+# MIDI converter
+
+  Included in the utils/midi directory is a my first version of a MIDI
+  to NES music converter, which is composed of a Ruby script backed
+  by a C++ program I wrote to parse MIDI files into YAML data.
+
+  At present, it can convert a MIDI file to a binary stream of values
+  that, when written to the APU in your 60hz VBlank, can be played
+  by the included sound driver code.
+
+  The idea is to be able to compose music for the NES using your 
+  favourite digital audio workstation in MIDI, and be able to convert
+  the square, triangle, and noise sequences to something playable
+  on the NES.
