name: Update from Template | |
# 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. | |
