-inputs' states. A complete state packet might look like:
-
-```
-02 00 00 00 00 00 00 01

-
-Bytes arrive in that order, left to right. The least-significant bit (LSB) of
-each byte is reserved; only the top 7 bits of each byte represent Arduino
-inputs, with 1 for "button down" and 0 for "button up". A byte with the LSB set
-is an end-of-message indicator, meaning you can append it to the last 7 bytes
-you received and start decoding the full bitfield.
-
-Each Arduino can serve around 50 buttons. The 100-button board uses two Arduinos
-that appear as separate serial ports. This server treats each as a separate,
-numbered device with its own buttons.

-## Upsides of a Web API
-
-- Every development platform and language has a way of talking to the web, so
-  this opens up the 1000 Buttons hardware to lots of potential users.
-- The server's not that complex, so it should scale well. Y'know, probably. If
-  not, there's room to optimize.
-- I got to play with neato Javascript features like async/await, generators, and
-  iterables when I was implementing the server.
-
-## Downsides of a Web API
-
-- Polling latency if you're not using WebSockets. You can poll pretty fast, but
-  you can't possibly poll ths server fast enough for a fighting game to feel
-  good. Definitely use WebSockets if you can. If not, maybe there are other
-  kinds of games you could make?

 ## WebSocket events
 
 The WebSocket address is `ws://localhost:3000/`.
