PlayStation Knowledge Center
The PS Vita ships with a paper Quick Start Guide that provides basic information on the functions of the PS Vita. More-detailed operating instructions can be found online in the PS Vita User's Guide, located at:
This online user's guide is constantly updated and provides detailed information on operating the PS Vita, instructions on how to access and change various settings, and gives an in-depth look into the PS Vita's many applications.
Note: PS Vita games do not ship with traditional paper instruction manuals. All game manuals are built-in to the games themselves. Game manuals are accessed by tapping the game's application bubble and then the "book with a question mark" icon at the top of the game's Live Area.
