How does the Audi e-Tron handle regenerative braking?

I've heard that the Audi e-Tron has regenerative braking, but I'm not sure how it works. Can someone explain it to me?

Regenerative braking in the Audi e-Tron is activated when you release your foot off the accelerator pedal. It uses the electric motors to slow down the car and converts that kinetic energy into electricity that is stored in the battery. This helps to improve the car's range and efficiency.
