-Watchdog has default values for all thresholds which fit great for most of setups.
+Watchdog uses default values for all thresholds defined in `docker-compose.yml`.
 
-Thresholds variables don't added to `mailcow.conf` by default.
+The default values will work for most setups.
-To adjust them just add needed threshold variable to `mailcow.conf` and run `docker-compose up -d`.
+
+Example:
+
+```
+       - NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
+        - UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}
+        - REDIS_THRESHOLD=${REDIS_THRESHOLD:-5}
+        - MYSQL_THRESHOLD=${MYSQL_THRESHOLD:-5}
+        - MYSQL_REPLICATION_THRESHOLD=${MYSQL_REPLICATION_THRESHOLD:-1}
+        - SOGO_THRESHOLD=${SOGO_THRESHOLD:-3}
+        - POSTFIX_THRESHOLD=${POSTFIX_THRESHOLD:-8}
+        - CLAMD_THRESHOLD=${CLAMD_THRESHOLD:-15}
+        - DOVECOT_THRESHOLD=${DOVECOT_THRESHOLD:-12}
+        - DOVECOT_REPL_THRESHOLD=${DOVECOT_REPL_THRESHOLD:-20}
+        - PHPFPM_THRESHOLD=${PHPFPM_THRESHOLD:-5}
+        - RATELIMIT_THRESHOLD=${RATELIMIT_THRESHOLD:-1}
+        - FAIL2BAN_THRESHOLD=${FAIL2BAN_THRESHOLD:-1}
+        - ACME_THRESHOLD=${ACME_THRESHOLD:-1}
+        - RSPAMD_THRESHOLD=${RSPAMD_THRESHOLD:-5}
+        - OLEFY_THRESHOLD=${OLEFY_THRESHOLD:-5}
+        - MAILQ_THRESHOLD=${MAILQ_THRESHOLD:-20}
+        - MAILQ_CRIT=${MAILQ_CRIT:-30}
+```
+
+
+To adjust them just add necessary threshold variables (e.g. `MAILQ_THRESHOLD=10`) to `mailcow.conf` and run `docker-compose up -d`.
