 ## Running tests locally
 
 ### Test Dependencies
 
 To run the test suite and build the gem you'll need to install Jekyll's dependencies by running the following command:
 
-<pre class="highlight"><code>$ script/bootstrap</code></pre>
+```sh
+script/bootstrap
+```
 
 Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
 
-<pre class="highlight"><code>$ script/cibuild</code></pre>
+```sh
+script/cibuild
+```
 
 If you are only updating a file in `test/`, you can use the command:
 
-<pre class="highlight"><code>$ script/test test/blah_test.rb</code></pre>
+```sh
+script/test test/blah_test.rb
+```
 
 If you are only updating a `.feature` file, you can use the command:
 
-<pre class="highlight"><code>$ script/cucumber features/blah.feature</code></pre>
+```sh
+script/cucumber features/blah.feature
+```
 
 Both `script/test` and `script/cucumber` can be run without arguments to
 run its entire respective suite.

+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by opening an issue or contacting a project maintainer. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [https://www.contributor-covenant.org/version/1/4/code-of-conduct.html][version]

+# 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!

+## What is Jekyll, exactly?
 
-Jekyll is a simple, blog-aware, static site generator. It takes a template
-directory containing raw text files in various formats, runs it through
-a converter (like [Markdown](https://daringfireball.net/projects/markdown/))
-and our [Liquid](https://github.com/Shopify/liquid/wiki) renderer, and
-spits out a complete, ready-to-publish static website suitable
-for serving with your favorite web server. Jekyll also happens to be the engine
-behind [GitHub Pages](https://pages.github.com), which means you can use Jekyll
-to host your project’s page, blog, or website from GitHub’s servers **for
-free**.
+Jekyll is a simple, blog-aware, static site generator.
 
-## Helpful Hints
+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.
 
-Throughout this guide there are a number of small-but-handy pieces of
-information that can make using Jekyll easier, more interesting, and less
-hazardous. Here’s what to look out for.

-### Requirements
+- [Requirements](#requirements)
+- [Install Jekyll on macOS](#macOS)
+- [Install Jekyll on Ubuntu Linux](#ubuntu)
+- [Install Jekyll on Windows](../windows/)
+- [Upgrade Jekyll](#upgrade-jekyll)
+
+## Requirements
 
-Installing Jekyll should be straight-forward if all requirements are met.
 Before you start, make sure your system has the following:
 
-- GNU/Linux, Unix, or macOS
-- [Ruby](https://www.ruby-lang.org/en/downloads/) version 2.1 or above, including all development
-  headers
-- [RubyGems](https://rubygems.org/pages/download)
-- [GCC](https://gcc.gnu.org/install/) and [Make](https://www.gnu.org/software/make/) (in case your system doesn't have them installed, which you can check by running `gcc -v` and `make -v` in your system's command line interface)
+- [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)
 
-#### Only required for Jekyll 2 and earlier
+## Install on macOS {#macOS}
 
-- [NodeJS](https://nodejs.org/), or another JavaScript runtime (for CoffeeScript support).
-- [Python 2.7](https://www.python.org/downloads/)
+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).

-## Install with RubyGems
-
-The best way to install Jekyll is via
-[RubyGems](https://rubygems.org/pages/download). At the terminal prompt,
-simply run the following command to install Jekyll:
+First, you need to install the command-line tools to be able to compile native extensions, open a terminal and run:
 
 ```sh
-$ gem install jekyll
+xcode-select --install
 ```
 
-All of Jekyll’s gem dependencies are automatically installed by the above
-command, so you won’t have to worry about them at all.
+### 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.

-  <h5>Installing Xcode Command-Line Tools</h5>
-  <p>
-    If you run into issues installing Jekyll's dependencies which make use of
-    native extensions and are using macOS, you will need to install Xcode
-    and the Command-Line Tools it ships with. Download them in
-    <code>Preferences &#8594; Downloads &#8594; Components</code>.
-  </p>
 </div>
 
+## 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.

+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!

 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:
 
-```

 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.

