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.

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

 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.

+### Kramdown Processor
+
+By default, Jekyll uses the [GitHub Flavored Markdown (GFM) processor](https://github.com/kramdown/parser-gfm) for Kramdown. (Specifying `input: GFM` is fine, but redundant.) GFM supports a couple additional Kramdown options, documented by [kramdown-parser-gfm](https://github.com/kramdown/parser-gfm). These options can be used directly in your Kramdown Jekyll config, like this:
 
-### Example Usage
 ```yaml
 kramdown:
-  html_to_native: true
+  gfm_quirks: [paragraph_end]
 ```
-  
+
+You can also change the processor used by Kramdown (as specified for the `input` key in the [Kramdown RDoc](https://kramdown.gettalong.org/rdoc/Kramdown/Document.html#method-c-new)). For example, to use the non-GFM Kramdown processor in Jekyll, add the following to your configuration.
+
+```yaml
+kramdown:
+  input: Kramdown
+```
+
+Documentation for Kramdown parsers is available in the [Kramdown docs](https://kramdown.gettalong.org/parser/kramdown.html). If you use a Kramdown parser other than Kramdown or GFM, you'll need to add the gem for it.
+
+### Syntax Highlighting (CodeRay)
+
+To use the [CodeRay](http://coderay.rubychan.de/) syntax highlighter with Kramdown, you  need to add a dependency on the `kramdown-syntax-coderay` gem. For example, `bundle add kramdown-syntax-coderay`. Then, you'll be able to specify CodeRay in your `syntax_highlighter` config:
+
+```yaml
+kramdown:
+  syntax_highlighter: coderay
+```
+
+CodeRay supports several of its own configuration options, documented in the [kramdown-syntax-coderay docs](https://github.com/kramdown/syntax-coderay) which can be passed as `syntax_highlighter_opts` like this:
+
+```yaml
+kramdown:
+  syntax_highlighter: coderay
+  syntax_highlighter_opts:
+    line_numbers: table
+    bold_every: 5
+```
+
+### Advanced Kramdown Options
+
+Kramdown supports a variety of other relatively advanced options such as `header_offset` and `smart_quotes`. These are documented in the [Kramdown configuration documentation](https://kramdown.gettalong.org/options.html) and can be added to your Kramdown config like this:
+
+```yaml
+kramdown:
+  header_offset: 2
+```
+

+    Please note that Jekyll uses Kramdown's HTML converter. Kramdown options used only by other converters, such as <code>remove_block_html_tags</code> (used by the RemoveHtmlTags converter), will not work.

+## CommonMark
 
 [CommonMark](https://commonmark.org/) is a rationalized version of Markdown syntax, implemented in C and thus faster than default Kramdown implemented in Ruby. It [slightly differs](https://github.com/commonmark/CommonMark#differences-from-original-markdown) from original Markdown and does not support all the syntax elements implemented in Kramdown, like [Block Inline Attribute Lists](https://kramdown.gettalong.org/syntax.html#block-ials).

 The most basic test that can be run is seeing if `jekyll build` actually works. This is a blocker, a dependency if you will, for other tests you might run on the generate site. So we'll run Jekyll, via Bundler, in the `dependencies` phase.

-with GitHub Pages you can use GitHub Actions.
+When building a Jekyll site with GitHub Pages, Jekyll runs in an environment restricted for security
+reasons, yet containing numerous [whitelisted plugins and themes][ghp-whitelist] to make it simpler
+to get a site set up.
 
+The only workaround to have control over the build environment and gemset yet use GitHub Pages to
+host the site was previously by building elsewhere and pushing the built directory contents to the
+`gh-pages` branch on your repository.
+
+However, GitHub now provides you with the option to use their in-house CI/CD product named
+*GitHub Actions* to *build and deploy (host)* your Jekyll site with complete control over the build
+environment and gemset.
 
