+# About
+
+This is code to control the lights of the Butterfly of https://www.facebook.com/TPATB2019
+
+A Raspberry Pi (see that folder's readme for more) hosts and control server, renders frames,
+and pushes those frames to connected devices.
+
+Connected Arduinos (well, technically, the Butterfly uses Teensyduinos) then push the frames
+to the LEDs.
+
+The server code is in Ruby.
+
+# Setup
+
+You will need Git LFS: https://git-lfs.github.com/ - *before* you clone the repo.
+You will need Ruby (and Bundler). RVM is recommended.
+

+Instructions and files for setting up the hardware should go into the corresponding folders.

+`server/lib/compositions` contains preset patterns. Please add more!
+`server/lib/serial` contains the code for pushing data to the Arduinos over serial connections (currently USB serial)
