 Watchdog uses default values for all thresholds defined in `docker-compose.yml`.
 
 The default values will work for most setups.

 Example:
-
 ```
-       - NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
+- NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
-        - UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}

 To adjust them just add necessary threshold variables (e.g. `MAILQ_THRESHOLD=10`) to `mailcow.conf` and run `docker-compose up -d`.
