 This repository is the SourceOS distribution surface for Homebrew formulas/casks. It is not a runtime governance authority.
 
+## Formulas
+
+Current SourceOS product-surface formulas include:
+
+- `agent-machine`
+- `bearbrowser`
+- `noetica`
+- `sourceos-devtools`
+- `sourceos-syncd`
+- `turtleterm`
+
+## Noetica service boundary
+
+The Noetica formula installs the workstation CLI and exposes `noetica`.
+
+Homebrew is not the canonical service supervisor for Noetica. Use Noetica's OS-native service adapter commands instead:
+
+```bash
+noetica service install
+noetica service start
+noetica service status
+noetica service stop
+noetica service uninstall
+```
+
+Noetica service mode uses `launchctl` / LaunchAgent on macOS and `systemd --user` or a SourceOS-compatible user service on Linux.
