docs: update wsl installation procedure (#9968)

This is a 🔦 documentation change.

## Summary

The install documentation for WSL offers to install Ruby through
BrightBox. However, BrightBox does not support Ubuntu Jammy (which is
the default for latest WSL builds). Instead, this commit just redirects
the WSL user to the Ubuntu installation procedure to avoid duplicate
documentation.

+# 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, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, 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 contacting the project team at [olivia@jekyllrb.com](mailto:olivia@jekyllrb.com). All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and 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](https://www.contributor-covenant.org/version/1/4/code-of-conduct.html)

+# 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 workaround? 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.
+
+- 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
+
+Interested 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)
+
+- Previously, we've used the WIP Probot app to help contributors determine whether their pull request is ready for review. Please use a [draft pull request](https://help.github.com/en/articles/about-pull-requests#draft-pull-requests) instead. When you're ready, [mark the pull request as ready for review](https://help.github.com/en/articles/changing-the-stage-of-a-pull-request)
+
+## 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.
+
+## Visual Studio Code Development Container
+
+If you've got [Visual Studio Code](https://code.visualstudio.com/) with the [Remote Development Extension Pack](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack) installed then simply opening this repository in Visual Studio Code and following the prompts to "Re-open In A Development Container" will get you setup and ready to go with a fresh environment with all the requirements installed.
+
+## 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 feature request with Jekyll. Please take the time to
+  answer the basic questions. Please try to be as detailed as possible.
+
+  Thanks!
+-->
+
+## Summary
+
+<!--
+  A one-paragraph explanation of the feature.
+-->
+
+## Motivation
+
+<!--
+  Why do you want to see this feature in Jekyll? What makes you sure that it should not be
+  implemented at the plugin level, but in Jekyll core? What use cases does it support?
+
+  NOTE: Please be mindful of the Jekyll philosophy (https://jekyllrb.com/philosophy/),
+  particularly Section 5. Think about if 90% of the users would benefit from your
+  feature request, and whether your feature would be better off in a plugin.
+-->
+
+## Guide-level explanation
+
+<!--
+  Explain the proposal as if it was already included in the project and you
+  were teaching it to another programmer. That generally means:
+
+  - Introducing new named concepts.
+  - Explaining the feature largely in terms of examples.
+  - If applicable, provide sample error messages, deprecation warnings, or
+    migration guidance.
+
+  If this is a small feature, you may omit this section.
+-->
+
+## Reference-level explanation
+
+<!--
+  This is the technical portion of the feature request. Explain the design in
+  sufficient detail that:
+
+  - Its interaction with other features is clear.
+  - It is reasonably clear how the feature would be implemented.
+  - Corner cases are dissected by example.
+
+  If you do not know how to answer this, you can omit it. No worries!
+-->
+
+## Drawbacks
+
+<!--
+  Why should we *not* do this?

+
+## Unresolved Questions

+# Jekyll Support
+
+## Getting Help
+
+**Jekyll's issue tracker is not a support forum.**
+
+If you're looking for support for Jekyll, there are a lot of options:
+
+* Read [Jekyll Documentation](https://jekyllrb.com/docs/home/)
+* If you have a question about using Jekyll, start a discussion on [Jekyll Forum](https://talk.jekyllrb.com/) or [StackOverflow](https://stackoverflow.com/questions/tagged/jekyll)
+* Chat with Jekyllers — Join [our Gitter channel](https://gitter.im/jekyll/jekyll) or [our IRC channel on Freenode](irc:irc.freenode.net/jekyll)
+
+There are a bunch of helpful community members on these services that should be willing to point you in the right direction.
+
+## Report a bug
+
+* If you think you've found a bug within a Jekyll plugin, open an issue in that plugin's repository — First [look for the plugin on rubygems](https://rubygems.org/) then click on the `Homepage` link to access the plugin repository.
+* If you think you've found a bug within Jekyll itself, [open an issue](https://github.com/jekyll/jekyll/issues/new).
+
+Happy Jekyllin'!

