 ### Cache dependencies
 
 You can persist composer's internal cache directory using the [`action/cache`](https://github.com/actions/cache "GitHub Action to cache files") GitHub Action. Dependencies cached are loaded directly instead of downloading them while installation. The files cached are available across check-runs and will reduce the workflow execution time.

+### Problem Matchers
+
+You can setup problem matchers for your `PHPUnit` output. This will scan the errors in your tests and surface that information prominently in the GitHub Actions UI by creating annotations and log file decorations.
