+# Contributing to Jekyll
+
+Hi there! Interested in contributing to Jekyll? We'd love your help. Jekyll is an open source project, built one contribution at a time by users like you.
+
+## Where to get help or report a problem
+
+* If you have a question about using Jekyll, start a discussion on [Jekyll Talk](https://talk.jekyllrb.com).
+* If you think you've found a bug within a Jekyll plugin, open an issue in that plugin's repository.
+* If you think you've found a bug within Jekyll itself, [open an issue](https://github.com/jekyll/jekyll/issues/new)
+* More resources are listed on our [Help page](https://jekyllrb.com/help/)
+
+## Ways to contribute
+
+Whether you're a developer, a designer, or just a Jekyll devotee, there are lots of ways to contribute. Here's a few ideas:
+
+* [Install Jekyll on your computer](https://jekyllrb.com/docs/installation/) and kick the tires. Does it work? Does it do what you'd expect? If not, [open an issue](https://github.com/jekyll/jekyll/issues/new) and let us know.
+* Comment on some of the project's [open issues](https://github.com/jekyll/jekyll/issues). Have you experienced the same problem? Know a work around? Do you have a suggestion for how the feature could be better?
+* Read through [the documentation](https://jekyllrb.com/docs/home/), and click the "improve this page" button, any time you see something confusing, or have a suggestion for something that could be improved.
+* Browse through [the Jekyll discussion forum](https://talk.jekyllrb.com/), and lend a hand answering questions. There's a good chance you've already experienced what another user is experiencing.
+* Find [an open issue](https://github.com/jekyll/jekyll/issues) (especially [those labeled `help-wanted`](https://github.com/jekyll/jekyll/issues?q=is%3Aopen+is%3Aissue+label%3Ahelp-wanted)), and submit a proposed fix. If it's your first pull request, we promise we won't bite, and are glad to answer any questions.
+* Help evaluate [open pull requests](https://github.com/jekyll/jekyll/pulls), by testing the changes locally and reviewing what's proposed.
+
+## Submitting a pull request
+
+### Pull requests generally
+
+* The smaller the proposed change, the better. If you'd like to propose two unrelated changes, submit two pull requests.
+
+* The more information, the better. Make judicious use of the pull request body. Describe what changes were made, why you made them, and what impact they will have for users.
+
+* Pull request 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 lcoally `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 [site](https://github.com/jekyll/jekyll/tree/master/site) 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).
+
+### 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](site/_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 `site/_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 if more than enough. You can usually copy/paste from an existing example in the `tests` folder, but if you need to 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 follows the [GitHub Ruby Styleguide](https://github.com/styleguide/ruby).
+
+* Don't bump the Gem version in your pull request (if you don't know what that means, you probably didn't).
+
+## Running tests locally
+
+### Test Dependencies
+
+To run the test suite and build the gem you'll need to install Jekyll's dependencies by running the following command:
+
+    $ script/bootstrap
+
+Before you make any changes, run the tests and make sure that they pass (to confirm your environment is configured properly):
+
+    $ script/cibuild
+
+If you are only updating a file in `test/`, you can use the command:
+
+    $ script/test test/blah_test.rb
+
+If you are only updating a `.feature` file, you can use the command:
+
+    $ 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!

-Contribute
-==========
-
-So you've got an awesome idea to throw into Jekyll. Great! Please keep the
-following in mind:
-
-* **Use https://talk.jekyllrb.com for non-technical or indirect Jekyll questions that are not bugs.**
-* **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
-  [RSpec-Mocks](https://github.com/rspec/rspec-mocks).
-* 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!

-Jekyll is a simple, blog-aware, static site generator perfect for personal, project, or organization sites. Think of it like a file-based CMS, without all the complexity. Jekyll takes your content, renders Markdown and Liquid templates, and spits out a complete, static website ready to be served by Apache, Nginx or another web server. Jekyll is the engine behind [GitHub Pages](http://pages.github.com), which you can use to host sites right from your GitHub repositories.

 ## Philosophy
 
 Jekyll does what you tell it to do — no more, no less. It doesn't try to outsmart users by making bold assumptions, nor does it burden them with needless complexity and configuration. Put simply, Jekyll gets out of your way and allows you to concentrate on what truly matters: your content.
