../frontmatter/) are subject to processing. For each of these
files, Jekyll makes a variety of data available via the [Liquid templating
system](https://github.com/Shopify/liquid/wiki). The
following is a reference of the available data.

title: Jekyll on Windows
permalink: /docs/windows/
---
While Windows is not an officially-supported platform, it can be used to run Jekyll with the proper tweaks. This page aims to collect some of the general knowledge and lessons that have been unearthed by Windows users.
## Installing Jekyll
If you are using Windows 10 Anniversary Update, the easiest way to run Jekyll is by [installing][WSL-Guide] the new Bash on Ubuntu on Windows.
### Installation via Bash on Windows 10
*Note:* You must have [Bash on Ubuntu on Windows][BASH-WSL] enabled.
First let's make sure all our packages / repositories are up to date. Open a new Command Prompt instance, and type the following:
```
bash
```
Your Command Prompt instance should now be a Bash instance. Now we must update our repo lists and packages.
```
sudo apt-get update -y && sudo apt-get upgrade -y
```
Now we can install Ruby. To do this we will use a repository from [BrightBox](https://www.brightbox.com/docs/ruby/ubuntu/), which hosts optimized versions of Ruby for Ubuntu.
```
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get install ruby2.3 ruby2.3-dev build-essential
```
Next let's update our Ruby gems:
```
sudo gem update
```
Now all that is left to do is install Jekyll.
```
sudo gem install jekyll bundler
```
Check if Jekyll installed properly by running:
```
jekyll -v
```
**And that's it!**
To start a new project named `my_blog`, just run:
```
jekyll new my_blog
```
You can make sure time management is working properly by inspecting your `_posts` folder. You should see a markdown file with the current date in the filename.
**Note:** Bash on Ubuntu on Windows is still under development, so you may run into issues.
[WSL-Guide]: https://msdn.microsoft.com/en-us/commandline/wsl/install_guide
[BASH-WSL]: https://msdn.microsoft.com/en-us/commandline/wsl/about
### Installation via RubyInstaller
[RubyInstaller][] is a self-contained Windows-based installer that includes the Ruby language, an execution environment, important documentation, and more.
1. Download and Install a package manager version from [RubyInstaller Downloads][RubyInstaller-downloads].
2. Install Jekyll and Bundler via a command prompt window: `gem install jekyll bundler`
3. Check if Jekyll installed properly: `jekyll -v`
[RubyInstaller]: https://rubyinstaller.org/
[RubyInstaller-downloads]: https://rubyinstaller.org/downloads/
### Installation via Chocolatey
A quick way to install Jekyll using Chocolatey is to follow the [installation instructions by David Burela](https://davidburela.wordpress.com/2015/11/28/easily-install-jekyll-on-windows-with-3-command-prompt-entries-and-chocolatey/):
1. Install a package manager for Windows called [Chocolatey][]
2. Install Ruby via Chocolatey: `choco install ruby -y`
3. Reopen a command prompt and install Jekyll: `gem install jekyll`
Updates in the infrastructure of Ruby may cause SSL errors when attempting to use `gem install` with versions of the RubyGems package older than 2.6. (The RubyGems package installed via the Chocolatey tool is version 2.3) If you have installed an older version, you can update the RubyGems package using the directions [here][ssl-certificate-update].
[ssl-certificate-update]: http://guides.rubygems.org/ssl-certificate-update/#installing-using-update-packages
### Installing *github-pages* via Chocolatey
This section is part of an article written by [Jens Willmer][jwillmerPost]. To follow the instructions you need to have [Chocolatey][] installed on your system. If you already have a version of Ruby installed you need to uninstall it before you can continue.
#### Install Ruby and Ruby development kit
Open a command prompt and execute the following commands:
* `choco install ruby -version 2.2.4`
* `choco install ruby2.devkit` - _needed for compilation of json gem_
#### Configure Ruby development kit
The development kit did not set the environment path for Ruby so we need to do it.
* Open command prompt in `C:\tools\DevKit2`
* Execute `ruby dk.rb init` to create a file called `config.yml`
* Edit the `config.yml` file and include the path to Ruby `- C:/tools/ruby22`
* Execute the following command to set the path: `ruby dk.rb install`
#### Nokogiri gem installation
This gem is also needed in the github-pages and to get it running on Windows x64 we have to install a few things.
