 ## Production
 
-please set the environment variable for production use:
+I'm using [pm2](https://www.npmjs.com/package/pm2) on my production system to start jsSauna.
 
-```sh
-NODE_ENV="production" jsSauna --rp 14 --sp 4
-```
+Make sure you install jsSauna with all optional dependencies!
+Otherwise you will use **testdata** for the sensors and On / Off requests will be **ignored** for the relay!
+
+### Troubleshooting
+
+If you have problems installing jsSauna globally as root using `sudo npm i -g jssauna`, you can try the option `--unsafe-perm`.
