-# 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
-
-See [the support guidelines](https://jekyllrb.com/docs/support/)
-
-## 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).
-
-* You can use the command `script/console` to start a REPL to explore the result of
-Jekyll's methods. It also provides you with helpful methods to quickly create a
-site or configuration. [Feel free to check it out!](https://github.com/jekyll/jekyll/blob/master/script/console)
-
-## 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:
-
-```sh
-script/bootstrap
-```
-
-Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
-
-```sh
-script/cibuild
-```
-
-If you are only updating a file in `test/`, you can use the command:
-
-```sh
-script/test test/blah_test.rb
-```
-
-If you are only updating a `.feature` file, you can use the command:
-
-```sh
-script/cucumber features/blah.feature
-```
-
-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.
-
-  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 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 occurred 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.

CONTRIBUTING.markdown

@@ -0,0 +1,91 @@
+Contribute
+==========
+
+So you've got an awesome idea to throw into Jekyll. Great! Please keep the
+following in mind:
+
+* **Contributions will not be accepted without tests or necessary documentation updates.**
+* If you're creating a small fix or patch to an existing feature, just a simple
+  test will do. Please stay in the confines of the current test suite and use
+  [Shoulda](https://github.com/thoughtbot/shoulda/tree/master) and
+  [RR](https://github.com/rr/rr).
+* If it's a brand new feature, make sure to create a new
+  [Cucumber](https://github.com/cucumber/cucumber/) feature and reuse steps
+  where appropriate. Also, whipping up some documentation in your fork's `site`
+  would be appreciated, and once merged it will be transferred over to the main
+  `site`, jekyllrb.com.
+* If your contribution changes any Jekyll behavior, make sure to update the
+  documentation. It lives in `site/docs`. If the docs are missing information,
+  please feel free to add it in. Great docs make a great project!
+* Please follow the [GitHub Ruby Styleguide](https://github.com/styleguide/ruby)
+  when modifying Ruby code.
+* Please do your best to submit **small pull requests**. The easier the proposed
+  change is to review, the more likely it will be merged.
+* When submitting a pull request, please make judicious use of the pull request
+  body. A description of what changes were made, the motivations behind the
+  changes and [any tasks completed or left to complete](http://git.io/gfm-tasks)
+  will also speed up review time.
+
+Test Dependencies
+-----------------
+
+To run the test suite and build the gem you'll need to install Jekyll's
+dependencies. Jekyll uses Bundler, so a quick run of the bundle command and
+you're all set!
+
+    $ bundle
+
+Before you start, run the tests and make sure that they pass (to confirm your
+environment is configured properly):
+
+    $ bundle exec rake test
+    $ bundle exec rake features
+
+Workflow
+--------
+
+Here's the most direct way to get your work merged into the project:
+
+* Fork the project.
+* Clone down your fork ( `git clone git@github.com:<username>/jekyll.git` ).
+* Create a topic branch to contain your change ( `git checkout -b my_awesome_feature` ).
+* Hack away, add tests. Not necessarily in that order.
+* Make sure everything still passes by running `rake`.
+* If necessary, rebase your commits into logical chunks, without errors.
+* Push the branch up ( `git push origin my_awesome_feature` ).
+* Create a pull request against jekyll/jekyll and describe what your change
+  does and the why you think it should be merged.
+
+Updating 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.
+
+You can find the documentation for jekyllrb.com in the
+[site](https://github.com/jekyll/jekyll/tree/master/site) directory of
+Jekyll's repo on GitHub.com.
+
+All documentation pull requests should be directed at `master`.  Pull
+requests directed at another branch will not be accepted.
+
+The [Jekyll wiki](https://github.com/jekyll/jekyll/wiki) on GitHub
+can be freely updated without a pull request as all GitHub users have access.
+
+Gotchas
+-------
+
+* If you want to bump the gem version, please put that in a separate commit.
+  This way, the maintainers can control when the gem gets released.
+* Try to keep your patch(es) based from the latest commit on jekyll/jekyll.
+  The easier it is to apply your work, the less work the maintainers have to do,
+  which is always a good thing.
+* Please don't tag your GitHub issue with [fix], [feature], etc. The maintainers
+  actively read the issues and will label it once they come across it.
+
+Finally...
+----------
+
+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!

-#
-# The Ruby documentation for #sort_by describes what's called a Schwartzian transform:
-#
-#  > A more efficient technique is to cache the sort keys (modification times in this case)
-#  > before the sort. Perl users often call this approach a Schwartzian transform, after
-#  > Randal Schwartz. We construct a temporary array, where each element is an array
-#  > containing our sort key along with the filename. We sort this array, and then extract
-#  > the filename from the result.
-#  > This is exactly what sort_by does internally.
-#
-# The well-documented efficiency of sort_by is a good reason to use it. However, when a property
-# does not exist on an item being sorted, it can cause issues (no nil's allowed!)
-# In Jekyll::Filters#sort_input, we extract the property in each iteration of #sort,
-# which is quite inefficient! How inefficient? This benchmark will tell you just how, and how much
-# it can be improved by using the Schwartzian transform. Thanks, Randall!

