Bluetooth is a wireless protocol that allows you to connect many different types of devices to your computer. Bluetooth is commonly used for headsets and input devices like mice and keyboards. You can also use Bluetooth to send files between devices, such as from your computer to your cell phone.
Things to improve: The BT settings has a "Browse Files" button for devices. We only cover push file transfers. Might also be worth mentioning something on receiving files when doing push from another device.
We don't have explicit pages for input devices. Might be worth a topic like "Connect a BT mouse or keyboard", linked under Mouse, Keyboard, and BT.
We have nothing for BT printers. Topic under both Printing and BT. Consider other device classes, topics linked under both BT and the appropriate device-specific guide (e.g. headset under Audio).
A topic on Bluetooth security would be good. Might want to also create a new top-level guide for security, and link the topic there too.
