 ## Why use the `gradle-build-action`?

+It is possible to directly invoke Gradle in your workflow, and the `actions/setup-java@v3` action provides a simple way to cache Gradle dependencies.
 
 However, the `gradle-build-action` offers a number of advantages over this approach:
-
 - Easily [run the build with different versions of Gradle](#download-install-and-use-a-specific-gradle-version) using the `gradle-version` parameter. Gradle distributions are automatically downloaded and cached.
 - More sophisticated and more efficient caching of Gradle User Home between invocations, compared to `setup-java` and most custom configurations using `actions/cache`. [More details below](#caching).
 - Detailed reporting of cache usage and cache configuration options allow you to [optimize the use of the GitHub actions cache](#optimizing-cache-effectiveness).

 The `gradle-build-action` is designed to provide these benefits with minimal configuration.
 These features work both when Gradle is executed via the `gradle-build-action` and for any Gradle execution in subsequent steps.
 
-When using `gradle-build-action` we recommend that you _not_ use `actions/cache` or `actions/setup-java@v2` to explicitly cache the Gradle User Home. Doing so may interfere with the caching provided by this action.
