+* if you register the app into your PeerTube instance (optional), you can retrieve the latest video source instead of the highest quality encoded video
 * it creates a resumable upload into the target YouTube account

 ```
 
 You’ll be then prompted with all the necessary information to register `tootube`. You’ll end with a `refresh_token` that you can now paste inside your tootube configuration.

+If you wish to register `tootube` on PeerTube, you can do so by using:
+
+```bash
+tootube register --peertube --config <PATH TO YOUR TOOTUBE.TOML FILE>
+```
+
+It will require your username/password (beware that 2FA is not supported for this feature as of now) and generate a first `refresh_token` that you will put inside the aformentioned file:
