+#### Endpoints
+
+The `--xyz-endpoint` options pass directly through to ZeroMQ, so you can use any valid transport string. For example, you could specify `tcp://0.0.0.0:42069` to listen on the network.
+
 ### Sending Frames
 
 The server is a simple ZMQ REQ-REP loop. All you need to do is send your frame as a big ol' byte chunk then wait for an empty message back. Each frame should be in a RGBA32 format.