 ## Advantages of using Actions
 
 ### Control over gemset
 
-- **Jekyll version** --- Instead of using the currently enabled version at `3.9.0`, you can use any
-  version of Jekyll you want. For example `4.0.0`, or point directly to the repository.
-- **Plugins** --- You can use any Jekyll plugins irrespective of them being on the
-  [supported versions][ghp-whitelist] list, even `*.rb` files placed in the `_plugins` directory
-  of your site.
-- **Themes** --- While using a custom theme is possible without Actions, it is now simpler.
+- **Jekyll version** --- Instead of using the classic GitHub Pages-provided version specified in
+  the [Dependency versions][ghp-whitelist] list, you can use any version of Jekyll you want.
+  For example `{{ site.version }}`, or point directly to the repository via the Gemfile.
+- **Plugins** --- You can use any Jekyll plugins irrespective of them being whitelisted by GitHub,
+  including any `*.rb` files placed in the `_plugins` directory of your site.
+- **Themes** --- While using a custom theme is possible without Actions, it is now possible to use
+  themes depending on features introduced in newer versions of Jekyll.
+
+{: .note .info}
+If you are migrating from the classic flow but want to keep using a GitHub-hosted theme, you may use
+the [jekyll-remote-theme][remote-theme] plugin, add any required dependencies of your theme
+(previously bundled by default) into your `_config.yml` and `Gemfile` and set the
+`remote_theme: <owner>/<repo_name>` theme repository slug correctly in your `_config.yml`.

 ### Setting up the Action
 
-GitHub Actions are registered for a repository by using a YAML file inside the directory path
-`.github/workflows` (note the dot at the start). Here we shall employ
-[Jekyll Actions][jekyll-actions] from the Marketplace for its simplicity.
-
-Create a **workflow file**, say `github-pages.yml`, using either the GitHub interface or by pushing
-a YAML file to the workflow directory path manually. The base contents are:
-
-{% raw %}
-```yaml
-name: Build and deploy Jekyll site to GitHub Pages
-
-on:
-  push:
-    branches:
-      - master
-
-jobs:
-  github-pages:
-    runs-on: ubuntu-16.04
-    steps:
-      - uses: actions/checkout@v2
-      - uses: helaili/jekyll-action@2.0.1
-        env:
-          JEKYLL_PAT: ${{ secrets.JEKYLL_PAT }}
-```
-{% endraw %}
-
-The above workflow can be explained as the following:
-
-- We trigger the build using **on.push** condition for `master` branch only --- this prevents
-  the Action from overwriting the `gh-pages` branch on any feature branch pushes.
-- The **name** of the job matches our YAML filename: `github-pages`.
-- The **checkout** action takes care of cloning your repository.
-- We specify our selected **action** and **version number** using `helaili/jekyll-action@2.0.0`.
-  This handles the build and deploy.
-- We set a reference to a secret **environment variable** for the action to use. The `JEKYLL_PAT`
-  is a *Personal Access Token* and is detailed in the next section.
-
-Instead of using the **on.push** condition, you could trigger your build on a **schedule** by 
-using the [on.schedule] parameter. For example, here we build daily at midnight by specifying
-**cron** syntax, which can be tested at the [crontab guru] site.
-
-```yaml
-on:
-  schedule:
-    - cron:  '0 0 * * *'
-```
-
-Note that this string must be quoted to prevent the asterisks from being evaluated incorrectly.
-
-[on.schedule]: https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#onschedule
-[crontab guru]: https://crontab.guru/
-
-
-### Providing permissions
-
-The action needs permissions to push to your `gh-pages` branch. So you need to create a GitHub
-**authentication token** on your GitHub profile, then set it as an environment variable in your
-build using _Secrets_:
-
-1. On your GitHub profile, under **Developer Settings**, go to the [Personal Access Tokens][tokens]
-   section.
-2. **Create** a token. Give it a name like "GitHub Actions" and ensure it has permissions to
-   `public_repos` (or the entire `repo` scope for private repository) --- necessary for the action
-   to commit to the `gh-pages` branch.
-3. **Copy** the token value.
-4. Go to your repository's **Settings** and then the **Secrets** tab.
-5. **Create** a token named `JEKYLL_PAT` (*important*). Give it a value using the value copied
-   above.
+1. Go to the **Settings** tab on your repository.
+    1. Click **Pages** under **Code and automation**.
+    2. Change **Source** under **Build and deployment** from **Deploy from a branch** to **GitHub Actions**.

