Asking how to read the code is a non-sensible question. Its like asking how do you speak French. The answer is, I speak it. You don't know how to speak it? Well staring at incomrehesible code aint helping you any. It requires one to interact with it, and that requires background. So the question is, I just do and if I can't understand it I roll up my sleeves and research, ask, discuss, and work with it.
