You can easily find a couple of videos on google or yahoo or bing.com. I’d advise you to go see a video on how to do it, or ask a friend to show and teach you in person how to do it. It’s hard to explain in words, especially about the fact that everyone has a different style, like some people have their feet position differently. It’s like asking how to write with a pencil: there’s no wrong way (most of the time), but you have to be able to do it. Just google ‘how to ollie’ or ‘how to ollie on a skateboard’ and go to videos. I notice you asked this 9 months ago, so you probably already figured out how to do it. In that case… my bad.
