+Xbox Controller Pairing Instructions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The first time you use a controller with a hub, you will need to pair
+them: Turn the controller on and then press and hold the pairing
+button on the back of the controller for a few seconds. When you release
+it, the Xbox button starts flashing more rapidly. Then start your program.
+
+When pairing and the connection is succesful, the Xbox button will stop
+flashing and stay on for as long as the program is running.
+
+Repeat Connections
+==================
+
+If you keep using the same controller with the same hub, you can simply
+turn the controller on the next time and the hub will connect to it
+automatically when your program with this class runs.
+
+The Xbox controller only accepts this simpler connection with the most
+recently connected device. So if you connect to your Xbox console again, or
+connect to another hub, you will need to pair them again as described
+above.
+
+Compatible Controllers
+============================
+
+All Xbox controllers released since 2016 are compatible. This includes the
+controller from the One S (``1708`` from 2016), the Elite Series 2 (``1797``
+from 2019), and the Series X/S (``1914`` from 2020), which is
+the latest model as of this writing.
+
+.. raw:: html
+
+  <p>See also <a href="https://en.wikipedia.org/wiki/Xbox_Wireless_Controller#Summary" target="_blank">
+  this overview</a> of model numbers including pictures of each controller.</p>
+
+Updating the Xbox Controller
+============================
+
+If you frequently use the Xbox Controller with your console, your controller
+is probably already up to date. If you have not used it for a while or if you
+bought one recently, you may need to update it.
+
+To update the controller without a console, you can use the Xbox Accessories
+app on a Windows computer. You can download it from the Microsoft Store.
+Connect the controller via USB to the computer and follow the instructions in
+the app to click on "Update now".
+
+Technic Hub Limitations
+=======================
+
+Due to limitations of the Technic Hub, the hub will disconnect from the
+computer when searching for the Xbox controller. This means you will not be
+able to see output from the ``print`` command. Also, you'll have to connect to
+the computer again if you want to change your program.
