+## Caching
+
+This action provides 3 levels of caching to help speed up your GitHub Actions:
+
+- `wrapper` caches the local [wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html) installation, saving time downloading and unpacking Gradle distributions ;
+- `dependencies` caches the [dependencies](https://docs.gradle.org/current/userguide/dependency_resolution.html#sub:cache_copy), saving time downloading dependencies ;
+- `configuration` caches the [build configuration](https://docs.gradle.org/nightly/userguide/configuration_cache.html), saving time configuring the build.
+
+Only the first one, caching the wrapper installation, is enabled by default.
+Future versions of this action will enable all caching by default.
+
+You can control which level is enabled as follows:
+
+```yaml
+wrapper-cache-enabled: true
+dependencies-cache-enabled: true
+configuration-cache-enabled: true
+```
+
+The wrapper installation cache is simple and can't be configured further.
+
+The dependencies and configuration cache will compute a cache key in a best effort manner.
+Keep reading to learn how to better control how they work.
+
+### Configuring the dependencies and configuration caches
+
+Both the dependencies and configuration caches use the same default configuration:
+
+They use the following inputs to calculate the cache key:
+```text
+
+
+```
+
+They restore cached state even if there isn't an exact match.
+
+If the defaults don't suit your needs you can override them with the following inputs:
+
+```yaml
+dependencies-cache-key: |
+  **/gradle.properties
+  gradle/dependency-locking/**
+dependencies-cache-exact: true
+configuration-cache-key: |
+  **/gradle.properties
+  gradle/dependency-locking/**
+configuration-cache-exact: true
+```
+
+Coming up with a good cache key isn't trivial and depends on your build.
+The above example isn't realistic.
+Stick to the defaults unless you know what you are doing.
+
+If you happen to use Gradle [dependency locking](https://docs.gradle.org/current/userguide/dependency_locking.html) you can make the dependencies cache more precise with the following configuration:
+
+```yaml
+dependencies-cache-enabled: true
+dependencies-cache-key: gradle/dependency-locking/**
+dependencies-cache-exact: true
+```
+
+## Build scans
 
 If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-command-action` action will emit the link to the published build scan as an output named `build-scan-url`.
