Exactly what ^^^ said, you go the long way (Through options and all that) then instead of entering your username and password, there should be a button or link to create a new account. It WONT overwright your previous one if you have one so its safe too.
If you need further tips, this is a simple process and almost everyone on here knows how to do it so just ask anyone if you get stuck.
