Gary,
Since you are truly new I will suggest you go thru our tutorial section in the community to answer the majority of your questions. We also have a NRL22 section that is specific.
Start here.

If you post NRL22 questions after you have read a number of the tutorials, Levi, our NRL22 expert will help you.
