How do I use the self parking feature on my Audi A7?

I have recently purchased an Audi A7 and I am not sure how to use the self parking feature. Can anyone provide step by step instructions?

To use the self parking feature on your Audi A7, first make sure the feature is activated by pressing the parking assist button on the center console. Then, while driving at a slow speed, look for a parking spot on the instrument cluster display and select the appropriate size of the spot. Release the steering wheel and control pedals and follow the instructions on the display to let the car park itself.