-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
-```

-  <h5>Gather your collections {%- include docs_version_badge.html version="3.7.0" -%}</h5>
-
-  <p>You can optionally specify a directory to store all your collections in the same place with <code>collections_dir: my_collections</code>.</p>
-
-  <p>Then Jekyll will look in <code>my_collections/_books</code> for the <code>books</code> collection, and
-  in <code>my_collections/_recipes</code> for the <code>recipes</code> collection.</p>
-</div>
-
-<div class="note warning">
-  <h5>Be sure to move posts into custom collections directory</h5>
-
-  <p>If you specify a directory to store all your collections in the same place with <code>collections_dir: my_collections</code>, then you will need to move your <code>_posts</code> directory to <code>my_collections/_posts</code>. Note that, the name of your collections directory cannot start with an underscore (`_`).</p>
-</div>
-
-### 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`.
-
-If you wish a specific page to be shown when accessing `/my_collection/`,
-simply add `permalink: /my_collection/index.html` to a page.
-To list items from the collection, on that page or any other, you can use:
-
-{% raw %}
-```liquid
-{% for item in site.my_collection %}
-  <h2>{{ item.title }}</h2>
-  <p>{{ item.description }}</p>
-  <p><a href="{{ item.url }}">{{ item.title }}</a></p>
-{% endfor %}
-```
-{% endraw %}
-
-<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/`.

-## 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:
-
-```liquid
-{% 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 %}

-title: "Buddy"
----
-
-[Buddy][buddy-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.
-
-[buddy-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][buddy-homepage] 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:
-
-```yaml
-- 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 Buddy 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
-
-```ruby
-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.
-
-```yaml
-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:
-
-```yaml
-machine:
-  environment:
-    NOKOGIRI_USE_SYSTEM_LIBRARIES: true # speeds up installation of html-proofer

-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
-
-See [the support guidelines](https://jekyllrb.com/docs/support/)
-
-## 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).
-
-* You can use the command `script/console` to start a REPL to explore the result of
-Jekyll's methods. It also provides you with helpful methods to quickly create a
-site or configuration. [Feel free to check it out!](https://github.com/jekyll/jekyll/blob/master/script/console)
-
-## 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:
-
-```sh
-script/bootstrap
-```
-
-Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
-
-```sh
-script/cibuild
-```
-
-If you are only updating a file in `test/`, you can use the command:
-
-```sh
-script/test test/blah_test.rb
-```
-
-If you are only updating a `.feature` file, you can use the command:
-
-```sh
-script/cucumber features/blah.feature
-```
-
-Both `script/test` and `script/cucumber` can be run without arguments to
-run its entire respective suite.
-
-## A thank you

-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.
-
-<div class="note">

-
-## Netlify
-
-Netlify provides Global CDN, Continuous Deployment, one click HTTPS and [much more](https://www.netlify.com/features/), providing developers the most robust toolset available for modern web projects, without added complexity. Netlify supports custom plugins for Jekyll and has a free plan for open source projects.
-
-Read this [Jekyll step-by-step guide](https://www.netlify.com/blog/2015/10/28/a-step-by-step-guide-jekyll-3.0-on-netlify/) to setup your Jekyll site on Netlify.
-
-## Aerobatic
-
-[Aerobatic](https://www.aerobatic.com) has custom domains, global CDN distribution, basic auth, CORS proxying, and a growing list of plugins all included.
-
-Automating the deployment of a Jekyll site is simple. See their [Jekyll docs](https://www.aerobatic.com/docs/static-site-generators/#jekyll) for more details. Your built `_site` folder is deployed to their highly-available, globally distributed hosting service.
-
-## Kickster
-
-Use [Kickster](http://kickster.nielsenramon.com/) for easy (automated) deploys to GitHub Pages when using unsupported plugins on GitHub Pages.
-
-Kickster provides a basic Jekyll project setup packed with web best practises and useful optimization tools increasing your overall project quality. Kickster ships with automated and worry-free deployment scripts for GitHub Pages.
-
-Setting up Kickster is very easy, just install the gem and you are good to go. More documentation can here found [here](https://github.com/nielsenramon/kickster#kickster). If you do not want to use the gem or start a new project you can just copy paste the deployment scripts for [Travis CI](https://github.com/nielsenramon/kickster/tree/master/snippets/travis) or [Circle CI](https://github.com/nielsenramon/kickster#automated-deployment-with-circle-ci).
-
-## 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 you’ve got another method that isn’t listed below, we’d 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?), it’s 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:
-
-```bash
-GIT_REPO=$HOME/myrepo.git
-TMP_GIT_CLONE=$HOME/tmp/myrepo
-GEMFILE=$TMP_GIT_CLONE/Gemfile
-PUBLIC_WWW=/var/www/myrepo
-
-git clone $GIT_REPO $TMP_GIT_CLONE
-BUNDLE_GEMFILE=$GEMFILE bundle install
-BUNDLE_GEMFILE=$GEMFILE bundle exec 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 you’ve generated the `_site` directory, you can easily scp its content using a
-`tasks/deploy` shell script similar to [this deploy script][]. You’d obviously
-need to change the values to reflect your site’s 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 you’ve 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). You’d obviously need to change the values to reflect your site’s 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-Admin’s [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).

