+It is possible to directly invoke Gradle in your workflow, and the `actions/setup-java@v4` action provides a simple way to cache Gradle dependencies. 
 
 However, the `gradle-build-action` offers a number of advantages over this approach:
 
-- Easily [configure your workflow to use a specific version of Gradle](#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).

 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.
 
 ## Use the action to setup Gradle
 
-The recommended way to use the `gradle-build-action` is in an initial "Setup Gradle" step, with subsquent steps invoking Gradle directly with a `run` step. This makes the action minimally invasive, and allows a workflow to configure and execute a Gradle execution in any way.

+The GitHub [dependency-review-action](https://github.com/actions/dependency-review-action) helps you 
+understand dependency changes (and the security impact of these changes) for a pull request.
+For the `dependency-review-action` to succeed, it must run _after_ the dependency graph has been submitted for a PR.
+
+When using `generate-and-submit`, dependency graph files are submitted at the end of the job, after all steps have been
+executed. For this reason, the `dependency-review-action` must be executed in a dependent job,
+and not as a subsequent step in the job that generates the dependency graph.
+
+Example of a pull request workflow that executes a build for a pull request and runs the `dependency-review-action`:
+
+```yaml
+name: PR check
+
+on:
+  pull_request:
+  
+permissions:
+  contents: write
+  # Note that this permission will not be available if the PR is from a forked repository

+### Integrating `dependency-review-action` for pull request workflows
+
+The GitHub [dependency-review-action](https://github.com/actions/dependency-review-action) helps you 
+understand dependency changes (and the security impact of these changes) for a pull request.
+
+To integrate the `dependency-review-action` into the pull request workflows above, a separate workflow should be added.
+This workflow will be triggered directly on `pull_request`, but will need to wait until the dependency graph results are
+submitted before the dependency review can complete. How long to wait is controlled by the `retry-on-snapshot-warnings` input parameters.
+
+Here's an example of a separate "Dependency Review" workflow that will wait for 10 minutes for the PR check workflow to complete.
+
+```yaml
+name: dependency-review
+on:
+  pull_request:
+
+permissions:
+  contents: read
+  pull-requests: write
+
+jobs:
+  dependency-review:
+    runs-on: ubuntu-latest
+    steps:
+    - name: 'Dependency Review'
+      uses: actions/dependency-review-action@v3
+      with:
+        retry-on-snapshot-warnings: true
+        retry-on-snapshot-warnings-timeout: 600
+```
+
+The `retry-on-snapshot-warnings-timeout` (in seconds) needs to be long enough to allow the entire `run-build-and-generate-dependency-snapshot` and `submit-dependency-snapshot` workflows (above) to complete.

+## Reducing storage costs for saved dependency graph artifacts
+
+When `generate` or `generate-and-submit` is used with the action, the dependency graph that is generated is stored as a workflow artifact. 
+By default, these artifacts are retained for a period of 30 days (or as configured for the repository).
+To reduce storage costs for these artifacts, you can set the `artifact-retention-days` value to a lower number.
+
+```yaml
+    steps:
+    - name: Generate dependency graph, but only retain artifact for one day
+      uses: gradle/gradle-build-action@v2
+      with:
+        dependency-graph: generate
+        artifact-retention-days: 1
+```
+
+
+
+# Gradle Enterprise plugin injection
+
+The `gradle-build-action` provides support for injecting and configuring the Gradle Enterprise Gradle plugin into any Gradle build, without any modification to the project sources.
+This is achieved via an init-script installed into Gradle User Home, which is enabled and parameterized via environment variables.
+
+The same auto-injection behavior is available for the Common Custom User Data Gradle plugin, which enriches any build scans published with additional useful information.
+
+## Enabling Gradle Enterprise injection
+
+In order to enable Gradle Enterprise for your build, you must provide the required configuration via environment variables. 
+
+Here's a minimal example:
+
+```yaml
+name: Run build with Gradle Enterprise injection
+  
+env:
+  GRADLE_ENTERPRISE_INJECTION_ENABLED: true
+  GRADLE_ENTERPRISE_URL: https://ge.gradle.org
+  GRADLE_ENTERPRISE_PLUGIN_VERSION: 3.16.1
+  GRADLE_ENTERPRISE_ACCESS_KEY: ${{ secrets.GE_ACCESS_KEY }} # Required to publish scans to ge.gradle.org
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v4
+    - name: Setup Gradle
+      uses: gradle/gradle-build-action@v2
+    - name: Run a Gradle build with Gradle Enterprise injection enabled
+      run: ./gradlew build
+```
+
+This configuration will automatically apply `v3.16.1` of the [Gradle Enterprise Gradle plugin](https://docs.gradle.com/enterprise/gradle-plugin/), and publish build scans to https://ge.gradle.org.
+
+Note that the `ge.gradle.org` server requires authentication in order to publish scans. The provided `GRADLE_ENTERPRISE_ACCESS_KEY` isn't required by the Gradle Enterprise injection script, 
+but will be used by the GE plugin in order to authenticate with the server.
+
+## Configuring Gradle Enterprise injection
+
+The `init-script` supports a number of additional configuration parameters that you may fine useful. All configuration options (required and optional) are detailed below:
+
+| Variable | Required | Description |
+| --- | --- | --- |
+| GRADLE_ENTERPRISE_INJECTION_ENABLED | :white_check_mark: | enables Gradle Enterprise injection |
+| GRADLE_ENTERPRISE_URL | :white_check_mark: | the URL of the Gradle Enterprise server |
+| GRADLE_ENTERPRISE_ALLOW_UNTRUSTED_SERVER | | allow communication with an untrusted server; set to _true_ if your Gradle Enterprise instance is using a self-signed certificate |
+| GRADLE_ENTERPRISE_ENFORCE_URL | | enforce the configured Gradle Enterprise URL over a URL configured in the project's build; set to _true_ to enforce publication of build scans to the configured Gradle Enterprise URL |
+| GRADLE_ENTERPRISE_PLUGIN_VERSION | :white_check_mark: | the version of the [Gradle Enterprise Gradle plugin](https://docs.gradle.com/enterprise/gradle-plugin/) to apply |
+| GRADLE_ENTERPRISE_CCUD_PLUGIN_VERSION |  | the version of the [Common Custom User Data Gradle plugin](https://github.com/gradle/common-custom-user-data-gradle-plugin) to apply, if any |
+| GRADLE_ENTERPRISE_PLUGIN_REPOSITORY_URL |  | the URL of the repository to use when resolving the GE and CCUD plugins; the Gradle Plugin Portal is used by default |
+
+## Publishing to scans.gradle.com
+
+Gradle Enterprise injection is designed to enable publishing of build scans to a Gradle Enterprise instance,
+and is not suitable for publishing to the public Build Scans instance (https://scans.gradle.com).
+
+In order to publish Build Scans to scans.gradle.com, you need to:
+- Apply the Gradle Enterprise plugin to your build configuration ([see docs](https://docs.gradle.com/enterprise/get-started/#applying_the_plugin))
+- Programmatically accept the Terms of Service for scans.gradle.com ([see docs](https://docs.gradle.com/enterprise/gradle-plugin/#connecting_to_scans_gradle_com))
+- Execute the build with `--scan` or configure your build with `publishAlways()` ([see docs](https://docs.gradle.com/enterprise/get-started/#always_publishing_a_build_scan))
