 ### Cache Extensions
 
-You can cache PHP extensions using [`shivammathur/cache-extensions`](https://github.com/shivammathur/cache-extensions "GitHub Action to cache php extensions") and [`action/cache`](https://github.com/actions/cache "GitHub Action to cache files") GitHub Actions. Extensions which take very long to setup when cached are available in the next workflow run and are enabled directly. This reduces the workflow execution time.
