Explain what you are doing and areas you are having challenges. Throwing off generic questions like this without any serious explanation is the reason many questions are unanswered on this website. We can’t be too lazy at explaining ourselves, being clear where we are heading to.
What have you done so far, what do you intent to do, and what areas are you having challenges? These are reasonable things anyone who wish to volunteer his/her time to answer your questions would like to know.
