An example of a good tutorial for the iPhone 5s is the official one on the iPhone Support section on Apple.com. Users can also download quick-start and user guides for different iPhone 5s iOS versions in the Manuals section on the same website.
The main Support section covers information regarding apps, features, accessories and various essentials, including establishing an Internet connection and setting up the iCloud feature. As of 2015, users can also access the introduction to iOS 8 and peruse various tips and tricks for that operating system. The quick-start guide for the iPhone 5s describes the functions of analog buttons, explains how to send messages and how to use the FaceTime feature to establish a video call. The user guide contains nearly 200 pages and 32 chapters that range from the overview to explaining how to add and unify contacts.