-
-[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 they're a great way to host your Jekyll-powered
-website for free.
-
-Your site is automatically generated by GitHub Pages when you push your source
-files. Note that GitHub Pages works equally well for regular HTML content,
-simply because Jekyll treats files without YAML front matter as static assets.
-So if you only need to push generated HTML, you're good to go without any
-further setup.
-
-Never built a website with GitHub Pages before? [See this marvelous guide by
-Jonathan McGlone](http://jmcglone.com/guides/github-pages/) to get you up and
-running. This guide will teach you what you need to know about Git, GitHub, and
-Jekyll to create your very own website on GitHub Pages.
-
-##  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](https://pages.github.com/versions/).
-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.
-
-Note that GitHub Pages runs in `safe` mode and only allows [a set of whitelisted
-plugins](https://help.github.com/articles/configuring-jekyll-plugins/#default-plugins).
-
-To use the currently-deployed version of the gem in your project, add the
-following to your `Gemfile`:
-
-```ruby
-source "https://rubygems.org"
-
-gem "github-pages", group: :jekyll_plugins
-```
-
-Be sure to run `bundle update` often.
-
-<div class="note">
-  <h5>GitHub Pages Documentation, Help, and Support</h5>

-### 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 the handy [URL filters](../templates/#filters):
-
-{% raw %}
-```liquid
-<!-- For styles with static names... -->
-<link href="{{ "/assets/css/style.css" | relative_url }}" rel="stylesheet">
-<!-- For documents/pages whose URLs can change... -->
-[{{ page.title }}]("{{ page.url | relative_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 and project pages](https://help.github.com/articles/user-organization-and-project-pages/).
-The way to deploy these two types of sites are nearly identical, except for a
-few minor details.
-
-### 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, [@mojombo’s 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

-title: Includes
-permalink: /docs/includes/
----
-
-The `include` tag allows you to include the content from another file stored in the `_includes` folder:
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-<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:
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-<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`):
-
-{% raw %}
-```liquid
-{% 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://shopify.github.io/liquid/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:
-
-{% raw %}
-```liquid
-{% 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):
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-{% 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 %}
-```liquid
-{% 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. We’ll cover topics such as getting your site up and running, creating and managing content, customizing your build, and deploying.
-
-## What is Jekyll, exactly?
-
-Jekyll is a simple, blog-aware, static site generator.
-
-You create your content as text files ([Markdown](https://daringfireball.net/projects/markdown/)), and organize them into folders. Then, you build the shell of your site using [Liquid](https://shopify.github.io/liquid/)-enhanced HTML templates. Jekyll automatically stitches the content and templates together, generating a website made entirely of static assets, suitable for uploading to any server.
-
-Jekyll happens to be the engine behind [GitHub Pages](https://pages.github.com), so you can host your project’s Jekyll page/blog/website on GitHub’s servers **for free**.
-
-## Navigating the Guide
-
-Throughout this guide, you'll see these special sections that help you get the most out of Jekyll:

-title: Installation
-description: Official guide to install Jekyll on macOS, GNU/Linux or Windows.
-permalink: /docs/installation/
----
-
-Jekyll is a [Ruby Gem](http://guides.rubygems.org/rubygems-basics/), and can be
-installed on most systems.
-
-- [Requirements](#requirements)
-- [Install Jekyll on macOS](#macOS)
-- [Install Jekyll on Ubuntu Linux](#ubuntu)
-- [Install Jekyll on Windows](../windows/)
-- [Upgrade Jekyll](#upgrade-jekyll)
-
-## Requirements
-
-Before you start, make sure your system has the following:
-
-- [Ruby](https://www.ruby-lang.org/en/downloads/) version 2.2.5 or above, including all development headers (ruby installation can be checked by running `ruby -v`)
-- [RubyGems](https://rubygems.org/pages/download) (which you can check by running `gem -v`)
-- [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`,`g++ -v`  and `make -v` in your system's command line interface)
-
-## Install on macOS {#macOS}
-
-We only cover macOS High Sierra 10.13 here, which comes with Ruby 2.3.3, older systems will need to [install a more recent Ruby version via Homebrew](#homebrew).
-
-First, you need to install the command-line tools to be able to compile native extensions, open a terminal and run:
-
-```sh
-xcode-select --install
-```
-
-### Set up Ruby included with the OS
-
-Check your Ruby version meet our requirements:
-
-```sh
-ruby -v
-2.3.3
-```
-
-Great, let's install Jekyll. We also need [Bundler](https://bundler.io/) to help us handle [plugins](../plugins) and [themes](../themes):
-
-```sh
-gem install bundler jekyll
-```
-
-That's it, you're ready to go, either by installing our [default minimal blog theme](https://github.com/jekyll/minima) with `jekyll new jekyll-website` or by starting from scratch:
-
-```sh
-mkdir jekyll-website
-cd jekyll-website
-
-# Create a Gemfile
-bundle init
-
-# Add Jekyll
-bundle add jekyll
-
-# Install gems
-bundle install
-```
-
-Great, from there you can now either use a [theme](../themes/) or [create your own layouts](../templates/).
-
-### Install a newer Ruby version via Homebrew {#homebrew}
-
-If you wish to install the latest version of Ruby and get faster builds, we recommend to do it via [Homebrew](https://brew.sh) a handy package manager for macOS.
-
-```sh
-/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-brew install ruby
-ruby -v
-ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
-```
-
-Yay! Now you have a shiny Ruby on your system!
-
-### Install multiple Ruby versions with rbenv {#rbenv}
-
-Developers often use [rbenv](https://github.com/rbenv/rbenv) to manage multiple Ruby versions. This can be useful if you want to run the same Ruby version used by [GitHub Pages](https://pages.github.com/versions/) or [Netlify](https://www.netlify.com/docs/#ruby) for instance.
-
-```sh
-# Install rbenv and ruby-build
-brew install rbenv
-
-# Setup rbenv integration to your shell
-rbenv init
-
-# Check your install
-curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash
-```
-
-Restart your terminal for changes to take effect.
-Now we can install the Ruby version of our choice, let's go with Ruby 2.5.1 here:
-
-```sh
-rbenv install 2.5.1
-rbenv global 2.5.1
-ruby -v
-ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
-```
-
-That's it! Head over [rbenv command references](https://github.com/rbenv/rbenv#command-reference) to learn how to use different versions of Ruby in your projects.

