Steam Guides Available Now

Browse and create user-made walkthroughs and tips on Steam
Valve has announced the launch of Steam Guides, a new capability of the Steam platform that allows players to create and/or find guides for their favorite games or software titles on Steam.
Steam Guides lets players create and share guides, walkthroughs, and tips for their favorite games or software to help others who might be stuck or who simply want to learn more about the game. Players may easily create guides through Steam, where they may upload images, add screenshots, and embed YouTube videos. Guides are then quickly accessible through Steam, via the Steam Community and in-game via the Steam Overlay.
