| # This workflow runs on a schedule | |
| # It finds all the PR owned by neurobagel | |
| # that have the _community labels applied. | |
| # It then checks if the PR has already been added to | |
| # the main project and adds the PR if it hasn't been added yet. | |
| # Finally the workflow moves the PR to the "Community" column | |
| # on the project board. | |
