-This action creates [`repository_dispatch`](https://developer.github.com/v3/repos/#create-a-repository-dispatch-event) events. The default `GITHUB_TOKEN` 
-token can only be used if you are dispatching the same repo. In this case you must assign the permission `action: write` to the token, see [permissions api](https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs). Example:
+This action creates [`repository_dispatch`](https://developer.github.com/v3/repos/#create-a-repository-dispatch-event) events.
+The default `GITHUB_TOKEN` token can only be used if you are dispatching the same repository that the workflow is executing in.
+In this case you must [elevate the token permissions](https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs) to allow the dispatch.

-The solution to trigger other repositories is to manually create a [PAT](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) and store it as a secret e.g. `${{ secrets.PERSONAL_TOKEN }}`.
-
+To dispatch to a remote repository you must create a [Personal Access Token (PAT)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) with the `repo` scope and store it as a secret.
 If you will be dispatching to a public repository then you can use the more limited `public_repo` scope.
