Valve has released Steam Family Sharing to all users. The feature first launched in beta September of last year and allows you to share your game library with up to 5 friends.
After you add players to your Family Sharing group, you can request access to a friend’s game. Only one of you can play at a time, though the owner of the game will have access at all times. The guest will be given the option to buy the game or to quit playing
To enable Family Sharing, you’ll have to ste up Steam Guard if you haven’t already. Go to Steam > Settings > Family to authorize your computer to share with users. You and your 5 friends can authorize up to 10 machines simultaneously.
