Flight to altitude. Instructors ask you if you are ready to skydive, and wait for you to shout YES! Door opens, you stand/kneel on the edge, one outside and one inside holding your jump suit straps.
Basically they grab you and throw you out of the plane as most won't jump on their first go. After that its a few practice pulls, altitude awareness, following hand signals, and waving and pulling at 5500 foot after watching the altimeter spinning back. Land your parachute following commands hopefully from you instructor when he lands before you.
