    # there are built-in project workflows for assigning new items to a column, and

    # the opened event, and we'll be good to go.

  # this token must have typical repo write access plus full :project access
  # Create this token with the correct permissions and add it as a repo secret
  # It would be preferable to just use the GITHUB_TOKEN that Actions generates for a run,
  # but I can't get the right projects (v2) write access to make it work.  Eventually
  # just use that, set permissions here, and delete the token.
