Apple only includes a “Getting Started” guide with your Apple products. Why? Because the software is constantly changing and a printed manual would soon be out of date. Instead, they offer free electronic manuals in the iBook bookstore.
Last week Apple released iOS 9.3 along with new electronic manuals. If you already had the iOS 9 manuals a revision should be available. Or you can use the links below to download them below on your Mac, iPhone, or iPad for free.
