If you’re one of the lucky developers or quick-click buyers who have an Apple Watch arriving on April 24, then you’ll take particular interest in knowing that the user guide for the first Apple device from a new product category in 5 years is online right now.

While you’re waiting for your precious new watch to arrive, you can familiarize yourself with some of its features and learn some of its more minute functions. For those who still haven’t placed an order or perhaps are unsure as to whether they should, this guide could serve as the most detailed glance you’ll get into the Apple Watch and its day to day functionality without actually buying one first.

The user guide offers an in-depth look at the interface of the watch. It outlines all the different functions, explains which button performs which action, and details how to care for the device. It teaches you how set up Apple Pay, customize your watch face, and really familiarize yourself with its unique touch interface.

There are quite a few neat features hidden in this guide, including a list of functions the Apple Watch can manage without a connection to your iPhone. Contrary to popular belief, you will be able to track workouts on it without your iPhone nearby. The guide also mentions the handy “iPhone Ping” feature, which will make your iPhone ring until you find it buried in some bizarre place. The full guide should help answer many of your Apple Watch curiosities. You can read through it on Apple’s site.

The Apple Watch goes on sale tomorrow, but it will not be available in stores during the start of the official launch period. So if you’re interested in the Apple Watch, you’d better get online because the current estimated shipping for preorders is 4-6 weeks.
