I want to be a DJ? Ways to become one?

I am very interested in becoming a DJ. I don't know HOW to DJ though
so first I want to get that out of the way. I'm 16. So if anyone can
send some links my way or tell me where to go to learn, that'd be much
appreciated.

And secondly, how can I begin to DJ at clubs and become well known?
You dont have to go to college for DJing right? XD

Thank you. :)
