First become very comfortable with fakie rocks, you will most likely benefit from learning blunt to fakie rocks also, with that being said lets get started. Approach the lip with just enough speed to get your back wheels over the coping. It's very important that you don't try an hang out on the coping, quick is the way to go you'll need that momentum and balance to successfully roll away with this one. As your tail becomes attached to the coping you want to begin to compress your back knee just a little bit to get some leverage, while keeping your body weight inside the ramp at all times, apply the same technique you use when your trying to ollie on the carpet with just a deck, pop that sucker back in keeping your front foot a little curled to keep the board on your feet, land in the ramp fakie touching down with your back wheels just a moment before you set down your front, this is so you don't have to pop entirely in and don't have to worry about locking your front truck on the down. This is a difficult and sometimes painful trick to learn, stay confident and calm and you should be alright.
