-### How it works
+## Bug reports and other issues

-This Action makes an authenticated query to the Dependency Graph Diff
-API endpoint (`GET /repos/{owner}/{repo}/dependency-graph/compare/{basehead}`)
-to find out the set of added and removed dependencies for each manifest.
+If you've encountered a problem, please let us know by [submitting an issue](https://github.com/actions/dependency-review-action/issues/new)!

-### Bootstrapping the project
+## Enhancements and feature requests

-```
-git clone https://github.com/actions/dependency-review-action.git
-cd dependency-review-action
-npm install
-```
+If you've got an idea for a new feature, please submit as [an issue](https://github.com/actions/dependency-review-action/issues/new) so that the community can see it, and we can discuss it there. We may not be able to respond to every single issue, but will make a best effort!

-### Running the tests
+If you'd like to make a contribution yourself, we ask that before significant effort is put into code changes, that we have agreement that the change aligns with our strategy for the action. Since this is a verified Action owned by GitHub we want to make sure that contributions are high quality, and that they maintain consistency with the rest of the action's behavior.

-```
-npm run test
-```
+1. Create an [issue discussing the idea](https://github.com/actions/dependency-review-action/issues/new), so that we can discuss it there.
+2. If we agree to incorporate the idea into the action, please write-up a high level summary of the approach that you plan to take so we can review

-_Note_: We don't have any useful tests yet, contributions are welcome!
+## Stalebot

-## Local Development
+We have begun using a [Stalebot action](https://github.com/actions/stale) to help keep the Issues and Pull requests backlogs tidy. You can see the configuration [here](.github/workflows/stalebot.yml). If you'd like to keep an issue open after getting a stalebot warning, simply comment on it and it'll reset the clock.

+## Development lifecycle
+
+Ready to contribute to `dependency-review-action`?  Here is some information to help you get started.
+
+### High level overview of the action
+
+This action makes an authenticated query to the [Dependency Review API](https://docs.github.com/en/rest/dependency-graph/dependency-review) endpoint (`GET /repos/{owner}/{repo}/dependency-graph/compare/{basehead}`) to find out the set of added and removed dependencies for each manifest.
+
+The action then evaluates the differences between the pushes based on the the rules defined in the action configuration, and summarizes the differences and any violations of the rules you have defined as a comment in the pull request that triggered it and the action outputs.
+
+### Local Development
+
+Before you begin, you need to have [Node.js](https://nodejs.org/en/) installed, minimum version 18.

-#### Example
+> [!NOTE]
+> - \* Not supported for use with GitHub Enterprise Server. (Checking for licenses is not supported on GitHub Enterprise Server because the API does not return license information.)
+> - \+ When `warn-only` is set to `true`, all vulnerabilities, independently of the severity, will be reported as warnings and the action will not fail.
+> - The `allow-licenses` and `deny-licenses` options are mutually exclusive; an error will be raised if you provide both.
+> - If we can't detect the license for a dependency **we will inform you, but the action won't fail**.

+To specify settings for the dependency review action, you can choose from two options:
+- [Option 1: Inline the configuration options]() in your workflow file.
+- [Option 2: Reference an external configuration file]() in your workflow file.

-### Configuration File
+#### Option 1: Using inline configuration

-You can use an external configuration file to specify the settings for this action. It can be a local file or a file in an external repository. Refer to the following options for the specification.
+You can pass configuration options to the dependency review action using your workflow file.

-| Option                | Usage                                                                                                                                                                                                                                                     | Possible values                                                                                                                      |
-| --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
-| `config-file`         | A path to a file in the current repository or an external repository. Use this syntax for external files: `OWNER/REPOSITORY/FILENAME@BRANCH`                                                                                                              | **Local file**: `./.github/dependency-review-config.yml` <br> **External repo**: `github/octorepo/dependency-review-config.yml@main` |
-| `external-repo-token` | Specifies a token for fetching the configuration file. It is required if the file resides in a private external repository and for all GitHub Enterprise Server repositories. Create a token in [developer settings](https://github.com/settings/tokens). | Any token with `read` permissions to the repository hosting the config file.                                                         |
+1. In the same YAML workflow file you created during installation, use the `with:` key to specify your chosen settings:
+   ```yaml
+   name: 'Dependency Review'
+   on: [pull_request]
+   permissions:
+     contents: read
+   jobs:
+     dependency-review:

+       steps:
+         - name: 'Checkout Repository'

-#### Example
+             # Use comma-separated names to pass list arguments:
+             deny-licenses: LGPL-2.0, BSD-2-Clause
+   ```

-Start by specifying that you will be using an external configuration file:
+#### Option 2: Using an external configuration file

-```yaml
- name: Dependency Review
-  uses: actions/dependency-review-action@v3
-  with:
-    config-file: './.github/dependency-review-config.yml'
-```
+You can use an external configuration file to specify settings for this action. The file can be a local file or a file in an external repository. 

-And then create the file in the path you just specified. Please note
-that the **option names in external files use underscores instead of dashes**:
+1. In the same YAML workflow file you created during installation, use `config-file` to specify that you are using an external configuration file.

