How do I change the windshield wipers on an Audi A1?

I have an Audi A1 and I noticed my windshield wipers are not working properly. How can I change them myself without damaging anything?

First, make sure to purchase the correct size windshield wipers for your Audi A1. Next, lift the wiper arm away from the windshield and press the small tab on the underside of the wiper blade. While holding the tab, slide the blade down and away from the arm. Then, attach the new blade by sliding it onto the wiper arm until you hear a click. Finally, gently lower the arm back onto the windshield. Remember to replace your wipers regularly for optimal performance.