-##### Problems installing Jekyll?
-
-Check out the [troubleshooting](../troubleshooting/) page or
-[ask for help on our forum](https://talk.jekyllrb.com).
-
-</div>
-
-## Install on Ubuntu Linux {#ubuntu}
-
-Before we install Jekyll, we need to make sure we have all the required
-dependencies.
-
-```sh
-sudo apt-get install ruby ruby-dev build-essential
-```
-
-It is best to avoid installing Ruby Gems as the root user. Therefore, we need to
-set up a gem installation directory for your user account. The following
-commands will add environment variables to your `~/.bashrc` file to configure
-the gem installation path. Run them now:
-
-```sh
-echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
-echo 'export GEM_HOME=$HOME/gems' >> ~/.bashrc
-echo 'export PATH=$HOME/gems/bin:$PATH' >> ~/.bashrc
-source ~/.bashrc
-```
-
-Finally, install Jekyll:
-
-```sh
-gem install jekyll bundler
-```
-
-That's it! You're ready to start using Jekyll.
-
-## Upgrade Jekyll
-
-Before you start developing with Jekyll, you may want to check that you're up to date with the latest version. To find the currently installed version of Jekyll, run one of these commands:
-
-```sh
-jekyll --version
-gem list jekyll
-```
-
-You can use RubyGems to find [the current version of Jekyll](https://rubygems.org/gems/jekyll). 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
-bundle update jekyll
-```
-
-Alternatively, if you don't have Bundler installed run:
-
-```sh
-gem update jekyll
-```
-
-To upgrade to latest Rubygems, run:
-
-```
-gem update --system
-```
-
-Refer to our [upgrading section](../upgrading/) to upgrade from Jekyll 2.x or 1.x.
-
-## 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
-```
-
-Now that you’ve got everything up-to-date and installed, let’s 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 it’s 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 it’s 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 at some point decide to stop using Jekyll, and at that point you should also decide to stop being 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 at a job). We may still ask for your help with questions after you leave but you are under no obligation to answer them. 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). Also, 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.

----

-{: .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.

-**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. We like to 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 headings in the `History.markdown` 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 (with the labels `feature` or `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:

-title: "Releasing a new version"
----
-
-**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 it’s definitely not for everyone.
-{: .note .info }
-
-The most important thing to understand before making a release is that there's no need to feel nervous. Most things are revertable, and even if you do publish an incomplete gem version, we can always skip that one. Don't hestitate to contact the other maintainers if you feel unsure or don't know what to do next.
-
-### Bump the version
-
-The only important place you need to manually bump the version is in `lib/jekyll/version.rb`. Adjust that, and everything else should work fine.
-
-### Update the history document
-
-Replace the first header of the history document with a version milestone. This looks like the following:
-
-```diff
--## HEAD
-+## 3.7.1 / 2018-01-25
-```
-
-Adjust the version number and the date. The `## HEAD` heading will be regenerated next time a pull request is merged.
-
-Once you've done this, update the website by running the following command:
-
-```sh
-bundle exec rake site:generate
-```
-
-This updates the website's changelog, and pushes the versions in various other places.
-
-It's recommended that you go over the `History.markdown` file manually one more time, in case there are any spelling errors or such. Feel free to fix those manually, and after you're done generating the website changelog, commit your changes.
-
-## Write a release post
-
-In case this isn't done already, you can generate a new release post using the included `rake` command:
-
-```sh
-bundle exec rake site:releases:new[3.8.0]
-```
-
-where `3.8.0` should be replaced with the new version. Then, write the post. Be sure to thank all of the collaborators and maintainers who have contributed since the last release. You can generate a log of their names using the following command:
-
-```sh
-git shortlog -sn master...v3.7.2
-```
-
-where, again `v3.7.2` is the last release. Be sure to open a pull request for your release post.
-
-### Push the version
-
-Before you do this step, make sure the following things are done:
-
-- You have permission to push a new gem version to RubyGems
-- You're logged into RubyGems on your command line
-- A release post has been prepared, and is ideally already live
-- All of the prior steps are done, committed, and pushed to `master`
-
-Really the only thing left to do is to run this command:
-
-```sh
-bundle exec rake release
-```
-
-This will automatically build the new gem, make a release commit and tag and then push the new gem to RubyGems. Don't worry about creating a GitHub release, @jekyllbot should take care of that.
-
-And then, you're done! :tada: Feel free to celebrate!
-
-If you have access to the [@jekyllrb](https://twitter.com/jekyllrb) Twitter account, you should tweet the release post from there. If not, just ask another maintainer to do it or to give you access.
-
-### Build the docs
-
-We package our documentation as a :gem: Gem for offline use.
-
-This is done with the
-[**jekyll-docs**](https://github.com/jekyll/jekyll-docs#building) repository,
-and more detailed instructions are provided there.
-
-## For non-core gems
-
-If you're not a maintainer for `jekyll/jekyll`, the procedure is much simpler in a lot of cases. Generally, the procedure still looks like this:
-
-- Bump the gem version manually, usually in `lib/<plugin_name>/version.rb`
-- Adjust the history file
-- Run `bundle exec rake release` or `script/release`, depending on which of the two exists
-- Rejoice
-
-Be sure to ask your project's maintainers if you're unsure!

