Yep, though it's one of the parts of Twisted that only has API documentation and a few examples, no expository prose-style docs. If you're feeling brave, though: http://twistedmatrix.com/documents/current/api/twisted.conch.insults.insults.ITerminalTransport.html http://twistedmatrix.com/documents/current/api/twisted.conch.insults.insults.ITerminalProtocol.html http://twistedmatrix.com/projects/conch/documentation/examples/ (the insults section) It's not really all that complicated, but without adequate docs it can still be tricky to figure things out. There's almost always someone on IRC (#twisted on freenode) to offer real-time help, though.
