I don't want to be mean, but have you ever played a video game before? I find it incredibly weird that someone, especially on GAF, can have a game for a week and not understand how to play.
Two attack buttons, modify attacks by inputting direction, jump, defend. You die when you fall off stage, the more damage you have, the farther you fly when you get hit. These are the basics, you can pick them up in one match, the rest you learn by playing.
Then there's a tutorial video, a manual and the Internet. I understand that the game is a bit different and chaotic, but it's not that hard to follow, hell, you can even play 1 on 1 on a simple level and disable items to get the hang of it.
