| # Check for the presence of a PROJEN_GITHUB_TOKEN secret. | |
| # | |
| # This is expected to contain a personal access token of someone who has | |
| # permissions to bypass branch protection rules. | |
| # | |
| # If not present, we can only use GitHub Actions Token permissions, | |
| # but this has the following downsides: | |
| # | |
| # - Those are bound by branch protection rules (so automated pushing won't work). | |
| # - As soon as a workflow file needs to be changed, GitHub will reject the push. | |
| # Only Apps and Users can be allowed to modify workflows. | |
