What is adp-multi?
It is a library based on the original Haskell implementation and can be considered an unoptimized prototype.

Where do I start?
If you don't know the class of multiple context-free languages yet, then you should first read the explanation of them.
After that, you should go to the quick start guide where you learn what's different compared to original Haskell-ADP and how to write your own grammars.
There's also a short motivational/introductional talk called "Predicting Pseudoknots Without Hacking in C" that I gave at the "10. Herbstseminar der Bioinformatik" (2012) which summarizes why adp-multi is useful and in which direction future work might go. Note that the adp-multi syntax in the slides is outdated.
