It's an AT&T version, but for the most part it has everything you need for a Verizon user... I've tried to find a Verizon version, but they have not made it available online as far as I can find yet.
When you open the Galaxy S4 main forum (not the carrier specific forums) you'll see several Sticky threads before the usual discussion threads. The fourth one in the list is Samsung Galaxy S4 Full User Manual (PDF) Download.
If you are on Verizon, the Verizon manual is on page 2.