+## 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 as the `post.excerpt`.
+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:
 
-```html
+{% raw %}
+```liquid
 <ul>
-  {% raw %}{% for post in site.posts %}{% endraw %}
+  {% for post in site.posts %}
     <li>
-      <a href="{% raw %}{{ post.url }}{% endraw %}">{% raw %}{{ post.title }}{% endraw %}</a>
-      {% raw %}{{ post.excerpt }}{% endraw %}
+      <a href="{{ post.url }}">{{ post.title }}</a>
+      {{ post.excerpt }}
     </li>
-  {% raw %}{% endfor %}{% endraw %}
+  {% 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:
 
-```html
-{% raw %}{{ post.excerpt | remove: '<p>' | remove: '</p>' }}{% endraw %}
+{% 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:

 * `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.

+### 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.
+

+```
+
+Once this is done, the `jekyll new` command should work properly for

-in `_config.yml`.
+**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') %>':

+    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.

+### Template rendering
+
+We've slightly altered the way Jekyll parses and renders your various templates to improve
+the overall build times. Jekyll now parses a template once, caches it internally and then
+renders the parsed template multiple times as required by your pages and documents.
+
+The downside to this is that some of the community-authored plugins may not work as they
+previously used to.
+
+#### For Plugin-authors
+
+* If your plugin depends on the following code: `site.liquid_renderer.file(path).parse(content)`,
+note that the return value (`template`, an instance of *`Liquid::Template`*), from that line will
+always be the **same object** for a given `path`. <br/>
+The *`template`* instance is then rendered as previously, with respect to the `payload` passed to it.
+You'll therefore have to ensure that *`payload`* is not memoized or cached in your plugin instance.
+
+* If its a requirement that `template` you get from the above step *be different* at all times,
+you can invoke *`Liquid::Template`* directly:
+
+
+  ```diff
+  - template = site.liquid_renderer.file(path).parse(content)
+  + template = Liquid::Template.parse(content)
+  ```

-
-To start a new project named `my_blog`, just run:

-### Installing *github-pages* via Chocolatey
-
-This section is part of an article written by [Jens Willmer][jwillmerPost]. To follow the instructions you need to have [Chocolatey][] installed on your system. If you already have a version of Ruby installed you need to uninstall it before you can continue.
-
-
-#### Install Ruby and Ruby development kit
-
-Open a command prompt and execute the following commands:
-
- * `choco install ruby -version 2.2.4`
- * `choco install ruby2.devkit` - _needed for compilation of json gem_
-
-
-#### Configure Ruby development kit
-
-The development kit did not set the environment path for Ruby so we need to do it.
-
- * Open command prompt in `C:\tools\DevKit2`
- * Execute `ruby dk.rb init` to create a file called `config.yml`
- * Edit the `config.yml` file and include the path to Ruby `- C:/tools/ruby22`
- * Execute the following command to set the path: `ruby dk.rb install`
-
-
-#### Nokogiri gem installation
-
-This gem is also needed in the github-pages and to get it running on Windows x64 we have to install a few things.
-
-**Note:** In the current [pre release][nokogiriFails] it works out of the box with Windows x64 but this version is not referenced in the github-pages.
-
-`choco install libxml2 -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
-
-`choco install libxslt -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
-
-`choco install libiconv -Source "https://www.nuget.org/api/v2/"`{:.language-ruby}
-
-```ruby
- gem install nokogiri --^
-   --with-xml2-include=C:\Chocolatey\lib\libxml2.2.7.8.7\build\native\include^
-   --with-xml2-lib=C:\Chocolatey\lib\libxml2.redist.2.7.8.7\build\native\bin\v110\x64\Release\dynamic\cdecl^
-   --with-iconv-include=C:\Chocolatey\lib\libiconv.1.14.0.11\build\native\include^
-   --with-iconv-lib=C:\Chocolatey\lib\libiconv.redist.1.14.0.11\build\native\bin\v110\x64\Release\dynamic\cdecl^
-   --with-xslt-include=C:\Chocolatey\lib\libxslt.1.1.28.0\build\native\include^
-   --with-xslt-lib=C:\Chocolatey\lib\libxslt.redist.1.1.28.0\build\native\bin\v110\x64\Release\dynamic
-```
-
-#### Install github-pages 
-
-  * Open command prompt and install [Bundler][]: `gem install bundler`
-  * Create a file called `Gemfile` without any extension in your root directory of your blog
-  * Copy & paste the two lines into the file:
-
-
-```ruby
-source 'https://rubygems.org'
-gem 'github-pages', group: :jekyll_plugins
-```
-
- * **Note:** We use an unsecure connection because SSL throws exceptions in the version of Ruby
- * Open a command prompt, target your local blog repository root, and install github-pages: `bundle install`
-
-
-After this process you should have github-pages installed on your system and you can host your blog again with `jekyll s`.
-There will be a warning on startup that you should include `gem 'wdm', '>= 0.1.0' if Gem.win_platform?` to your `Gemfile` but I could not get `jekyll s` working if I include that line so for the moment I ignore that warning.
-
-In the future the installation process of the github-pages should be as simple as the setup of the blog. But as long as the new version of the Nokogiri ([v1.6.8][nokogiriReleases]) is not stable and referenced, it is work to get it up and running on Windows.

