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.

+
+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 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.

+### Configuration methods
 
-### Configuration File
+To specify settings for the dependency review action, you can choose from two options:
 
-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.
+- [Option 1: Inline the configuration options]() in your workflow file.
+- [Option 2: Reference an external configuration file]() in 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.                                                         |
+#### Option 1: Using inline configuration
 
-#### Example
+You can pass configuration options to the dependency review action using your workflow file.
 
-Start by specifying that you will be using an external configuration 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
-  uses: actions/dependency-review-action@v4
-  with:
-    config-file: './.github/dependency-review-config.yml'
-```
+   ```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:
+             fail-on-severity: moderate
 
-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**:
+             # Use comma-separated names to pass list arguments:
+             deny-licenses: LGPL-2.0, BSD-2-Clause
+   ```
 
-```yaml
-fail_on_severity: 'critical'
-allow_licenses:
-  - 'GPL-3.0'
-  - 'BSD-3-Clause'
-  - 'MIT'
-```
+#### Option 2: Using an external configuration file
 
-For more examples of how to use this action and its configuration options, see the [examples](docs/examples.md) page.
+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.
 
-### Considerations
+1. In the same YAML workflow file you created during installation, use `config-file` to specify that you are using an external configuration file.
 
-- Checking for licenses is not supported on Enterprise Server as the API does not return license information.
-- The `allow-licenses` and `deny-licenses` options are mutually exclusive; 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**.
+   ```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'
+   ```

-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/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/about-protected-branches#require-status-checks-before-merging).
+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.
+
+   ```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'

+   | --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------- |
+   | `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'
+   ```
+
+#### `OTHER` in license strings
+
+License data comes from [ClearlyDefined](https://clearlydefined.io) and you may sometimes see licenses displayed with the string `OTHER` in them. ClearlyDefined [defines OTHER](https://docs.clearlydefined.io/docs/curation/curation-guidelines) as:
+
+> This indicates that a human confirmed that there is license information in the file but that the license is not an SPDX-identified license.
+
+`OTHER` is not a valid [SPDX license identifier](https://spdx.org/licenses/), so we convert `OTHER` in a license string into `LicenseRef-clearlydefined-OTHER`, which _is_ valid in SPDX. If you want to add that to the deny or allow list, be sure to add `LicenseRef-clearlydefined-OTHER` to this list, because that is what we'll actually be comparing.
+
+#### Further information

+- 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.
+
+## 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.
+  - `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]