-
-```ruby
-source "https://rubygems.org"
-
-gem "github-pages", group: :jekyll_plugins

+
+Once the project is configured with the github-pages environment, it's quite hard to switch back and forth with the local settings and the production-level settings. For that we can use certain CLI options to make the workflow hassle-free.  
+
+```sh
+bundle exec jekyll serve --baseurl=""

-## Install Command Line Tools
-To install the command line tools to compile native extensions, open a terminal and run:
+## Supported macOS versions
 
-```sh
-xcode-select --install
-```
+We match [Homebrew's macOS requirements](https://docs.brew.sh/Installation#macos-requirements), which typically support the last 2 or 3 macOS versions.
+
+Older macOS versions might work, but we don't officially support them.
 
 ## Install Ruby
 
-Jekyll requires **Ruby v{{ site.data.ruby.min_version }}** or higher.
-macOS Catalina 10.15 ships with Ruby 2.6.3. Check your Ruby version using `ruby -v`.
+To install Jekyll on macOS, you need a proper Ruby development environment. 
+While macOS comes preinstalled with Ruby, we don't recommend using that version 
+to install Jekyll. This external article goes over the various reasons 
+[why you shouldn't use the system Ruby](https://www.moncefbelyamani.com/why-you-shouldn-t-use-the-system-ruby-to-install-gems-on-a-mac/).
 
-If you're running a previous version of macOS, you'll have to install a newer version of Ruby.
+Instead, you'll need to install a separate and newer version of Ruby using a 
+version manager such as [asdf], [chruby], [rbenv], or [rvm]. Version managers 
+allow you to easily install multiple versions of Ruby, and switch between them.
 
-### With Homebrew {#brew}
-To run the latest Ruby version you need to install it through [Homebrew](https://brew.sh).
+We recommend `chruby` because it's the simplest and least likely to cause issues. 
+
+The instructions below are an excerpt from this detailed external guide to 
+[install Ruby on Mac]. They work best if you're setting up development tools 
+for the first time on your Mac. If you've already tried to install Ruby or 
+Jekyll on your Mac, or if you run into any issues, read that guide. 
+
+[asdf]: https://asdf-vm.com/
+[chruby]: https://github.com/postmodern/chruby
+[rbenv]: https://github.com/rbenv/rbenv
+[rvm]: https://rvm.io/
+[install Ruby on Mac]: https://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/
+
+### Step 1: Install Homebrew
+
+[Homebrew](https://brew.sh/) makes it easy to install development tools on a Mac.
 
 ```sh
-# Install Homebrew
-/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-
-brew install ruby
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
 ```
 
-Add the brew ruby path to your shell configuration:
+### Step 2: Install chruby and the latest Ruby with ruby-install
 
-```bash
-echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
-```
-
-Relaunch your terminal and check your Ruby setup:
+Install `chruby` and `ruby-install` with Homebrew:
 
 ```sh
-which ruby
-# /usr/local/opt/ruby/bin/ruby
+brew install chruby ruby-install
+```
 
+Install the latest stable version of Ruby (supported by Jekyll):
+
+```sh
+ruby-install ruby {{ site.data.ruby.current_version }}
+```
+
+This will take a few minutes, and once it's done, configure your shell to 
+automatically use `chruby`:
+
+```sh
+echo "source $(brew --prefix)/opt/chruby/share/chruby/chruby.sh" >> ~/.zshrc
+echo "source $(brew --prefix)/opt/chruby/share/chruby/auto.sh" >> ~/.zshrc
+echo "chruby ruby-{{ site.data.ruby.current_version }}" >> ~/.zshrc # run 'chruby' to see actual version
+```
+
+If you're using Bash, replace `.zshrc` with `.bash_profile`. If you're not sure, 
+read this external guide to 
+[find out which shell you're using](https://www.moncefbelyamani.com/which-shell-am-i-using-how-can-i-switch/).
+
+Quit and relaunch Terminal, then check that everything is working:
+
+```sh
 ruby -v
-{{ site.data.ruby.current_version_output }}
 ```
 
-You're now running the current stable version of Ruby!
+It should show {{ site.data.ruby.current_version_output }} or a newer version.
 
-### With rbenv {#rbenv}
-
-People often use [rbenv](https://github.com/rbenv/rbenv) to manage multiple
-Ruby versions. This is very useful when you need to be able to run a given Ruby version on a project.
-
-```sh
-# Install Homebrew
-/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-
-# Install rbenv and ruby-build
-brew install rbenv
-
-# Set up rbenv integration with your shell
-rbenv init
-
-# Check your installation
-curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash
-```
-
-Restart your terminal to apply your changes.
-Next, you can install the Ruby version you want. Let's install the latest stable version:
-
-```sh
-rbenv install {{ site.data.ruby.current_version }}
-rbenv global {{ site.data.ruby.current_version }}
-ruby -v
-{{ site.data.ruby.current_version_output }}
-```
-
-That's it! Head over to [rbenv command references](https://github.com/rbenv/rbenv#command-reference) to learn how to use different versions of Ruby in your projects.
+Next, read that same external guide for important notes about 
+[setting and switching between Ruby versions with chruby](https://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/#how-to-install-different-versions-of-ruby-and-switch-between-them).
 
 ## Install Jekyll
 
-After installing Ruby, install Jekyll and Bundler.
-
-### Local Install
-
-Install the bundler and jekyll gems:
+After installing Ruby with chruby, install the latest Jekyll gem:
 
 ```sh
-gem install --user-install bundler jekyll
-```
-
-Get your Ruby version:
-
-```sh
-ruby -v
-{{ site.data.ruby.current_version_output }}
-```
-
-Append your path file with the following, replacing the `X.X` with the first two digits of your Ruby version:
-
-```bash
-echo 'export PATH="$HOME/.gem/ruby/X.X.0/bin:$PATH"' >> ~/.bash_profile
-```
-
-Check that `GEM PATHS:` points to your home directory:
-
-```sh
-gem env
-```
-
-{: .note .info}
-Every time you update Ruby to a version in which the first two digits change, update your path to match.
-
-### Global Install
-
-{: .note .warning}
-We recommend not installing Ruby gems globally to avoid file permissions problems and using `sudo`.
-
-#### On Mojave (10.14)
-
-Because of SIP Protections in Mojave, run:
-
-```sh
-sudo gem install bundler
-sudo gem install -n /usr/local/bin/ jekyll
-```
-
-#### Before Mojave (<10.14)
-
-Run:
-
-```sh
-sudo gem install bundler jekyll
+gem install jekyll

 ### 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
+The version will mostly be of the format `"major.minor.patch"`. At times, we may decide to ship pre-releases which will be in the format
+`"major.minor.patch.suffix"`. `suffix` is not standardized and may be anything like `pre.alpha1`, `pre.rc2`, or simply `beta3`, etc.

+  - Add `suffix` if applicable.
+  - For example, `"3.9.1" => "4.0.0"` or, `"3.9.1 => "4.0.0.alpha1"`.
+  - Skip to next step in the release process.
+
+- If there's a subsection titled `Minor Enhancements`
+  - Increment just the `minor` component and reset the patch component to `0`.
+  - Add `suffix` if applicable.
+  - For example, `"4.0.2" => "4.1.0"` or `"4.1.0" => "4.2.0.pre"`.
+  - Skip to next step in the release process.
+
+- For anything else, increment just the `patch` component or `suffix` component as applicable. For example, `"4.0.2" => "4.0.3"` or
+  `"4.1.0.beta3" => "4.1.0.rc"`.
+
+### Write a release post

+title: Releasing off older stable branches
+---
+
+Apart from having releases cut from the default `master` branch, Jekyll Core may occasionally cut releases containing security patches and
+critical bug-fixes for older versions under maintenance. Such releases are cut from specially named branches, following the pattern
+`[x].[y]-stable` where `[x]` denotes semver-major-version and `[y]`, the semver-minor-version. For example, the branch `3.9-stable` refers to
+commits released as part of `jekyll-3.9.x` series.
+
+Co-ordinating a release off a `*-stable` branch is complicated mainly because the default branch has to inevitably reflect the release as well.
+
+## Requirements
+