-```yaml
-fail_on_severity: 'critical'
-allow_licenses:
-  - 'GPL-3.0'
-  - 'BSD-3-Clause'
-  - 'MIT'
-```
+   ```yaml
+   name: 'Dependency Review'
+   on: [pull_request]
+   permissions:
+     contents: read
+   jobs:
+     dependency-review:
+       runs-on: ubuntu-latest
+       steps:
+         - name: 'Checkout Repository'
+           uses: actions/checkout@v4
+         - name: Dependency Review
+           uses: actions/dependency-review-action@v4
+           with:
+             config-file: './.github/dependency-review-config.yml'
+   ```
+   | Option                | Usage    | Possible values | 
+   |--------------------- | ----------- | ----------------------------- |
+   | `config-file`         | A path to a file in the current repository or an external repository. Use this syntax for external files: `OWNER/REPOSITORY/FILENAME@BRANCH`                                                                                                              | **Local file**: `./.github/dependency-review-config.yml` <br> **External repo**: `github/octorepo/dependency-review-config.yml@main` |
+2. Optionally, if the file resides in a private external repository, and for all GitHub Enterprise Server repositories, use `external-repo-token` to specify a token for fetching the file.

-For more examples of how to use this action and its configuration options, see the [examples](docs/examples.md) page.
+   ```yaml
+    - name: Dependency Review
+      uses: actions/dependency-review-action@v4
+      with:
+        config-file: 'github/octorepo/dependency-review-config.yml@main'
+        external-repo-token: 'ghp_123456789abcde'
+   ```

-### Considerations
+   | Option                | Usage    | Possible values | 
+   |--------------------- | ----------- | ----------------------------- |
+   | `external-repo-token` | Specifies a token for fetching the configuration file. It is required if the file resides in a private external repository and for all GitHub Enterprise Server repositories. Create a token in [developer settings](https://github.com/settings/tokens). | Any token with `read` permissions to the repository hosting the config file. |
+3. Create the configuration file in the path you specified for `config-file`.
+4. In the configuration file, specify your chosen settings.
+   ```yaml
+   fail_on_severity: 'critical'
+   allow_licenses:
+     - 'GPL-3.0'
+     - 'BSD-3-Clause'
+     - 'MIT'
+   ```
+> [!NOTE]
+> For external configuration files, the option names use underscores instead of dashes.
+> Example: `fail_on_severity`

- Checking for licenses is not supported on Enterprise Server as the API does not return license information.
- The action will only accept one of the two `license` parameters; an error will be raised if you provide both.
- We don't have license information for all of your dependents. If we can't detect the license for a dependency **we will inform you, but the action won't fail**.
+#### Further information

-## Blocking pull requests
+- For more examples of how to use this action and its configuration options, see the [examples](docs/examples.md) page.
+- For general information about dependency review on GitHub, see "[About dependency review](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/about-dependency-review)" in the GitHub Docs documentation.

-The Dependency Review GitHub Action check will only block a pull request from being merged if the repository owner has required the check to pass before merging. For more information, see the [documentation on protected branches](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/about-protected-branches#require-status-checks-before-merging).
+## Using dependency review action to block a pull request from being merged
+
+You can configure your repository to block a pull request from being merged if the pull request fails the dependency review action check. To do this, the repository owner must configure branch protection settings that require the check to pass before merging. For more information, see "[Require status checks before merging](https://docs.github.com/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/about-protected-branches#require-status-checks-before-merging)" in GitHub Docs documentation.   
+
+## Outputs
+
+Dependency review action can create [outputs](https://docs.github.com/en/actions/using-jobs/defining-outputs-for-jobs), so that data from its execution can be used by other jobs in a workflow.
+
+- `comment-content` is generated with the same content as would be present in a Dependency Review Action comment.
+- `dependency-changes` holds all dependency changes in a JSON format. The following outputs are subsets of `dependency-changes` filtered based on the configuration:
+  - `vulnerable-changes` holds information about dependency changes with vulnerable dependencies in a JSON format.
+  - `invalid-license-changes` holds information about invalid or non-compliant license dependency changes in a JSON format.
+  - `denied-changes` holds information about denied dependency changes in a JSON format.
+
+> [!NOTE]
+> Action outputs are unicode strings [with a 1MB size limit](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#outputs-for-docker-container-and-javascript-actions).   
+>
+> If you use these outputs in a run-step, you must store the output data in an environment variable instead of using the output directly. Using an output directly might break shell scripts. For example:
+>
+> ```yaml
+> env:
+>   VULNERABLE_CHANGES: ${{ steps.review.outputs.vulnerable-changes }}
+> run: |
+>   echo "$VULNERABLE_CHANGES" | jq
+> ```
+>
+> instead of direct `echo '${{ steps.review.outputs.vulnerable-changes }}'`. 
+> See [examples](docs/examples.md) for more.

 ## Exclude dependencies from their name or groups

-Using the `deny-packages` option you can exclude dependencies by their PURL. You can add multiple values separated by a commas.
+With the `deny-packages` option, you can exclude dependencies based on their PURL (Package URL). If a specific version is provided, the action will deny packages matching that version. When no version is specified, the action treats it as a wildcard, denying all matching packages regardless of version. Multiple values can be added, separated by commas.
+
 Using the `deny-groups` option you can exclude dependencies by their group name/namespace. You can add multiple values separated by a comma.

-In this example, we are excluding `pkg:maven/org.apache.logging.log4j:log4j-api` and `pkg:maven/org.apache.logging.log4j/log4j-core` from `maven` and all packages in the group `pkg:maven/com.bazaarvoice.maven`
