Start by finding the power and HDMI leads in the box. Use the HDMI cable to connect the Xbox to your TV, and plug in the mains power lead.
If the Xbox is close enough to your router, use an ethernet cable to connect them together for the best results. You could use Wi-Fi instead, but a wired connection helps to reduce latency (the time taken for your Xbox to send data to and from a game server) to give the best experience.
When you turn your Xbox One on for the first time you'll see the 'Setup Wizard', which will help you get the console ready to use. Press the Xbox button on the front of the console to turn it on, then do the same with the controller.
Use the D-pad (or direction pad - the cross-shaped button on the left) Xbox controller to highlight and change settings, press the 'A' button to pick an option and move forward, and press the 'B' button to go back to a previous screen. Just remember that some screens won't give you the option to go back.
Pick the language to use on your Xbox then press A.

When you've connected, press A to move on. If something went wrong, try to connect again.
