How we write our guides

  • Practical steps

    Instructions follow the buttons and menus you will actually see, with notes where wording differs between devices.

  • Safety first

    Every guide explains how to check where a code leads before you open it, and what to do if something looks wrong.

  • Honest about limits

    We say plainly what a browser can and cannot do, such as joining Wi-Fi for you or reading barcodes that are not QR codes.
