The `nightly` channel has releases built after each push to the master branch, and will have the most recent fixes and additions, but also have more risk of regressions. They are available in [their own repo](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases).
When using `--update`/`-U`, a release binary will only update to its current channel.
-This release channel can be changed by using the `--update-to` option. `--update-to` can also be used to upgrade or downgrade to specific tags from a channel.
+`--update-to CHANNEL` can be used to switch to a different channel when a newer version is available. `--update-to [CHANNEL@]TAG` can also be used to upgrade or downgrade to specific tags from a channel.
+
+You may also use `--update-to <repository>` (`<owner>/<repository>`) to update to a channel on a completely different repository. Be careful with what repository you are updating to though, there is no verification done for binaries from different repositories.
Example usage:
* `yt-dlp --update-to nightly` change to `nightly` channel and update to its latest release
* `yt-dlp --update-to stable@2023.02.17` upgrade/downgrade to release to `stable` channel tag `2023.02.17`
* `yt-dlp --update-to 2023.01.06` upgrade/downgrade to tag `2023.01.06` if it exists on the current channel
+* `yt-dlp --update-to example/yt-dlp@2023.03.01` upgrade/downgrade to the release from the `example/yt-dlp` repository, tag `2023.03.01`