+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 ruby2.4 ruby2.4-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.

 - Speaking of themes, we'll properly handle the discrepancy between a convertible file in the local site and a static file in the theme. Overriding a file locally now doesn't matter if it's convertible or static.
 - Pages, posts, and other documents can now access layout variables via `{% raw %}{{ layout }}{% endraw %}`.

+Another much-anticipated release of Jekyll. This release comes with it Rouge 2 support, but note you can continue to use Rouge 1 if you'd prefer. We also now require Ruby 2.1.0 as 2.0.x is no longer supported by the Ruby team.
+
+Otherwise, it's a massive bug-fix release! A few bugs were found and squashed with our `Drop` implementation. We're using the Schwartzian transform to speed up our custom sorting (thanks, Perl community!). We now protect against images that are named like posts and we generally worked on guarding our code to enforce requirements, instead of assuming the input was as expected.
+
+Please let us know if you find any bugs! You can see [the full history here](/docs/history/#v3-6-0).
+
+Many thanks to our contributors who helped make this release possible: Aleksander Kuś, André Jaenisch, Antonio Argote, ashmaroli, Ben Balter, Bogdan, Bradley Meck, David Zhang, Florian Thomas, Frank Taillandier, Jordon Bedwell, Joshua Byrd, Kyle Zhao, lymaconsulting, Maciej Bembenista, Matt Sturgeon, Natanael Arndt, Ohad Schneider, Pat Hawks, Pedro Lamas, and Sid Verma.
+
+As always, Happy Jekylling!

+title: "Diversity in Open Source, and Jekyll's role in it"
+date: 2017-10-19 21:33:00 +0200
+author: oe
+categories: [community]
+---
+
+Open Source has a problem with diversity. GitHub recently conducted a [survey](http://opensourcesurvey.org/2017) which revealed that 95% of the respondents were identifying as male. This is even worse than in the tech industry overall, where the percentage is only about 76%. Every other week, there seems to be another case of a maintainer engaging in targeted harassment against minorities. People somehow deem it completely okay to let these things slide, though.
+
+Fortunately, there's a couple of things we can do to make it easier and more comfortable for people that have never contributed to any open source project before, to contribute to our projects.
+
+## Add a Code of Conduct, and enforce it
+
+This might seem like one of the easiest steps to do, but it actually requires a lot of dedication to pull through with. Basically, a Code of Conduct is a document detailing what is and what isn't acceptable behavior in your project. A good Code of Conduct also details enforcement procedures, that means how the person violating the Code of Conduct gets dealt with. This is the point at which I've seen a looooot of projects fail. It's easy enough to copy-paste a Code of Conduct into your project, but it's more important to be clear on how to enforce it. Inconsistent —or worse, nonexistent— enforcement is just going to scare off newcomers even more!
+
+The most widely adopted Code of Conduct is the [Contributor Covenant](https://www.contributor-covenant.org/). It's a very good catch-all document, but it is a bit light in the enforcement section, so I'd recommend to flesh it out by yourself, be it by means of adding contact information or expanding the enforcement rules.
+
+No matter which Code of Conduct you pick, the most important thing is to actually _read it for yourself_. The worst thing in open source is a maintainer that doesn't know when they've violated their own Code of Conduct.
+
+## Document your contributing workflow
+
+The problem that puts people off the most is incomplete or missing documentation, as revealed through GitHub's [open source survey](http://opensourcesurvey.org/2017). A very popular myth in programming is that good code explains itself, which might be true, but only for the person writing it. It's important, especially once you put your project out there for the world to see, to document not only your code, but also the process by which you maintain it. Otherwise, it's going to be extremely hard for newcomers to even figure out where to begin contributing to your project.
+
+Jekyll has [an entire section of its docs](/docs/contributing) dedicated to information on how to contribute for this very reason. Every documentation page has a link to directly edit and improve it on GitHub. It's also important to realize that not all contributions are code. It can be documentation, it can be reviewing pull requests, but it can also just be weighing into issues, and all of this should be recognized in the same way. At Jekyll, out of 397 total merged pull requests in the last year, __204__ were documentation pull requests!
+
+## Create newcomer-friendly issues
+
+For most people new to open source, the biggest hurdle is creating their first pull request. That's why initiatives such as [YourFirstPR](https://twitter.com/yourfirstpr) and [First Timers Only](http://www.firsttimersonly.com/) were started. Recently, [a GitHub bot that automatically creates first-timer friendly issues](https://github.com/hoodiehq/first-timers-bot) was launched, which makes it very easy for maintainers to convert otherwise small or trivial changes into viable pull requests that can be taken on by newcomers! So we decided to give it a shot, and we've created a couple of very easy `first timers only` issues:
+
+- [Issue #6437](https://github.com/jekyll/jekyll/issues/6437)
+- [Issue #6438](https://github.com/jekyll/jekyll/issues/6438)
+- [Issue #6439](https://github.com/jekyll/jekyll/issues/6439)
+
+(There's also an up-to-date listing of all of our `first timers only` issues [here](https://github.com/jekyll/jekyll/issues?q=is%3Aissue+is%3Aopen+label%3Afirst-time-only))
+
+These issues are designed to be taken on only by someone who has had little to no exposure to contributing to open source before, and additionally, project maintainers offer support in case a question arises.
+
+Jekyll is a very big and popular open source project, and we hope that with these special issues, we can help people who haven't contributed to open source before to catch a footing in these unsteady waters.
+
+## Be nice
+
+I know this is a cliche and a overused phrase, but really, it works if you pull through with it. Come to terms with the fact that some people aren't as fast or reliable as you might want to think. Don't get angry when a contributor takes a day longer than you might like them to. Treat new contributors to your project with respect, but also with hospitality. Think twice before you send that comment with slurs in it.
+
+I've been contributing to open source for about 4 years now, and I've had my fair share of horrible, horrible experiences. But Jekyll has historically been a project that has always valued the people contributing to it over the code itself, and I hope we can keep it that way. I also hope that other project maintainers read this and take inspiration from this post. Every project should be more diverse.

+
+3.6.2 is out, it's a tiny patch release and we invite you to run `bundle update`
+if you want to avoid possible build problems with:
+
+* some UTF-8 and UTF-16 encoded files,
+* fully numeric layout names (we convert those to string for you now).
+
+Other changes include updates to our documentation, like this [complete
+video series by Giraffe Academy](../tutorials/video-walkthroughs/) aimed at

+
+And if you're wondering what happened to version 3.6.1, it was just our new
+release maintainer getting familiar with the release process. 😄
+
+We try to release patch releases as quickly as possible and we're already
+working on the next minor version 3.7.0 that will allow you to store all your
+collections in a single directory. Stay tuned.
+
+Theme developers are invited to test the brand new
+[`jekyll-remote-theme`](https://github.com/benbalter/jekyll-remote-theme) plugin
+and give their feedback to @benbalter. This plugin allows you to use any
+GitHub hosted theme as a remote theme!

+We're happy to release a new minor for the new year.
+Here are a few of the latest additions from our contributors:
+
+ * LiveReload is available as an option during development: with `jekyll serve --livereload` no more manual page refresh. A big thanks to @awood for this feature and to @andreyvit, LiveReload author.
+ * New `collections_dir` configuration option allows you to store all your [collections](/docs/collections) in a single folder. Your source root folder should now look cleaner :sparkles: .
+ * If you're using a [gem-based theme](/docs/themes/) in coordination with the `--incremental` option, you should notice some significant speed during the regeneration process, we did see build time went down **from 12s to 2s** with @mmistakes [minimal-mistakes theme](https://github.com/mmistakes/minimal-mistakes) during our tests.
+ * Jekyll will now check to determine whether host machine has internet connection.
+ * A new `latin` option is available to better [handle URLs slugs](/docs/templates/#options-for-the-slugify-filter).
+ * And of course many bug fixes and updates to our documentation — which you can now search thanks to our friends @Algolia.

