 ### 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.
