+## Development
+
+The development of the supervisor is a bit tricky. Not difficult but tricky.
+
+- You can use the builder to build your supervisor: https://github.com/home-assistant/hassio-build/tree/master/builder
+- Go into a HassOS device or VM and pull your supervisor.
+- Set the developer modus on updater.json
+- Tag it as homeassistant/xy-hassio-supervisor:latest
+- Restart the service like systemctl restart hassos-supervisor | journalctl -fu hassos-supervisor
+- Test your changes
+
+Small Bugfix or improvements, make a PR. Significant change makes first an RFC.
