-There are currently two release channels for binaries, `stable` and `nightly`.
-`stable` is the default channel, and many of its changes have been tested by users of the nightly channel.
-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).
+There are currently three release channels for binaries: `stable`, `nightly` and `master`.
+
+* `stable` is the default channel, and many of its changes have been tested by users of the `nightly` and `master` channels.
+* The `nightly` channel has releases scheduled to build every day around midnight UTC, for a snapshot of the project's new patches and changes. This is the **recommended channel for regular users** of yt-dlp. The `nightly` releases are available from [yt-dlp/yt-dlp-nightly-builds](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases) or as development releases of the `yt-dlp` PyPI package (which can be installed with pip's `--pre` flag).
+* The `master` channel features releases that are built after each push to the master branch, and these will have the very latest fixes and additions, but may also be more prone to regressions. They are available from [yt-dlp/yt-dlp-master-builds](https://github.com/yt-dlp/yt-dlp-master-builds/releases).
 
 When using `--update`/`-U`, a release binary will only update to its current 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`
+* `yt-dlp --update-to master` switch to the `master` channel and update to its latest release
+* `yt-dlp --update-to stable@2023.07.06` upgrade/downgrade to release to `stable` channel tag `2023.07.06`
+* `yt-dlp --update-to 2023.10.07` upgrade/downgrade to tag `2023.10.07` if it exists on the current channel
+* `yt-dlp --update-to example/yt-dlp@2023.09.24` upgrade/downgrade to the release from the `example/yt-dlp` repository, tag `2023.09.24`
+
+**Important**: Any user experiencing an issue with the `stable` release should install or update to the `nightly` release before submitting a bug report:
+```
+# To update to nightly from stable executable/binary:
+yt-dlp --update-to nightly
+
+# To install nightly with pip:
+python -m pip install -U --pre yt-dlp
