+Compared to [actions/setup-ruby](https://github.com/actions/setup-ruby),
+this actions supports many more versions and features.
+
 ### Supported Versions
 
 This action currently supports these versions of MRI, JRuby and TruffleRuby:
 
 | Interpreter | Versions |
 | ----------- | -------- |
-| Ruby | 2.3.0 - 2.3.8, 2.4.0 - 2.4.9, 2.5.0 - 2.5.7, 2.6.0 - 2.6.5, 2.7.0 |
-| JRuby | 9.2.9.0 |
-| TruffleRuby  | 19.3.0, 19.3.1 |
+| Ruby | 2.2, 2.3.0 - 2.3.8, 2.4.0 - 2.4.9, 2.5.0 - 2.5.7, 2.6.0 - 2.6.5, 2.7.0, head, mingw, mswin |
+| JRuby | 9.2.9.0 - 9.2.10.0, head |
+| TruffleRuby | 19.3.0 - 20.0.0, head |
+| Rubinius | 4.14 |
 
-The recommended way to refer to these versions is:
-`2.3`, `2.4`, `2.5`, `2.6`, `2.7`, `jruby`, `truffleruby`.  
-That way, the latest compatible release is used, which contains the most bug fixes.
-
-See https://github.com/eregon/ruby-install-builder/blob/metadata/versions.json
-for the always up-to-date list of available Ruby versions.
-
-Note that Ruby 2.3 and the OpenSSL version it needs (1.0.2) are both end-of-life,
-which means Ruby 2.3 is unmaintained and considered insecure.
+`mingw` and `mswin` are `ruby-head` builds using the MSYS2 and MSVC toolchains on Windows.  
+Note that Ruby ≤ 2.3 and the OpenSSL version it needs (1.0.2) are both end-of-life,
+which means Ruby ≤ 2.3 is unmaintained and considered insecure.
 On Windows, Ruby 2.4 uses OpenSSL 1.0.2, which is no longer maintained.
+Ruby 2.2 resolves to 2.2.6 on Windows (last build from RubyInstaller) and 2.2.10 otherwise.
 
 ### Supported Platforms
 
-The action works for all GitHub-hosted runners:
-`ubuntu-16.04`, `ubuntu-18.04`, `macos-latest` and `windows-latest`.
+The action works for all [GitHub-hosted runners](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/virtual-environments-for-github-hosted-runners).
 
-Ruby 2.3, JRuby and TruffleRuby are not yet supported on `windows-latest`.
+| Operating System | Versions |
+| ----------- | -------- |
+| Ubuntu  | `ubuntu-latest` (= `ubuntu-18.04`), `ubuntu-16.04` |
+| macOS   | `macos-latest` |
+| Windows | `windows-latest` |
 
-The prebuilt rubies are generated by https://github.com/eregon/ruby-install-builder
-and on Windows by https://github.com/oneclick/rubyinstaller2.
+Rubinius is only available on `ubuntu-latest`.
+
+The prebuilt releases are generated by [ruby-builder](https://github.com/ruby/ruby-builder)
+and on Windows by [RubyInstaller2](https://github.com/oneclick/rubyinstaller2).
+`mingw` and `mswin` builds are generated by [ruby-loco](https://github.com/MSP-Greg/ruby-loco).
+`ruby-head` is generated by [ruby-dev-builder](https://github.com/ruby/ruby-dev-builder),
+`jruby-head` is generated by [jruby-dev-builder](https://github.com/ruby/jruby-dev-builder)
+and `truffleruby-head` is generated by [truffleruby-dev-builder](https://github.com/ruby/truffleruby-dev-builder).
+The full list of available Ruby versions can be seen in [ruby-builder-versions.js](ruby-builder-versions.js)
+for Ubuntu and macOS and in [windows-versions.js](windows-versions.js) for Windows.

+## Windows
+
+Note that running CI on Windows can be quite challenging if you are not very familiar with Windows.
+It is recommended to first get your build working on Ubuntu and macOS before trying Windows.
+
+* The default shell on Windows is not Bash but [PowerShell](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions#using-a-specific-shell).
+  This can lead issues such as multi-line scripts [not working as expected](https://github.com/ruby/setup-ruby/issues/13).
+* The `PATH` contains [multiple compiler toolchains](https://github.com/ruby/setup-ruby/issues/19). Use `where.exe` to debug which tool is used.
+* MSYS2 is prepended to the `PATH`, similar to what RubyInstaller2 does.
+* JRuby on Windows has a known bug that `bundle exec rake` [fails](https://github.com/ruby/setup-ruby/issues/18).
+
 ## Limitations
 
 * This action currently only works with GitHub-hosted runners, not private runners.
 
+## Versioning
+
+This action follows semantic versioning with a moving `v1` branch.
+This follows the [recommendations](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md) of GitHub Actions.
+
 ## Credits
 
+The current maintainer of this action is @eregon.
 Most of the Windows logic is from https://github.com/MSP-Greg/actions-ruby by MSP-Greg.
+Many thanks to MSP-Greg and Lars Kanis for the help with Ruby Installer.
