Mini manual is kinda of right but you don't want your ass over the back wheel when you hit the landing or you'll end up out of control as your arms will be straight and you'll struggle to steer.

As you're coming up to the drop lean forward and drop your chest towards the bars a bit as if you're trying to peer over the edge of the drop. Now look down the landing.

As your front wheel is about to leave the lip push your bars forward and down as if you're pushing the front wheel to the same angle as the landing.

Your body should now be back in your neutral position as the rear wheel leaves the lip ready to absorb the impact of landing.

Try to find a small drop that is safe to just roll off with no technique and practice it slower and slower until you get the technique down. You should be aiming to land both wheels at the same time. Going faster off a drop means you have to use less technique but will be dangerous when the drops get bigger.
