What is the best way to change a flat tire on my Audi?

I just got a flat tire on my Audi and I'm not sure what to do. Can someone please give me step-by-step instructions on how to change it?

First, make sure you have a spare tire, a jack, and a lug wrench in your car at all times. Then, safely pull over to the side of the road and turn on your hazard lights. Loosen the lug nuts on the flat tire before jacking up the car. Once the car is lifted, remove the lug nuts and take off the flat tire. Put on the spare tire and tighten the lug nuts. Finally, lower the car and securely tighten the lug nuts. Be sure to get your flat tire repaired or replaced as soon as possible.
