@@ -30,6 +30,7 @@ A GitHub action for styling files with [prettier](https://prettier.io).
 | clean_node_folder | :x: | `true` | Delete the node_modules folder before committing |
 | only_changed | :x: | `false` | Only prettify changed files, can't be used with file_pattern! This command works only with the checkout action set to fetch depth '0' (see example 2)|
 | github_token | :x: | `${{ github.token }}` | The default [GITHUB_TOKEN](https://docs.github.com/en/actions/reference/authentication-in-a-workflow#about-the-github_token-secret) or a [Personal Access Token](https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token)
+| git_identity | :x: | `actions` | Set to `author` to use author's user as committer. This allows triggering [further workflow runs](https://github.com/peter-evans/create-pull-request/blob/main/docs/concepts-guidelines.md#triggering-further-workflow-runs) 
 
 > Note: using the same_commit option may lead to problems if other actions are relying on the commit being the same before and after the prettier action has ran. Keep this in mind.
