+In this project we'll show you how to control the Audi RS Q e-tron with the
+Xbox Controller, using either block programming or Python.
+
+Be sure to check out the documentation in the Pybricks app for instructions
+to pair the controller with the hub.
+
+Note: This is brand a new feature. Try it with [Pybricks beta](https://beta.pybricks.com/)!
+
+# Block Program
+
+You can easily code this with the new block coding feature. Just drag and drop
+the blocks as shown below, or download the ready-made project here. In
+Pybricks, just go to the file menu and click the "Import a file" icon to open
+it.
