-# BLE GATT HRM Service
+# Sleep as Android Integration
 
-Adds the GATT HRM Service to advertise the current HRM over Bluetooth.
+This app provides support for Sleep as Android using Gadgetbridge.
 
 ## Usage
 
 This boot code runs in the background and has no user interface.
+For this to work you have to enable Sleep as Android support in Gadgetbridge and
+select your Banglejs device.
+
+**Please Note**: This app does not activate the HRM sensor. It only listens to HRM events.
+You may want to adjust the HRM sampling rate in the Health APP. I recommend at least one sample 
+every 10 minutes.
