How do I change the engine oil in an Audi 80?

I recently bought an Audi 80 and I want to learn how to change the engine oil myself. Can someone provide me with step-by-step instructions?

First, gather all necessary tools such as a wrench, jack, and oil pan. Then, locate the oil drain plug and unscrew it to drain the old oil. Next, unscrew the oil filter and replace it with a new one. Finally, refill the engine with new oil according to the recommended amount for your Audi 80 model.
