| # The docs.github.com project has two repositories: github/docs (public) and github/docs-internal (private) | |
| # | |
| # This GitHub Actions workflow keeps the `main` branch of those two repos in sync. | |
| # | |
| # For more details, see https://github.com/repo-sync/repo-sync#how-it-works | |
| name: Repo Sync | |
| # **What it does**: | |
| # - close-invalid-repo-sync: Close repo sync pull requests not created by Octomerger or a Hubber. | |
| # - repo-sync: Syncs docs and docs-internal. | |
| # **Why we have it**: | |
| # - close-invalid-repo-sync: Another form of spam prevention for the open-source repository. | |
| # - repo-sync: To keep the open-source repository up-to-date, while still having an internal | |
| # repository for sensitive work. | |
| # **Who does it impact**: Open-source. | |
