I think you should describe what has been done so far and where you got stuck. It's unlikely anyone is going to help you if you write such a general post, most people won't take the time to dig through the repo.

In particular, I could take a look at your problem, maybe I'd have an idea. In my life I had a lot of situations where people struggle for a long time, then ask someone else to overtake it, the other guy gets instant progress, gets stuck, asks someone else to take a look and work a while, and this third person gets instant progress, etc.
