Why don't you try yourself? It seems not difficult to complete such a free subject. Suggest you to look up for some documentations you like. Read first, then try to understand and rewrite in your own words, at least change some full sentences by your own words. Don't worry. Take it easy! If you try, you will find you can (do it)!
