 ## :wrench: PHP Extension Support
-- On `ubuntu` extensions which have the package in `APT` are installed. If extension is not in `APT`, you can use `PECL` to install the extension as fallback by specifying `pecl: true`. 
+- On `ubuntu` by default extensions which are available as a package can be installed. If the extension is not available as a package but it is on `PECL`, it can be installed by specifying `pecl: true`. 
 - On `windows` extensions which have `windows` binary on `PECL` can be installed.
 - On `macOS` extensions which are on `PECL` can be installed.
 - Extensions which are installed along with PHP if specified are enabled.

 ### Cache dependencies
 
-You can persist composer's internal cache directory using the [`action/cache`](https://github.com/actions/cache) 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.

 **Note:** Please do not cache `vendor` directory using `action/cache` as that will have side-effects.
