-# Arduino-BLE-MIDI
+# Experimental
-MIDI over Bluetooth Low Energy (BLE-MIDI) 2.0 for Arduino
    
-Depends on [FortySevenEffects/MIDI](https://github.com/FortySevenEffects/arduino_midi_library) 
+# Arduino BLE-MIDI Transport 
+This library implements the BLE-MIDI transport layer for the [FortySevenEffects Arduino MIDI Library](https://github.com/FortySevenEffects/arduino_midi_library) 
 
-# Supported devices
+## Installation
-Adafruit ESP32 Feather
+This library depends on the [Arduino MIDI Library](https://github.com/FortySevenEffects/arduino_midi_library).
+
+When installing this library from the Arduino IDE, the dependency be downloaded and installed in the same directory as this library. (Thanks to the `depends` clause in `library.properties`)
+
+When manually installing this library, you have to manually download [Arduino MIDI Library](https://github.com/FortySevenEffects/arduino_midi_library) from github and install it in the same directory as this library - without this additional install, this library will not be able to compile. 
+
+## Usage
+### Basic / Default
+```cpp
+#include <BLE-MIDI.h>
+#include <hardware/BLE-MIDI_ESP32.h>
+...
+BLEMIDI_CREATE_DEFAULT_ESP32_INSTANCE();
+...
+void setup()
+{
+   MIDI.begin(1);
+...
+void loop()
+{
+   MIDI.read();
+```
+will create a instance named `bleMIDI` and listens to incoming MIDI on channel 1.
+
+## Tested boards/modules
+- Adafruit Huzzah32 feather
+
+## Other Transport protocols:
+The libraries below  the same calling mechanism (API), making it easy to interchange the transport layer.