+- The maintainer has to have **write-access** to both the concerned `*-stable` and `master` branches.
+- The maintainer needs to complete the task using their **local CLI program** instead of dispatching via GitHub Web UI.
+- The maintainer is abreast with the workflow to [release off `master`]({{ 'docs/maintaining/releasing-a-new-version/' | relative_url }}). The
+  procedure documented in the following section is an abridged adaptation of the workflow for `master`.
+- A release post has been drafted and **is awaiting publish to `master`** via an approved pull request.
+- Stable internet connection.
+
+## Trigger release workflow
+
+1. Ensure that you've **checked out the concerned `*-stable` branch** and is up-to-date with its counterpart at `jekyll/jekyll` at GitHub.
+2. Bump the `VERSION` string in `lib/jekyll/version.rb`.
+3. Update the **History document** as documented [here]({{ 'docs/maintaining/releasing-a-new-version/#update-the-history-document' | relative_url }}).<br/>
+   (**IMPORTANT: Do not run `rake site:generate` on the stable branch though**).
+4. Copy the entire History section pertaining to current release and paste into a new tab / window of your text-editor. We will use this
+   temporary snippet at a future stage.
+5. Commit changes to the version-file and History document with commit message `Release :gem: v[CURRENT_VERSION]`.
+6. Push commit to upstream remote `jekyll/jekyll` at GitHub.
+
+## Publish release post
+
+1. Ensure the `Release Gem` workflow has completed successfully.
+2. Merge release-post pull request to `master`.
+
+## Update default branch to reflect release off the stable branch
+
+1. Locally, check out `master` and ensure it is up-to-date with its remote counterpart at `jekyll/jekyll` at GitHub.
+2. Update History document using the snippet in the temporary tab / window created earlier. The various sections in the History document are
+   primarily in reverse chronological order and secondarily scoped to the semver-major-version. For example, a release section for `v3.9.2`
+   will be listed above the section for `v3.9.1` but under release sections for v4.x.
+   The snippet stashed earlier has to be injected into the correct location manually.
+3. Optionally, update `VERSION` string in `lib/jekyll/version.rb`. (*If existing version is lesser than latest version*).
+4. Now **run `rake site:generate`** to update various meta files:
+     - docs/_config.yml
+     - docs/_docs/history.md
+     - docs/latest_version.txt
+5. Commit changes to various meta files with commit message `Release :gem: v[CURRENT_VERSION]`.
+6. Push commit to upstream remote.
+
+## Publish GitHub Release
+
+Unlike releases cut off the `master` branch, our JekyllBot does not automatically create and publish a GitHub Release for tags created from
+*non-default* branches. Therefore, the maintainer has to **manually create and publish** the concerned GitHub Release.
+1. Choose the newly pushed tag.
+2. Title is same as the name of the selected tag.
+3. The release snippet stashed previously forms the body.
+4. Delete the snippet's title (`## x.y.z / YYYY-MM-DD`) from the release body.
+5. Publish.
+
+Note: The GitHub Release may optionally be *drafted* prior to updating the default branch and then *published* immediately after pushing the
+update commit to the default branch to streamline the procedure.

-You have 3 options for installing plugins:
+Jekyll has built-in support for using plugins to extend the core functionality.
 
-1. In your site source root, make a `_plugins` directory. Place your plugins
-   here. Any file ending in `*.rb` inside this directory will be loaded before
-   Jekyll generates your site.
+Primarily, any file with extension `.rb` placed within a `_plugins` directory at the root of the site's `source`, will be automatically loaded
+during a build session.
 
-2. In your `_config.yml` file, add a new array with the key `plugins` (or `gems` for Jekyll < `3.5.0`) and the
-   values of the gem names of the plugins you'd like to use. An example:
+This behavior can be configured as follows:
 
