Here's a 'clue' as to what you need to do to get the job done. Since I don't want to assume you're installing sheet or tiles, I'll 'point' you to the Starting Page and you can pick which 'style' you're installing.
DO read everything a couple of times or 3 so you have more than a clue as to what you need to do. Vinly Floors is where you start. If you have any more ?'s, you know where to find us.
