There is no comprehensive tutorials on it yet, the best bet is to look up anything to do with THN's (there was a tutorials about understanding THN's a long while back). It is possible to do, but it requires far more coding than a simple INI file. My warning is do not attempt unless you have the time, patience and hair left for it
I know Argh at some point was considering making a tutorial on this all, as have I. Perhaps in the future myself and Argh might compile both our stored knowledge on this subject and create a comprehensive tutorial for everyone, but the question is time, as not only is editting THN's costly in time, but to write a tutorial that fully explains it will also require a large amount of time.
