+# flipnoise.py
+#
+# Converts Renoise song files (.xrns) to Flipper Zero song files (.fmf). Pass
+# in the .xrns file as the only argument and flipnoise will unzip it, parse
+# the Song.xml file within and generate a .fmf file you can place on your
+# device with qFlipper.
+#
+# flipnoise will read the song name, artist name and BPM from the Renoise file.
+# Empty lines are filled in with the last note played. The intention here is to
+# primarily make chiptune/keygen-sounding music at a very high BPM (e.g., 500).
+#
+# Note that Flipper Zero only has a single sound channel, so only make one track
+# in your Renoise song.
