I have heard that it is possible to control my Apple TV using my Apple Watch! This sounds great. How is it done?

You can use the default Remote app on your Watch to control your viewing and your music. Launch the app and then – ensuring that your Watch and Apple TV are on the same Wi-fi network – tap ‘Add Device’. A pairing number should now appear. Now turn to your Apple TV and go to Settings>remotes and Devices>remote App and Devices and then select your Watch and enter the pairing code to link them together.