-
-## 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.

-**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 it’s 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)

-{: .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 you’re 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, here’s 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:
-
-```yaml
----
-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: 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:output_ext`. 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:output_ext
-```
-
-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:output_ext`, 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.

-            except numbers and letters is replaced as hyphen). May be
-            overridden via the document’s <code>slug</code> YAML front matter.

-        <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>

-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:output_ext</code></p>

-    </tr>
-    <tr>
-      <td>

-      </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>

-
-## 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">
-<table>
-  <thead>
-    <tr>

-## 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:output_ext` 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 (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:
-
-```yaml
----
-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.

-
-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 won’t work if you’re deploying to GitHub Pages.<br><br>
-    You can still use GitHub Pages to publish your site, but you’ll 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` (or `gems` for Jekyll < `3.5.0`) and the
-   values of the gem names of the plugins you'd like to use. An example:
-
-   ```yaml
-   # This will require each of these plugins automatically.
-   plugins:
-     - jekyll-gist
-     - jekyll-coffeescript
-     - jekyll-assets
-     - another-jekyll-plugin
-   ```
-
-   Then install your plugins using `gem install jekyll-gist jekyll-coffeescript jekyll-assets another-jekyll-plugin`
-
-3. Add the relevant plugins to a Bundler group in your `Gemfile`. An
-   example:
-
-   ```ruby
-    group :jekyll_plugins do
-      gem "jekyll-gist"
-      gem "jekyll-coffeescript"
-      gem "jekyll-assets"
-      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>
-
-### The jekyll_plugins group
-
-Jekyll gives this particular group of gems in your `Gemfile` a different
-treatment. Any gem included in this group is loaded before Jekyll starts
-processing the rest of your source directory.
-
-A gem included here will be activated even if its not explicitly listed under
-the `plugins:` key in your site's config file.
-
-<div class="note warning">
-  <p>
-    Gems included in the <code>:jekyll-plugins</code> group are activated
-    regardless of the <code>--safe</code> mode setting. Be aware of what
-    gems are included under this group!
-  </p>
-</div>
-
-
-In general, plugins you make will fall broadly into one of five categories:
-
-1. [Generators](#generators)
-2. [Converters](#converters)
-3. [Commands](#commands)
-4. [Tags](#tags)
-5. [Hooks](#hooks)
-
-See the bottom of the page for a [list of available plugins](#available-plugins).
-
-For further information on how to develop your own plugins, check out the [Liquid documentation](https://github.com/Shopify/liquid/wiki/Liquid-for-Programmers) as well.
-
-If you never developed a Jekyll plugin [check this useful wrap-up](https://ayastreb.me/writing-a-jekyll-plugin/) by @ayastreb to get started.
-
-## 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 you’d 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 converter’s list of acceptable
-        extensions? Takes one argument: the file’s 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 we’re
-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 you’d 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:
-
-{% raw %}
-```ruby
-<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>

-          A boolean flag that informs Jekyll whether this plugin may be safely

-          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 won’t load your plugin, but if you submit it for
-          inclusion in core, it’s best for this to be correct!

-          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

-</div>
-
-To use one of the example plugins above as an illustration, here is how you’d
-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:

-title: Writing posts
-permalink: /docs/posts/
----
-
-One of Jekyll’s best aspects is that it is “blog aware”. What does this mean,
-exactly? Well, simply put, it means that blogging is baked into Jekyll’s
-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:
-
-```
-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:
-
-```
-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`, into which any images, files
-or other resources are placed. Then, from within any post, they can be linked
-to using the site’s root as the path for the asset to include. Again, this will
-depend on the way your site’s (sub)domain and path are configured, but here are
-some examples in Markdown of how you could do this using the `absolute_url`
-filter in a post.
-
-Including an image asset in a post:
-
-{% raw %}
-```markdown
-... which is shown in the screenshot below:
-![My helpful screenshot]({{ "/assets/screenshot.jpg" | absolute_url }})
-```
-{% endraw %}
-
-Linking to a PDF for readers to download:
-
-{% raw %}
-```markdown
-... you can [get the PDF]({{ "/assets/mydoc.pdf" | absolute_url }}) directly.
-```
-{% endraw %}
-
-<div class="info">
-
-</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:
-
-```markdown
----
-layout: post
-title:  "Welcome to Jekyll!"
-date:   2015-11-17 16:16:01 -0600
-categories: jekyll update
----
-
-You’ll 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
-
-It’s 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. Here’s a
-basic example of how to create a list of links to your blog posts:
-
-{% raw %}
-```html
-<ul>
-  {% for post in site.posts %}
-    <li>
-      <a href="{{ post.url }}">{{ post.title }}</a>
-    </li>
-  {% endfor %}
-</ul>
-```
-{% endraw %}
-
-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.
-
-## Displaying post categories or tags
-
-Hey, that's pretty neat, but what about showing just some of your posts that are
-related to each other? For that you can use any of the [variables definable in
-Front Matter](https://jekyllrb.com/docs/frontmatter/). In the "typical post"
-section you can see how to define categories. Simply add the categories to your
-Front Matter as a [yaml
-list](https://en.wikipedia.org/wiki/YAML#Basic_components).
-
-Now that your posts have a category or multiple categories, you can make a page
-or a template displaying just the posts in those categories you specify. Here's
-a basic example of how to create a list of posts from a specific category.
-
-First, in the `_layouts` directory create a new file called `category.html` - in
-that file put (at least) the following:
-
-{% raw %}
-```liquid
----
-layout: page
----
-
-{% for post in site.categories[page.category] %}
-    <a href="{{ post.url | absolute_url }}">
-      {{ post.title }}
-    </a>
-{% endfor %}
-```
-{% endraw %}
-
-Next, in the root directory of your Jekyll install, create a new directory
-called `category` and then create a file for each category you want to list. For
-example, if you have a category `blog` then create a file in the new directory
-called `blog.html` with at least
-
-```yaml
----
-layout: category
-title: Blog
-category: blog
----
-```
-
-In this case, the listing pages will be accessible at `{baseurl}/category/blog.html`
-
-Although categories and tags are very similar, they are used to group posts,
-there are a few differences between them.  Categories and sub-categories create
-hierarchies that, by default, are reflected in the directory structure of your
-site.  A post with the following header
-```yaml
----
-layout: post
-title: A Trip
-category: [ blog, travel ]
----
-```
-will be accessible at `{baseurl}/blog/travel/year/month/day/A-Trip.html`.  On
-the other hand, a tagged post
-```yaml
----
-layout: post
-title: A Trip
-tags: [ blog, travel ]
----
-```
-will be saved as `{baseurl}/year/month/day/A-Trip.html`.  It is up to you to
-create `{baseurl}/tag/blog.html` and `{baseurl}/tag/travel.html` the same way as
-described above for categories.
-
-While this example is done with tags and categories, you can easily extend your
-lists to filter by any other variable created with extensions.
-
-## 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 in the
-post's data hash.
-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:
-
-{% raw %}
-```liquid
-<ul>
-  {% for post in site.posts %}
-    <li>
-      <a href="{{ post.url }}">{{ post.title }}</a>
-      {{ post.excerpt }}
-    </li>
-  {% endfor %}
-</ul>
-```
-{% endraw %}
-
-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:
-
-{% raw %}
-```liquid
-{{ 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:
-
-```yaml
----
-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:
-
-{% raw %}
-```liquid
-{% highlight ruby %}
-def show
-  @widget = Widget(params[:id])
-  respond_to do |format|
-    format.html # show.html.erb
-    format.json { render json: @widget }
-  end
-end
-{% 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
-you’re 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.

-## About Bundler
-
-`gem install bundler` installs the [bundler](https://rubygems.org/gems/bundler) gem through [RubyGems](https://rubygems.org/). You only need to install it once — 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.
-
-For more information about how to use Bundler in your Jekyll project, this [tutorial](https://jekyllrb.com/tutorials/using-jekyll-with-bundler/) should provide answers to the most common questions and explain how to get up and running quickly.
- 
-## 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>.

-## 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:
-
-{% raw %}
-```liquid
-{% 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.

-### 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 `._~!$&'()+,;=@`
-- `ascii`: spaces, non-alphanumeric, and non-ASCII characters
-- `latin`: like `default`, except Latin characters are first transliterated (e.g. `àèïòü` to `aeiou`) {%- include docs_version_badge.html version="3.7.0" -%}

-* [Code snippet highlighting](#code-snippet-highlighting)
-* [Linking to pages, collections and posts (the new and improved way)](#links)
-* [Linking to posts (the old way)](#linking-to-posts)
-
-### 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:
-
-{% raw %}
-```liquid
-{% 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:
-
-{% raw %}
-```liquid
-{% 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/).
-
-<div class="note info">
-  <h5>Jekyll processes all Liquid filters in code blocks</h5>
-  <p>If you are using a language that contains curly braces, you
-    will likely need to place <code>{&#37; raw &#37;}</code> and
-    <code>{&#37; endraw &#37;}</code> tags around your code.</p>
-</div>
-
-#### 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:
-
-{% raw %}
-```liquid
-{% highlight ruby linenos %}
-def foo
-  puts 'foo'
-end
-{% endhighlight %}
-```
-{% endraw %}
-
-#### Stylesheets for syntax highlighting
-
-In order for the highlighting to show up, you’ll 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.
-
-
-## 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:
-
-{% raw %}
-```liquid
-{{ 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:
-
-{% raw %}
-```liquid
-[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` or `post_url` 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.
-
-The name of the file you want to link 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 link:
-
-```liquid
-{% raw %}{% link {{ page.my_variable }} %}{% endraw %}
-```
-
-In this example, the link would add link to the file `footer_company_a.html`.
-
-### 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.
-
-{% raw %}
-```liquid
-{{ 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:
-
-{% raw %}
-```liquid
-{{ 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:
-
-{% raw %}
-```liquid
-[Name of Link]({{ site.baseurl }}{% post_url 2010-07-21-name-of-post %})
-```
-{% endraw %}

-Jekyll has an extensive theme system that allows you to leverage community-maintained templates and styles to customize your site's presentation. Jekyll themes specify plugins and package up assets, 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:
-
-   ```sh
-   # 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 you must tell Jekyll about the plugins that were referenced by the theme. You can find these plugins in the theme's gemspec file as runtime dependencies. If you were converting the Minima theme, for example, you might see:
-
-```
-spec.add_runtime_dependency "jekyll-feed", "~> 0.9"
-spec.add_runtime_dependency "jekyll-seo-tag", "~> 2.1"
-```
-
-You should include these references in the `Gemfile` in one of two ways.
-
-You could list them individually in both `Gemfile` and `_config.yml`.
-
-```ruby
-# ./Gemfile
-
-gem "jekyll-feed", "~> 0.9"
-gem "jekyll-seo-tag", "~> 2.1"
-```
-
-```yaml
-# ./_config.yml
-
-plugins:
-  - jekyll-feed
-  - jekyll-seo-tag
-```
-
-Or you could list them explicitly as Jekyll plugins in your Gemfile, and not update `_config.yml`, like this:
-
-```ruby
-# ./Gemfile
-
-group :jekyll_plugins do
-  gem "jekyll-feed", "~> 0.9"
-  gem "jekyll-seo-tag", "~> 2.1"
-end
-```
-
-Either way, don't forget to `bundle update`.
-
-However, if you're publishing on GitHub Pages you should update only your `_config.yml` as GitHub Pages doesn't load plugins via Bundler.
-
-Finally, 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`:
-
-   ```ruby
-   # ./Gemfile
-
-   gem "jekyll-theme-awesome"
-   ```
-  Or if you've started with the `jekyll new` command, replace `gem "minima", "~> 2.0"` with your theme-gem:
-
-   ```diff
-   # ./Gemfile
-
-   - gem "minima", "~> 2.0"
-   + 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:
-
-   ```yaml
-   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.
-
-{% raw %}
-```css
-@import "{{ site.theme }}";
-```
-{% endraw %}
-
-### Theme-gem dependencies {%- include docs_version_badge.html version="3.5.0" -%}
-
-Jekyll will automatically require all whitelisted `runtime_dependencies` of your theme-gem even if they're not explicitly included under the `plugins` 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 programmatically. 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.

