 ### WebSocket
 
-Coming soon!
+The CircuitPython serial interactions are available over a WebSocket. A WebSocket begins as a
+special HTTP request that gets upgraded to a WebSocket. Authentication happens before upgrading.
+
+WebSockets are *not* bare sockets once upgraded. Instead they have their own framing format for data.
+CircuitPython can handle PING and CLOSE opcodes. All others are treated as TEXT. Data to
+CircuitPython is expected to be masked UTF-8, as the spec requires. Data from CircuitPython to the
+client is unmasked. It is also unbuffered so the client will get a variety of frame sizes.
+
+Only one WebSocket at a time is supported.
