MI steez said it and I'll say it too. When I was learning I used the hand drag method and it worked very well. I stomped it first try. You gotta lean back but forward at the same time. Kind of make a popping position, but squatted (kind of like doing squat jumps) and touching your hand (the one you spin towards) near the tail of your ski on the same side. Make sure to stay strong in the squatting position so you don't get forced all the way back. You'll want a bit more speed because you need to carve. I think it helps if your carve pattern is something like this as it gets you into the 'flow'.
Then you kind of just let your body flow naturally off the jump from this position and you will most likely feel yourself in the position 'against the wall' at 180, at least I did, and then you will come around and land pretty much in line with the landing if it's a good jump.
To progress to non-hand drag, just practice the carve and natural flow off the lip while staying compactish.
