+This library supports a few additional features that the Mouse library does not support at the time of writing:
 
 - Scrolling left/right E.g.: `bleMouse.move(0,0,0,1)` (Scroll left) and `bleMouse.move(0,0,0,-1)` (Scroll right)
 - Using the back and forward buttons E.g.: `bleMouse.click(MOUSE_BACK)` and `bleMouse.click(MOUSE_FORWARD)`
 
+There is also Bluetooth specific information that you can use (optional):
+
+Instead of `BleMouse bleMouse;` you can do `BleMouse bleMouse("Bluetooth Device Name", "Bluetooth Device Manufacturer", 100);`.
+The third parameter is the initial battery level of your device. To adjust the battery level later on you can simply call e.g.  `bleMouse.setBatteryLevel(50)` (set battery level to 50%).
+By default the battery level will be set to 100%, the device name will be `ESP32 Bluetooth Mouse` and the manufacturer will be `Espressif`.
