+## Release Channels
+
+The public Homebrew cask tracks stable desktop releases:
+
+```bash
+brew install --cask stablyai/orca/orca
+```
+
+Release candidates use a separate cask token:
+
+```bash
+brew install --cask stablyai/orca/orca@rc
+```

+normal `brew uninstall --cask` followed by the install for the other channel.
+Do not use `--zap` unless you intentionally want to remove local Orca state.