+
+### :pray: upgrade your Ruby
+
+Prepare for the next major update, as next major version Jekyll 4.0 will drop support for Ruby 2.1 and 2.2.
+
+> Ruby 2.2 is now under the state of the security maintenance phase, until the end of the March of 2018. After the date, maintenance of Ruby 2.2 will be ended. We recommend you start planning migration to newer versions of Ruby, such as 2.4 or 2.3. — [Ruby Core Team](https://www.ruby-lang.org/en/news/2017/12/14/ruby-2-2-9-released/)
+
+We strongly encourage you to upgrade to at least Ruby 2.4.x [like our friends at GitHub Pages](https://pages.github.com/versions/) or even go with [Ruby 2.5](https://www.ruby-lang.org/en/news/2017/12/25/ruby-2-5-0-released/).

+title: "Jekyll 3.7.2 Released"
+date: 2018-01-25 22:22:22 +0530
+author: ashmaroli
+version: 3.7.2
+categories: [release]
+---
+
+Close on the heels of shipping 3.7.0, we were informed of a couple of
+regressions due to the changes made in that release. In due time, Team Jekyll
+set out to address those issues as early as possible.
+
+Days later here we're, announcing 3.7.2 (sorry for skipping 3.7.1, 
+RubyGems didn't want to play nice) that fixes numerous issues! :tada:
+The highlights being:
+
+  * A major regression in 3.7.0 was that when a Front Matter Default was
+    configured with a `scope["path"]` set to a directory, Jekyll would scan
+    that directory for any subfolders and files, for each document in that
+    `path`.
+    Though this is intended, it increases build times in proportion to the size
+    of the directory.
+
+    We addressed this by having Jekyll scan the directory path only if the user
+    explicitly configures the `scope["path"]` using wildcards.
+
+    Read our [documentation](/docs/configuration/#glob-patterns-in-front-matter-defaults)
+    for more details.
+
+    A huge shout-out to @mmistakes for bringing this to our notice and
+    additionally providing us with a test repository to aid in resolving the issue.
+
+  * Another regression reported was related to our "Custom collections
+    directory" feature introduced in 3.7.0.
+
+    Users setting `collection_dir` to a certain directory would have *altered*
+    paths to their posts still at the root of their site's source. This
+    roughly translated to 404 errors on URLs to their posts.
+
+    Props to @localheinz for bringing this regression to our notice.
+
+    We decided to resolve this by having Jekyll ignore posts and drafts at the
+    root of the site's source directory if the user customizes the
+    `collection_dir` setting.
+
+    Ergo, if you set a custom location for your collections, please ensure you
+    move all of your collections into that directory. **This includes posts and
+    drafts as well**. Your links generated by
+    `{% raw %}{% post_url %}{% endraw %}` or `{% raw %}{% link %}{% endraw %}`
+    will adapt automatically.
+
+  * We also found out that `gem "wdm"` boosts performance while directories are
+    being watched on Windows. So we recommend having it included in your Gemfile
+    for a better development experience on Windows. (Newly generated Gemfiles
+    will hereafter have that gem listed automatically :wink:)
+
+In addition to the above, numerous other minor fixes and documentation updates
+have been made that should improve your Jekyll experience. All of which, would
+not have been possible without our wonderful contributors:
+
+Alexandr, Andreas Möller, Ashwin Maroli, Chayoung You, Florian Thomas,
+Frank Taillandier, Hendrik Schneider, Kacper Duras, Olivia, Parker Moore and
+Paul Robert Lloyd.
+
+As always, you can see our full changelog on [the History page](/docs/history/).

