How to properly change the engine oil in an Audi A4?

I'm planning to change the engine oil in my Audi A4. Can someone give me a step by step guide on how to do it properly?

Start by warming up the engine to make the oil more fluid. Then, locate the oil drain plug and remove it to drain the old oil. Let it drain completely before reinstalling the plug. Next, remove the oil filter and replace it with a new one. Finally, add the appropriate amount of new oil and check the level with the dipstick.

Before starting, make sure to have all the necessary tools and materials such as oil, oil filter, wrench, and oil pan. As for the process, begin by draining the old oil from the oil drain plug. Then, replace the oil filter and pour in the new oil. Don't forget to check the oil level and clean up any spills.
