+Get all changed/modified files in a pull request (`pull_request` or `pull_request_target`) or push's commits.
 You can choose to get all changed files, only added files, only modified files, only removed files, only renamed files, or all added and modified files.
 These outputs are available via the `steps` output context.
 The `steps` output context exposes the output names `all`, `added`, `modified`, `removed`, `renamed`, and `added_modified`.
+Renamed files that are also modified are included in `renamed`, `modified` and `added_modified`.

-## Scenarios
+### Filtering
+
+You can filter files using regular expressions with the `filter` option.
+This option receives a list of patterns using [GitHub Actions syntax](https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#filter-pattern-cheat-sheet).
+You can use `!` at the start of a pattern to negate previous positive patterns.
+See the [Get all changed `*.yml` files but exclude `.github/*/*.yml` files](#get-all-changed-yml-files-but-exclude-githubyml-files) example.

 Be careful that the order of the glob has an importance.
 Therefore, including all YML files first and excluding the YML files of your `.github/*/` directories is the way to go to exclude them.
 If those two globs were inverted, you **would** include all the YML files, with the ones in your `.github/*/` directories.
