+### As a managed daemon (with procd)
+
+`procd` is the init system on OpenWRT. If you want to use godns as a service with OpenWRT and procd:
+1. Copy `./config/procd/godns` to `/etc/init.d` (and tweak it to your needs)
+2. Start the service (with root privilege):
+
+   ```bash
+   service godns enable
+   service godns start
+   ```

 ### As a Docker container
