How can I change the air filter on my Audi A4?

I just bought an Audi A4 and I noticed that the air filter looks dirty. How can I change it myself? Is it difficult or should I take it to a mechanic?

Replacing your air filter regularly is important for the performance of your car. I suggest doing it every 10,000 to 15,000 miles. But it also depends on your driving conditions. Let me explain further.