-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. Simply run this command to get all setup:
-
-    $ script/bootstrap
-
-Before you start, 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.
-
-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 `script/cibuild`.
-* 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.
-
-If you want to add your plugin to the
-[list of plugins](http://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.
-
-Gotchas
--------
-
-* Please do not bump the gem version in your pull requests.
-* 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.

+# 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!

+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, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, 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

+title: Collections
+permalink: /docs/collections/
+---
+
+Collections are a great way to group related content like members of a team or
+talks at a conference.
+
+## Setup
+
+To use a Collection you first need to define it in your `_config.yml`. For
+example here's a collection of staff members:
+
+```yaml
+collections:
+  - staff_members
+```
+
+In this case `collections` is defined as a sequence (i.e., array) with no additional metadata defined for each collection.
+You can optionally specify metadata for your collection by defining `collections` as a mapping (i.e., hashmap) instead of sequence, and then defining additional fields in it:
+
+```yaml
+collections:
+  staff_members:
+    people: true
+```
+
+{: .note .info}
+When defining a collection as a sequence, its pages will not be rendered by
+default. To enable this, <code>output: true</code> must be specified on the
+collection, which requires defining the collection as a mapping. For more
+information, see the section <a href="#output">Output</a>.
+
+<div class="note">
+  <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 drafts and 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>_drafts</code> and <code>_posts</code> directory to <code>my_collections/_drafts</code> and <code>my_collections/_posts</code>. Note that, the name of your collections directory cannot start with an underscore (`_`).</p>
+</div>
+
+## Add content
+
+Create a corresponding folder (e.g. `<source>/_staff_members`) and add
+documents. 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 front
+matter is provided, Jekyll will consider it to be a [static file]({{ '/docs/static-files/' | relative_url }})
+and the contents will not undergo further processing. If front matter is provided,
+Jekyll will process the file contents into the expected output.
+
+Regardless of whether front matter exists or not, Jekyll will write to the destination
+directory (e.g. `_site`) only if `output: true` has been set in the collection's
+metadata.
+
+For example here's how you would add a staff member to the collection set above.
+The filename is `./_staff_members/jane.md` with the following content:
+
+```markdown
+---
+name: Jane Doe
+position: Developer
+---
+Jane has worked on Jekyll for the past *five years*.
+```
+
+<em>
+  Do note that in spite of being considered as a collection internally, the above
+  doesn't apply to [posts](/docs/posts/). Posts with a valid filename format will be
+  marked for processing even if they do not contain front matter.
+</em>
+
+<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>
+
+## Output
+
+Now you can iterate over `site.staff_members` on a page and output the content
+for each staff member. Similar to posts, the body of the document is accessed
+using the `content` variable:
+
+{% raw %}
+```liquid
+{% for staff_member in site.staff_members %}
+  <h2>{{ staff_member.name }} - {{ staff_member.position }}</h2>
+  <p>{{ staff_member.content | markdownify }}</p>
+{% endfor %}
+```
+{% endraw %}
+
+If you'd like Jekyll to create a rendered page for each document in your
+collection, you can set the `output` key to `true` in your collection
+metadata in `_config.yml`:
+
+```yaml
+collections:
+  staff_members:
+    output: true
+```
+
+You can link to the generated page using the `url` attribute:
+
+{% raw %}
+```liquid
+{% for staff_member in site.staff_members %}
+  <h2>
+    <a href="{{ staff_member.url }}">
+      {{ staff_member.name }} - {{ staff_member.position }}
+    </a>
+  </h2>
+  <p>{{ staff_member.content | markdownify }}</p>
+{% endfor %}
+```
+{% endraw %}
+
+## Future
+
+You can configure a collection to show future items by setting the `future` metadata to `true` in the collection's configuration.
+
+```yaml
+collections:
+  staff_members:
+    future: true
+```
+
+## Permalinks
+
+There are special [permalink variables for collections]({{ '/docs/permalinks/#collections' | relative_url }}) to
+help you control the output url for the entire collection.
+
+## Custom Sorting of Documents {%- include docs_version_badge.html version="4.0" -%}
+{: #custom-sorting-of-documents}
+
+By default, two documents in a collection are sorted by their `date` attribute when both of them have the `date` key in their front matter. However, if either or both documents do not have the `date` key in their front matter, they are sorted by their respective paths.
+
+You can control this sorting via the collection's metadata.
+
+### Sort By Front Matter Key
+
+Documents can be sorted based on a front matter key by setting a `sort_by` metadata to the front matter key string. For example,
+to sort a collection of tutorials based on key `lesson`, the configuration would be:
+
+```yaml
+collections:
+  tutorials:
+    sort_by: lesson
+```
+
+The documents are arranged in the increasing order of the key's value. If a document does not have the front matter key defined
+then that document is placed immediately after sorted documents. When multiple documents do not have the front matter key defined,
+those documents are sorted by their dates or paths and then placed immediately after the sorted documents.
+
+### Manually Ordering Documents
+
+You can also manually order the documents by setting an `order` metadata with **the filenames listed** in the desired order.
+For example, a collection of tutorials would be configured as:
+
+```yaml
+collections:
+  tutorials:
+    order:
+      - hello-world.md
+      - introduction.md
+      - basic-concepts.md
+      - advanced-concepts.md
+```
+
+Any documents with filenames that do not match the list entry simply gets placed after the rearranged documents. If a document is
+nested under subdirectories, include them in entries as well:
+
+```yaml
+collections:
+  tutorials:
+    order:
+      - hello-world.md
+      - introduction.md
+      - concepts/basics.md
+      - concepts/advanced.md
+```
+
+If both metadata keys have been defined properly, `order` list takes precedence.
+
+## Liquid Attributes
+
+### Collections
+
+Collections are also available under `site.collections`, with the metadata
+you specified in your `_config.yml` (if present) and the following information:
+
+<div class="mobile-side-scroller">
+<table>