-
-## 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 Arch Linux you need to run:
-
-```sh
-sudo pacman -S ruby-ffi
-```
-
-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=$PATH:/home/private/gems/bin
-export RB_USER_INSTALL='true'
-```
-
-To install RubyGems on Gentoo:
-
-```sh
-sudo emerge -av dev-ruby/rubygems
-```
-
-On Windows, you may need to install [RubyInstaller
-DevKit](https://wiki.github.com/oneclick/rubyinstaller/development-kit).
-
-On Android (with Termux) you can install all requirements by running:
-
-```sh
-apt update && apt install libffi-dev clang ruby-dev make
-```
-
-On macOS, you may need to update RubyGems (using `sudo` only if necessary):
-
-```sh
-gem update --system
-```
-
-If you still have issues, you can download and install new Command Line
-Tools (such as `gcc`) using the following command:
-
-```sh
-xcode-select --install
-```
-
-which may allow you to install native gems using this command (again, using
-`sudo` only if necessary):
-
-```sh
-gem install jekyll
-```
-
-Note that upgrading macOS does not automatically upgrade Xcode itself
-(that can be done separately via the App Store), and having an out-of-date
-Xcode.app can interfere with the command line tools downloaded above. If
-you run into this issue, upgrade Xcode and install the upgraded Command
-Line Tools.
-
-### Running Jekyll as Non-Superuser (no sudo!) 
-{: #no-sudo}
-
-On most flavors of Linux, macOS, and Bash on Ubuntu on Windows, it is
-possible to run Jekyll as a non-superuser and without having to install
-gems to system-wide locations by adding the following lines to the end 
-of your `.bashrc` file:
-
-```
-# Ruby exports
-
-export GEM_HOME=$HOME/gems
-export PATH=$HOME/gems/bin:$PATH
-```
-
-This tells `gem` to place its gems within the user's home folder, 
-not in a system-wide location, and adds the local `jekyll` command to the 
-user's `PATH` ahead of any system-wide paths.
-
-This is also useful for many shared webhosting services, where user accounts
-have only limited privileges. Adding these exports to `.bashrc` before running 
-`gem install jekyll bundler` allows a complete non-`sudo` install of Jekyll.
-
-To activate the new exports, either close and restart Bash, logout and 
-log back into your shell account, or run `. .bashrc` in the 
-currently-running shell.
-
-If you see the following error when running the `jekyll new` command,
-you can solve it by using the above-described procedure:
-
-```sh
-jekyll new test
-
-Running bundle install in /home/user/test...
-
-Your user account isn't allowed to install to the system RubyGems.
-You can cancel this installation and run:
-
-      bundle install --path vendor/bundle
-
-to install the gems into ./vendor/bundle/, or you can enter your password
-and install the bundled gems to RubyGems using sudo.
-
-Password:
-```
-
-Once this is done, the `jekyll new` command should work properly for
-your user account.
-
-### Jekyll & 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
-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:
-
-```
-http://localhost:4000/blog/index.html
-```
-
-It won’t work to just access:
-
-```
-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.
-
-**Note: From v3.3.0 onward, Jekyll does not process `node_modules` and certain subdirectories within `vendor`, by default. But, by having an `exclude:` array defined explicitly in the config file overrides this default setting, which results in some users to encounter an error in building the site, with the following error message:**
-
-```sh
-    ERROR: YOUR SITE COULD NOT BE BUILT:
-    ------------------------------------
-    Invalid date '<%= Time.now.strftime('%Y-%m-%d %H:%M:%S %z') %>':
-    Document 'vendor/bundle/gems/jekyll-3.4.3/lib/site_template/_posts/0000-00-00-welcome-to-jekyll.markdown.erb'
-    does not have a valid date in the YAML front matter.
-```
-
-Simply adding `vendor/bundle` to the `exclude:` list will solve this problem but will lead to having other sub-directories under `/vendor/` (and also `/node_modules/`, if present) be processed to the destination folder `_site`.
-
-
-The proper solution is to incorporate the default setting for `exclude:` rather than override it completely:
-
-For versions upto `v3.4.3`, the `exclude:` setting must look like following:
-
-```yaml
-exclude:
-  - Gemfile
-  - Gemfile.lock
-  - node_modules
-  - vendor/bundle/
-  - vendor/cache/
-  - vendor/gems/
-  - vendor/ruby/
-  - any_additional_item # any user-specific listing goes at the end
-```
-
-From `v3.5` onward, `Gemfile` and `Gemfile.lock` are also excluded by default. So, in most cases there is no need to define another `exclude:` array in the config file. So an existing definition can either be modified as above, or removed completely, or simply commented out to enable easy edits in future.
-
-
-## 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
-
-Liquid 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? A few things have changed in Jekyll 3
-that you'll want to know about.
-
-Before we dive in, go ahead and fetch the latest version of Jekyll:
-
-```sh
-gem update jekyll
-```
-
-Since v3.2 Jekyll requires Ruby version >= 2.1
-{: .note .warning }
-
-<div class="note feature">
-  <h5>Diving in</h5>
-  <p>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`.

-    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.

-
-<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>

-
-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 --livereload
-# LiveReload refreshes your browser after a change.
-
-jekyll serve --incremental
-# Incremental will perform a partial build in order to reduce regeneration time.
-
-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.
-```
-
-```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: 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
-The easiest way to run Jekyll is by using the [RubyInstaller][] for Windows.
-
-### Installation via RubyInstaller
-
-[RubyInstaller][] is a self-contained Windows-based installer that includes the Ruby language, an execution environment, important documentation, and more.
-We only cover RubyInstaller-2.4 and newer here, older versions need to [install the Devkit][Devkit-install] manually.
-
-1. Download and Install a **Ruby+Devkit** version from [RubyInstaller Downloads][RubyInstaller-downloads].
-   Use default options for installation.
-2. Open a new command prompt window from the start menu, so that changes to the `PATH` environment variable becomes effective.
-   Install Jekyll and Bundler via: `gem install jekyll bundler`
-3. Check if Jekyll installed properly: `jekyll -v`
-
-That's it, you're ready to install our [default minimal blog theme](https://github.com/jekyll/minima) with `jekyll new jekyll-website`.
-
-[RubyInstaller]: https://rubyinstaller.org/
-[RubyInstaller-downloads]: https://rubyinstaller.org/downloads/
-[Devkit-install]: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
-
-
-### 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
-
-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', '~> 0.1.1' if Gem.win_platform?
-```
-
-You have to use a [Ruby+Devkit](https://rubyinstaller.org/downloads/) version of the RubyInstaller.
-
-
-## Installation via Bash on Windows 10
-
-If you are using Windows 10 version 1607 or later, another option to run Jekyll is by [installing][WSL-Guide] the Windows Subsystem for Linux.
-
-
-*Note:* You must have [Windows Subsystem for Linux][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:
-
-```sh
-bash
-```
-Your Command Prompt instance should now be a Bash instance. Now we must update our repo lists and packages.
-
-```sh
-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.
-
-```sh
-sudo apt-add-repository ppa:brightbox/ruby-ng
-sudo apt-get update
-sudo apt-get install ruby2.3 ruby2.3-dev build-essential dh-autoreconf
-```
-
-Next let's update our Ruby gems:
-
-```sh
-sudo gem update
-```
-
-Now all that is left to do is install Jekyll.
-
-```sh
-sudo gem install jekyll bundler
-```
-
-Check if Jekyll installed properly by running:
-
-```sh
-jekyll -v
-```
-
-Configure the bundler/gem path so bundle doesn't prompt for sudo
-
-```sh
-bundle config path vendor/bundle
-```
-
-**And that's it!**
-
-To start a new project named `my_blog`, just run:
-
-```sh
-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.
-
-<div class="note info">
-  <h5>Non-superuser account issues</h5>
-  <p>If the `jekyll new` command prints the error "Your user account isn't allowed to install to the system RubyGems", see the "Running Jekyll as Non-Superuser" instructions in <a href="/docs/troubleshooting/#no-sudo">Troubleshooting</a>.</p>
-</div>
-
-**Note:** Bash on Ubuntu on Windows is still under development, so you may run into issues.
