+### ⛳ Autostart
+
+You can use [gorge.service](./gorge.service) to integrate gorge into your systemd autostart.
+
+The required steps are:
+
+```bash
+wget https://raw.githubusercontent.com/dadav/gorge/main/gorge.service
+wget https://raw.githubusercontent.com/dadav/gorge/main/defaults.yaml
+sudo mv gorge.service /etc/systemd/system/gorge.service
+sudo mv defaults.yaml /etc/gorge.yaml
+sudo systemctl daemon-reload
+sudo systemctl enable --now gorge.service
+```
+
+If you've installed gorge as a package (rpm, deb, apk), the required files should already be there.
