What is Audi A7 virtual cockpit and how does it work?

I've heard about the Audi A7's virtual cockpit, but I'm not sure what it does or how to use it. Can someone explain it to me?

The Audi A7's virtual cockpit is a digital display that replaces traditional analog gauges. It can be customized to show different information such as speed, navigation, and infotainment. To use it, simply use the controls on your steering wheel to navigate through the displays.