**Note:** In the current [pre release][nokogiriFails] it works out of the box with Windows x64 but this version is not referenced in the github-pages.
`choco install libxml2 -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
`choco install libxslt -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
`choco install libiconv -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
```ruby
gem install nokogiri --^
--with-xml2-include=C:\Chocolatey\lib\libxml2.2.7.8.7\build\native\include^
--with-xml2-lib=C:\Chocolatey\lib\libxml2.redist.2.7.8.7\build\native\bin\v110\x64\Release\dynamic\cdecl^
--with-iconv-include=C:\Chocolatey\lib\libiconv.1.14.0.11\build\native\include^
--with-iconv-lib=C:\Chocolatey\lib\libiconv.redist.1.14.0.11\build\native\bin\v110\x64\Release\dynamic\cdecl^
--with-xslt-include=C:\Chocolatey\lib\libxslt.1.1.28.0\build\native\include^
--with-xslt-lib=C:\Chocolatey\lib\libxslt.redist.1.1.28.0\build\native\bin\v110\x64\Release\dynamic
```
#### Install github-pages
* Open command prompt and install [Bundler][]: `gem install bundler`
* Create a file called `Gemfile` without any extension in your root directory of your blog
* Copy & paste the two lines into the file:
```ruby
source 'https://rubygems.org'
gem 'github-pages', group: :jekyll_plugins
```
* **Note:** We use an unsecure connection because SSL throws exceptions in the version of Ruby
* Open a command prompt, target your local blog repository root, and install github-pages: `bundle install`
After this process you should have github-pages installed on your system and you can host your blog again with `jekyll s`.
There will be a warning on startup that you should include `gem 'wdm', '>= 0.1.0' if Gem.win_platform?` to your `Gemfile` but I could not get `jekyll s` working if I include that line so for the moment I ignore that warning.
In the future the installation process of the github-pages should be as simple as the setup of the blog. But as long as the new version of the Nokogiri ([v1.6.8][nokogiriReleases]) is not stable and referenced, it is work to get it up and running on Windows.

For a more conventional way of installing Jekyll you can follow this [complete guide to install Jekyll 3 on Windows by Sverrir Sigmundarson][windows-installjekyll3].
Optionally you can use [Autoinstall Jekyll for Windows][fastjekyll-autoinstall].
---
[windows-installjekyll3]: https://labs.sverrirs.com/jekyll/
[fastjekyll-autoinstall]: https://github.com/KeJunMao/fastjekyll#autoinstall-jekyll-for-windows
## Encoding
If you use UTF-8 encoding, make sure that no `BOM` header characters exist in your files or very, very bad things will happen to
Jekyll. This is especially relevant when you're running Jekyll on Windows.
Additionally, you might need to change the code page of the console window to UTF-8 in case you get a "Liquid Exception: Incompatible character encoding" error during the site generation process. It can be done with the following command:
```sh
$ chcp 65001
```
## Time-Zone Management
Since Windows doesn't have a native source of zoneinfo data, the Ruby Interpreter would not understand IANA Timezones and hence using them had the `TZ` environment variable default to UTC/GMT 00:00.
Though Windows users could alternatively define their blog's timezone by setting the key to use POSIX format of defining timezones, it wasn't as user-friendly when it came to having the clock altered to changing DST-rules.
Jekyll now uses a rubygem to internally configure Timezone based on established [IANA Timezone Database][IANA-database].
While 'new' blogs created with Jekyll v3.4 and greater, will have the following added to their 'Gemfile' by default, existing sites *will* have to update their 'Gemfile' (and installed) to enable development on Windows:
```ruby
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
```
[IANA-database]: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
## Auto Regeneration
As of v1.3.0, Jekyll uses the `listen` gem to watch for changes when the `--watch` switch is specified during a build or serve. While `listen` has built-in support for UNIX systems, it may require an extra gem for compatibility with Windows.
Add the following to the Gemfile for your site if you have issues with auto-regeneration on Windows alone:
```ruby
gem 'wdm', '~> 0.1.0' if Gem.win_platform?
```
