There is not a basics section per se. All you need to do is go to the appropriate forum and ask your questions. They will need to be more specific than this one.
Not sure of which forum? Look at the titles of the forums and put your question where you think it belongs. We'll move it if it needs to be moved, but don't rely upon that for getting it in the right place.
If you have a specific question and not sure where to place it, put it in the Off Topics forum or ask a mod.
