❷ A USB cable to connect the iPod to your computer. The iPod Classic, Nano, and Touch use the same white USB cable with the flat dock-connector port, while the iPod Shuffle has its own little USB dock.
❸ A little pamphlet of basic quick-start information that's not nearly as fun or as colorful as this book.
What you want right now is the USB cable. Connect the small, narrow end to your computer's USB port and the wide, flat end (or the dock, if you have a Shuffle) to the iPod. The first time you connect your iPod to a computer, the Setup Assistant walks you through a few steps to get your iPod ready to go.
The next step, if you want to hear some music, is to get some music on your iPod.
