-## Permissions
+## Recommended Permissions
 
 In order to add labels to pull requests, the GitHub labeler action requires write permissions on the pull-request. However, when the action runs on a pull request from a forked repository, GitHub only grants read access tokens for `pull_request` events, at most. If you encounter an `Error: HttpError: Resource not accessible by integration`, it's likely due to these permission constraints. To resolve this issue, you can modify the `on:` section of your workflow to use
 [`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) instead of `pull_request` (see example [above](#create-workflow)). This change allows the action to have write access, because `pull_request_target` alters the [context of the action](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) and safely grants additional permissions. Refer to the [GitHub token permissions documentation](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token) for more details about access levels and event contexts.

 ## Notes regarding `pull_request_target` event
 
 Using the `pull_request_target` event trigger involves several peculiarities related to initial set up of the labeler or updating version of the labeler.
