 ## Notifications
 
-The script sends success or failure notifications via Gotify.
+The script can send success or failure notifications via Gotify when enabled. To enable notifications, set `ENABLE_GOTIFY=true` and provide the required Gotify configuration variables (`GOTIFYHOST`, `GOTIFYTOKEN`, `GOTIFYTOPIC`). When notifications are disabled, backup status messages are still logged to the console.
 
 Example success notification:
 
 ```
 Backup successful. Snapshot 56ff6a909a44e01f67d2d88f9a76aa713d437809d7ed14a2361e28893f38befb: files new: 1, files changed: 0, data added: 1019 bytes in 0.277535184 sec
 ```
+
+When Gotify is disabled, you'll see a single message at startup indicating notifications are disabled, followed by normal backup status messages:
+
+```
