How do I change the windshield wipers on my Audi A6?

I am having difficulty figuring out how to change the wiper blades on my Audi A6. Can anyone walk me through the process?

First, lift the wiper arm away from the windshield and locate the small tab on the underside of the wiper blade. Press this tab to release the old blade and slide it off the wiper arm.

Next, line up the new wiper blade with the arm and push it until it clicks into place. Then, carefully lower the arm back onto the windshield.
