          # For work-in-progress PRs you can typically use draft pull requests
          # from Github. However, private repositories on the free plan don't have
          # this option and therefore this action allows you to opt-in to using the
          # special "[WIP]" prefix to indicate this state. This will avoid the
          # validation of the PR title and the pull request checks remain pending.

          # When using "Squash and merge" on a PR with only one commit, GitHub
          # will suggest using that commit message instead of the PR title for the
          # merge commit, and it's easy to commit this by mistake. Enable this option
          # to also validate the commit message for one commit PRs.

          # to use the `labeled` and `unlabeled` event triggers in your workflow.
