okay.....firstly the most important thing about skateboarding.....practice practice practice practice practice practice and PRACTICE!!!
okay now how to ollie
1. place your back foot on the tail of the board with about a quorter of your shoe hanging off the back.
2. place your front foot just before the bottom bolts on the NOSE of your deck
3. crouch down but try to bend your knees not your back
4. snap the tail AS HARD AS YOU CAN!
5. at the same time slide your front foot up and jump
this is one of the hardest tricks considering you don't know anything but once you get it you will learn alot fast!
practice on carpet(if allowed) if not practice on grass outside!
another way to do it is hold on to somthing like a hand rail and try to ollie it should help!
more or less from that all you can do is practice until you get it!
do you think Tony Hawk, Rodney Mullen, Chris Cole or Jamie Thomas got an ollie their first try? of course not they practiced and if you practice you could be as good as them!

Happy Sk8in ;D
