Is there a more concise tutorial/documentation?

[waosp]

Just tell me how to split received encrypted text/MAC/message/g/etc.
And tell me how to make adapted encrypted text/MAC/message/g/etc.
Base on the unencrypted plaintext rather than account/JID/context??
use received message and send message finish "otr start"/"otr end"/"otr generate"/decrypt message/encrypt message?
And the documentations in the issue:#33 is entirely useless(404 Page not found/OTR official introduction,this documentation didn't tell me more things about this).