-   ```yaml
-   # This will require each of these plugins automatically.
-   plugins:
-     - jekyll-gist
-     - jekyll-coffeescript
-     - jekyll-assets
-     - another-jekyll-plugin
-   ```
+- The `_plugins` directory may be changed either directly via the command-line or via the configuration file(s).
+- Plugins in the `_plugins` directory (or its equivalent(s)) will not be loaded when Jekyll is running in `safe` mode.
+- This route cannot be used to extend the Jekyll CLI.
 
-   Then install your plugins using `gem install jekyll-gist jekyll-coffeescript jekyll-assets another-jekyll-plugin`
+To work with plugins packaged as gems, one has to list the desired gems in the configuration file under a top-level key named `plugins`.
+Additionally, if you're building in `safe` mode, the gem needs to be listed under a top-level key named `whitelist`. For example:
 
-3. Add the relevant plugins to a Bundler group in your `Gemfile`. An
-   example:
+```yaml
+plugins:
+  - jekyll-gist
+  - jekyll-coffeescript
+  - jekyll-seo-tag
+  - some-other-jekyll-plugin
 
-   ```ruby
-   group :jekyll_plugins do
-     gem "jekyll-gist"
-     gem "jekyll-coffeescript"
-     gem "jekyll-assets"
-     gem "another-jekyll-plugin"
-   end
-   ```
+# Enable safe mode
+safe: true
 
-   Now you need to install all plugins from your Bundler group by running single command `bundle install`.
+# Whitelist plugins under safe mode.
+# Note that `some-other-jekyll-plugin` is not listed here. Therefore,
+# it will not be loaded under safe mode.
+whitelist:
+  - jekyll-gist
+  - jekyll-coffeescript
+  - jekyll-seo-tag
+```
+
+In the absence of a Gemfile, one must manually ensure that listed plugins have been installed prior to invoking Jekyll. For example, the
+latest versions of gems in the above list may be installed to a system-wide location by running:
+
+```sh
+gem install jekyll-gist jekyll-coffeescript jekyll-remote-theme some-other-jekyll-plugin
+```
+
+## Using a Gemfile
+
+The maintenance of various gem dependencies may be greatly simplified by using a Gemfile (usually at the root of the site's source) in
+conjunction with a Rubygem named `bundler`. The Gemfile however **should** list all the primary dependencies of your site, including Jekyll
+itself, not just gem-based plugins of the site because Bundler narrows the scope of installed gems to just *runtime dependencies* resolved by
+evaluating the Gemfile. For example:
+
+```ruby
+source "https://rubygems.org"
+
+# Use the latest version.
+gem "jekyll"
+
+# The theme of current site, locked to a certain version.
+gem "minima", "2.4.1"
+
+# Plugins of this site loaded during a build with proper
+# site configuration.
+gem "jekyll-gist"
+gem "jekyll-coffeescript"
+gem "jekyll-seo-tag", "~> 1.5"
+gem "some-other-jekyll-plugin"
+
+# A dependency of a custom-plugin inside `_plugins` directory.
+gem "nokogiri", "~> 1.11"
+```
+
+The gems listed in the Gemfile can be collectively installed by simply running `bundle install`.
+
+### The `:jekyll_plugins` Gemfile group
+{: #the-jekyll_plugins-group}
+
+Jekyll gives a special treatment to gems listed as part of the `:jekyll_plugins` group in a Gemfile. Any gem under this group is loaded at
+the very beginning of any Jekyll process, irrespective of the `--safe` CLI flag or entries in the configuration file(s).
+
+While this route allows one to enhance Jekyll's CLI with additional subcommands and options, or avoid having to list gems in the configuration
+file, the downside is the necessity to be mindful of what gems are included in the group. For example:
+
+```ruby
+source "https://rubygems.org"
+
+# Use the latest version.
+gem "jekyll"
+
+# The theme of current site, locked to a certain version.
+gem "minima", "2.4.1"
+
+# Plugins of this site loaded only if configured correctly.
+gem "jekyll-gist"
+gem "jekyll-coffeescript"
+
+# Gems loaded irrespective of site configuration.
+group :jekyll_plugins do
+  gem "jekyll-cli-plus"
+  gem "jekyll-seo-tag", "~> 1.5"
+  gem "some-other-jekyll-plugin"
+end
+```