+  <h5>A Hard-Coded Collection</h5>
+  <p>In addition to any collections you create yourself, the
+  <code>posts</code> collection is hard-coded into Jekyll. It exists whether
+  you have a <code>_posts</code> directory or not. This is something to note
+  when iterating through <code>site.collections</code> as you may need to
+  filter it out.</p>
+  <p>You may wish to use filters to find your collection:
+  <code>{% raw %}{{ site.collections | where: "label", "myCollection" | first }}{% endraw %}</code></p>
+</div>
+
+<div class="note info">
+  <h5>Collections and Time</h5>
+  <p>Except for documents in hard-coded default collection <code>posts</code>, all documents in collections
+    you create, are accessible via Liquid irrespective of their assigned date, if any, and therefore renderable.
+  </p>
+  <p>Documents are attempted to be written to disk only if the concerned collection
+    metadata has <code>output: true</code>. Additionally, future-dated documents are only written if
+    <code>site.future</code> <em>is also true</em>.
+  </p>
+  <p>More fine-grained control over documents being written to disk can be exercised by setting
+    <code>published: false</code> (<em><code>true</code> by default</em>) in the document's front matter.
+  </p>
+</div>
+
+### Documents
+
+In addition to any front matter provided in the document's corresponding
+file, each document has the following attributes:
+
+<div class="mobile-side-scroller">
+<table>
+  <thead>
+    <tr>
+      <th>Variable</th>
+      <th>Description</th>
+    </tr>

+      </td>
+      <td>
+        <p>
+          The (unrendered) content of the document. If no front matter is
+          provided, Jekyll will not generate the file in your collection. If
+          front matter is used, then this is all the contents of the file
+          after the terminating
+          `---` of the front matter.
+        </p>
