Apple has today posted its Apple Watch User Guide, as customers begin to receive their Watches starting tomorrow. The guide serves as an accompaniment to the Watch, teaching users how to navigate around the interface and access various features. The guide covers all of the native first-party Apple Watch apps as well as general user-interface tips and tricks.
There is also a section on pairing the Watch, which will prove useful when Watches start being distributed into customers hands from tomorrow morning. There is also information about how to properly take care and clean the Apple Watch bands.
