How can I properly change the oil in my Audi 80?

I am a new Audi owner and I am not sure how to properly change the oil in my Audi 80. Can someone provide step-by-step instructions or guidance? Thank you in advance.

First, make sure to have all the necessary tools and materials including new oil and filter. Then, locate the oil drain plug underneath the engine, remove it, and let the old oil drain out completely. After that, remove the old filter and replace it with a new one. Finally, refill the engine with the appropriate amount and type of oil. Don't forget to dispose of the old oil properly!
