 You can use _Black_ within a GitHub Actions workflow without setting your own Python
 environment. Great for enforcing that your code matches the _Black_ code style.
 
+## Compatibility
+
+This action is known to support all GitHub-hosted runner OSes. In addition, only
+published versions of _Black_ are supported (i.e. whatever is available on PyPI).
+
+Finally, this action installs _Black_ with the `colorama` extra so the `--color` flag
+should work fine.

 ## Usage
 
 Create a file named `.github/workflows/black.yml` inside your repository with:

+
+The version of _Black_ the action will use can be configured via `version`. This can be

+or just the version number if you want an exact version. The action defaults to the
+latest release available on PyPI. Only versions available from PyPI are supported, so no
+commit SHAs or branch names.
+
+If you want to include Jupyter Notebooks, _Black_ must be installed with the `jupyter`
+extra. Installing the extra and including Jupyter Notebook files can be configured via
+`jupyter` (default is `false`).
+
+You can also configure the arguments passed to _Black_ via `options` (defaults to
+`'--check --diff'`) and `src` (default is `'.'`). Please note that the
+[`--check` flag](labels/exit-code) is required so that the workflow fails if _Black_
+finds files that need to be formatted.

+Here's an example configuration:

+- uses: psf/black@stable

+    options: "--check --verbose"
+    src: "./src"
+    jupyter: true
+    version: "21.5b1"
