Check out my tutorial on backside flip, its just the opposite of this.
But Anyway here we go.
1st. Put your fingers with your middle finger on the tail and your pointer in the middle of your board
2nd. Push the board out with a spinning motion with your middle middle finger.
2nd 1/2. When the board gets halfway around, flick the nose like you would with a kickflip
3rd Watch the grip tape come around and then catch it.
Tips-
When the board flips out of control its means your flicking to early!
