+## Using cs2pr as a GitHub Action
+
+You can also use [`cs2pr` itself as a GitHub Action](https://github.com/staabm/annotate-pull-request-from-checkstyle-action). This is useful if you want to for instance use it for a project that does not use PHP or if you want to use it with a custom PHP installation.
+
+See the example at the [cs2pr GitHub Action repositiory](https://github.com/staabm/annotate-pull-request-from-checkstyle-action#readme).
