 .. note::
     Over the lifetime of Open edX, we may fork the same external open source repository multiple times.  In this case, we may need to archive the fork multiple times as we move between our fork and following upstream.  When this is necessary, if possible un-archive the old fork and update it.  If you've already made a new fork, delete the old copy of the fork before you move the new repo to openedx-unsupported.
