 ## Features
 
-- Publishes "Hello world" stats every 30 seconds to `system/stats` topic
+- Publishes "Hello from systant" stats every 30 seconds to `system/stats` topic
 - Listens on `system/commands` topic and logs received messages
 - Configurable MQTT connection settings
 - Runs as systemd daemon with auto-restart
