+Check out a [sample workflow](https://github.com/net-engine/github-repository-sync-action/blob/master/.github/workflows/test.yml).
+
 Inspired by the following actions
 
 * [wei/git-sync](https://github.com/wei/git-sync)
 * [pixta-dev/repository-mirroring-action](https://github.com/pixta-dev/repository-mirroring-action)

+uses: netengine/github-repository-sync-action
 with:
   who-to-greet: 'Mona the Octocat'
 
 ## TODO
 
-* Support for any branch, similar to [actions/checkout@v2](https://github.com/actions/checkout)
+* Support for any to and from branch, similar to [actions/checkout@v2](https://github.com/actions/checkout)
+* Make SSH key-based authentication optional to support username/password authentication
