     * Merging a PR will update the positions of all PRs in the queue.
     * Adding the `JUMP THE QUEUE` label to a PR will make that PR first in the queue immediately.
-  * This helper can be used to build a fully automated merge queue when used in conjunction with `prepare-queued-pr-for-merge`.

 ### [**move-project-card**](.github/workflows/move-project-card.yml)
 * Moves a GitHub Project card to a new column, using the `project_origin_column_name` and`project_destination_column_name` you provide.
 * In order to move a card from one place to another, it must already exist.
