Connect your Apple TV 4K to your TV with a HDMI cable (you need to buy this separately).
If you use a wired internet connection rather than WiFi, you'll also need an Ethernet cable to connect your router to your Apple 4K box.
Switch it on and follow the onscreen instructions:
- Already have another Apple device – Set Up with Device
- Don't have an Apple device – Set Up Manually
Make sure you have your WiFi username and password – find them on your router.
