  # This will use the `labeler.yml` file in the default (master) branch of the repo.

      - ready_for_review

  # The `pull_request` event is used for PRs which change the files which handle the labeling to prevent a silently failing action.
  # This will use the `labeler.yml` file in the PR branch.
