Amazon has been playing with the idea of delivering packages via drone for a few years now, but in a video released Sunday the company revealed more details about how the delivery system will work.

The video, narrated by Top Gear’s Jeremy Clarkson, features actual footage of an Amazon drone in flight and explains just how Amazon Prime Air will work.

Shoppers will be able to select a delivery time of 30 minutes or less when placing an order. The purchased item will then be stowed in the drone, which rises 400 feet in the air before heading towards its destination. Shoppers will get an alert when their package is nearby, and once the drone arrives at its destination it scans for a safe spot to land. A hatch at the bottom of the drone then opens to drop off the package. 

There is no official word about when Amazon Prime Air will be ready for take off.
