+// This sketch is for building a simple MIDI controller with 2 buttons for
+//  sending note values & 2 knobs for control values
+//
+// To get this working, you should have set up the following hardware:
+//  - a switch from Digital Pin 2 to +5v, and a 1 to 10K resistor from 
+//      pin 2 to ground
+//  - a switch from Digital Pin 3 to +5v, and a 1 to 10K resistor from
+//      pin 3 to ground
+//  - a potentiometer with one side at +5v, one side at ground, and the
+//      wiper (center pin) connected to Analog Pin 0
+//  - a potentiometer with one side at +5v, one side at ground, and the
+//      wiper (center pin) connected to Analog Pin 1
+//
+
+#include "Midi.h"
+
+// Create an instance of the Midi class.
+//
+// If we were had to receive messages, you'd have to make a subclass of the
+//  Midi class.  See the MidiReceiveExample for an example of how to do that.
+//
+// Sending is a lot easier :)
