A very simple explanation. This assumes the wind is coming from your left while you are standing at the pilot station facing the runway.
1.) Taxi to the end of the runway to your right,
2.) Takeoff and fly straight out for a few seconds to gain altitude (upwind leg),
Ummm, just a nit, but for those who follow directions to the letter, you might want to add "and turn around" to the end of step 1. If they overlook this omitted, but obvious (to most) step, their pattern will be all messed up (if they can even get off the ground from the end of the runway).
