I am currently doing a project on Furi. I am supposed to figure about how Furi works. And more than just figuring out the architecture, I have to suggest some ways to improve Furi. I have download the source code of Furi, but as you all know, reading source code is a quite hard work, so could anyone one give me some documentation on how Furi was designed? (Classes used, what functions performed by each class, relations between classes, any assumptions made, any unique way of solving some issues, whatever)

Thanks a lot. Please do help me.
