| # This workflow keeps the repo up to date with changes from the template repo (REMOTE_URL) | |
| # It duplicates the REMOTE_BRANCH (into UPDATE_BRANCH) and tries to merge it into the | |
| # this repos default branch (which is checked out here) | |
| # Note that this requires a PAT (Personal Access Token) - at best from a servicing account | |
| # Also note that you should have at least once merged the template repo into the current repo manually | |
| # otherwise a "refusing to merge unrelated histories" error might occur. | |