+
+Jekyll has a new Lead Developer: [Olivia](https://liv.cat/)!
+
+After over 5 years of leading Jekyll, many releases from 0.12.1 to 3.6.0, and
+countless conversations in GitHub Issues, Pull Requests, Jekyll Talk, and
+more, I am passing on the torch as Lead Developer of Jekyll.
+
+Olivia has been working with the Jekyll community for some time now. You
+may have seen her around in issues and pull requests on the various Jekyll
+repositories. She started as a contributor, then joined the Core team as our
+community lead. Olivia joined the Jekyll Core Team with experience in the
+Node.js community, both online and as a volunteer organizer with JSConf EU.
+
+In my conversations with Olivia, it is clear that Jekyll's vision of
+simplicity for the user ([no magic!](/philosophy#1-no-magic)) and letting
+users' [content be king](/philosophy#3-content-is-king) will remain a top
+priority. In just the last few weeks as the transition has been occurring,
+we have seen some incredible work on performance that will make future
+versions of Jekyll work better at scale. She will be prioritizing work on
+innovative improvements to make Jekyll that much better for all of us.
+Olivia balances an eye for quality with the need for shipping well.
+
+When Tom Preston-Werner met me at GitHub HQ 2.0 in January 2013 to pass on
+the torch, I could never have dreamed of all the amazing experiences this
+community would share with me over the next 5 years. From visiting @qrush
+in Buffalo, NY for a hack night on Jekyll to attending a Jekyll planning
+session hosted by @benbalter at GitHub to Google Summer of Code which gave
+us jekyll-admin, I am eternally grateful to all of you for the opportunity
+to lead this excellent community. I'm confident Olivia will continue to
+lead Jekyll to even greater heights.
+
+As always, Happy Jekylling!

+
+Hello Jekyllers!! :wave:
+
+We're pleased to announce the release of `v3.7.3` which fixes a bug one might encounter while using `Jekyll - 3.7.x` along with a
+Jekyll plugin that in turn uses the `I18n` library.
+
+When [v3.7.0]({% link _posts/2018-01-02-jekyll-3-7-0-released.md %}) enhanced our `slugify` filter with a `latin` option, we also
+hardcoded a default fallback locale for the `I18n` library to avoid an exception raised in the event the library fails to find
+any locale. This led to issues with third-party i18n plugins for Jekyll, especially since the default locale got assigned before
+the plugin was loaded, irrespective of whether the `slugify` filter was used.
+
+Jekyll will henceforth set the default locale if and only if necessary.

+
+With the release of Jekyll 3.8.0, it's been 2 and a half years since the last major release. Jekyll 3.0.0 was released in late October of 2015! That's a long time ago, and we've been working towards the next major release of Jekyll for a couple of months now. Here's a small preview of what's to come:
+
+- Dropping support for Ruby 2.1 and 2.2. Both versions have reached their EOL period.
+- Dropping Pygments as a dependency. We're already defaulting to Rouge, and this removes the implicit Python dependency. (finally!)
+- Making the `link` tag use relative URLs. This is a big breaking change, but it's the cleaner solution.
+
+We're open to more ideas, though. If the development cost isn't too high, or if someone volunteers to take care of the implementation, it's likely that your suggestion might make it into Jekyll 4.0. Head over to this [issue] for more details. Some interesting topics might be improving Internationalization support in Jekyll, creating convenience Liquid tags, et cetera.
+
+That being said, the development period of version 4.0 begins _now_. This means a couple of things:
+
+- New features will only be implemented in Jekyll 4.0. There will be no 3.9.0 or the like.
+- Same with bug fixes, unless they concern something introduced in Jekyll 3.7 or 3.8, in which case we will backport the fixes and release a patch version.
+- Now is a great time to finally take on the feature you've wanted to see in Jekyll for ages! Just open an issue or experiment with the code to get going!
+
+As for a release date, we're currently aiming for late summer, around September or so. However, keep in mind that this project is purely volunteer-run, and as such, delays might occur and we might not hit that release date.
+
+Finally, this is a great time for newcomers to open-source to make their first contribution. We'll be doing our best to mark recommended contributions and create newcomer-friendly issues, as well as to provide mentoring throughout the contribution process (although we'd like to think that we're already pretty proficient at that). So if you've always been hestitant about contributing to a large open-source project, Jekyll is a good place to start!
+
+Happy Jekylling! :wave:

+
+After months of toiling on the codebase and shipping a couple of release-candidates, the Jekyll Team is delighted to finally
+present `v3.8.0`, packed with optimizations, improvements, some new features and a couple of bug-fixes. Yay!!!
+
+Under the hood, Jekyll has undergone many minor changes that will allow it to run more performantly in the coming years. :smiley:
+Rest assured, our users should see minor improvements in their site's build times.
+
+Speaking of improvements, users running a site containing a huge amount of posts or those who like to use our `where` filter
+frequently in a single template, are going to see a massive reduction in their total build times!! :tada:
+
+Hold on, this version is not just about optimizations, there are some new features as well..:
+  * Detect non-existent variables and filters specified in a template by enabling `strict_variables` and `strict_filters` under the
+  `liquid` key in your config file.
+  * Allow *date filters* to output ordinal days.
+  * `jekyll doctor` now warns you if you have opted for custom `collections_dir` but placed `_posts` directory outside that
+  directory.
+
+..and yes, a couple of bug-fixes, notably:
+  * Jekyll now handles future-dated documents properly.
+  * Jekyll is able to handle Liquid blocks intelligently in excerpts.
+  * A few methods that were *not meant to be publically accessible* have been entombed properly.
+  * A few bugs that still plagued our `collections_dir` feature from `v3.7` got crushed.
+
+As always, the full list of changes since last release can be viewed [here](/docs/history/#v3-8-0).

+_(TL;DR: We're open for sponsorships on our [OpenCollective page](https://opencollective.com/jekyll))_
+
+Hi Jekyllers,
+
+As you may know, Jekyll is a completely free and open source project. We offer our
+software and its related plugins and documentation at no cost because we believe
+that good software should not cost anything. We're not planning on changing that,
+but today I want to talk about a different monetary aspect of open source.
+
+Open source developers being paid for the work they do is a rare sight. Most open source
+software is effectively the result of hundreds and thousands of hours of free labor provided
+by individuals who are passionate enough to work outside of their day job to create
+software that, ironically, is being used by almost every company that offers
+digital services. It's a problem that has gotten more attention in recent years, with
+the open source community becoming more diverse and more and more companies actively
+investing in providing monetary support for open source developers.
+
+Jekyll has always been a product of volunteers. Rarely has someone been paid to implement
+a certain plugin or feature. Today, we're excited to announce that we will finally
+be able to fund our contributors! __We are opening an OpenCollective to receive
+individual and corporate sponsorships__. This is not unheard of, [Hugo](http://gohugo.io)
+is also funded by sponsorships, as are many other similar projects, such as
+[webpack](https://opencollective.com/webpack), [Babel](https://opencollective.com/babel) or
+[RuboCop](https://opencollective.com/rubocop).
+
+OpenCollective is a service that makes it easy for open source projects to receive funding
+from individuals and companies alike. It's specifically designed for open source and
+many other projects already use it for funding.
+
+Sponsoring is, for us, a method to finally realize some of the more ambitious goals we've had
+with the project for years. The closest thing we want to realize is to __release Jekyll 4.0, and
+to make it as polished as we can__. In the future, we would also like to work on other things that
+will improve the Jekyll ecosystem. Here's a couple of ideas:
+
+- Create a comprehensive official plugin and theme directory site
+- Improve tooling built around measuring and improving Jekyll's performance
+- Improve maintenance for official plugins
+- Including the community into official decisions; making Jekyll more friendly to folks in the community
+
+Again, these are just some ideas, but with the help of sponsoring, they are now one step closer
+to being realized :heart:
+
+<div align="center">
+  <img src="/img/forestry-logo.png" width="300" />
+</div>
+
+With that, we would like to announce our very first sponsor: [__Forestry.io__](https://forestry.io)! Forestry is
+a CMS that integrates with your Jekyll sites and lets you update content using a beautiful
+interface, and then automatically commits it back to your GitHub repository. We're excited to have
+them on board on a new, exciting step of our journey.
+
+Will anything change for Jekyll users? The answer is no - this step does not impact the Jekyll software
+in any aspect. In fact, you might see positive changes, such as more features and better
+performance. Surprisingly, that's what happens when you properly fund people for their work!
+
+If you have been a long time user for Jekyll and would like to give something back to the project,
+you can consider a small monthly donation to our [OpenCollective page](http://opencollective.com/jekyll).
+If your company heavily relies on Jekyll, do consider sponsoring us! Contact me at
+`olivia at fastmail dot com` and we'll figure something out together.
+
+Thanks for sticking with us, and happy Jekylling! :tada:
