| name: Repo Sync | |
| # **What it does**: Syncs docs.getdbt.com public repo into the docs private repo | |
| # This GitHub Actions workflow keeps the `current` branch of those two repos in sync. | |
| # **Why we have it**: To keep the open-source repository up-to-date | |
| # while still having an internal repository for sensitive work. | |
| # For more details, see https://github.com/repo-sync/repo-sync#how-it-works | |
