To connect a wireless mouse that uses a USB dongle, it's as simple as plugging the dongle into your computer and then turning on the wireless mouse. Most likely your computer will automatically download any firmware required and then you’re off to the races.  If you want to connect your wireless mouse via Bluetooth, first ensure that both your mouse and computer are Bluetooth compatible and it's enabled. Then find your device settings on your computer and press and hold the synchronization button on the wireless mouse. It should pop up on the list of available Bluetooth devices on your computer. Simply click to connect and you’re good to go.
