How do I install a ps3 controller on my PC?

Does anyone play MW3 in their PC/Laptop using their PS3 controller with motionjoy?

• If someone plays modern warfare 3 on their pc/laptop with their ps3 controller, and if you used the motionjoy program to use your controller to play this cool game, does anyone have the game controls, it seems like i cant move/ adjust every single button on my controller to move or to aim down the sights, i have gotten my controller to work with my pc and the mw3 game, but i have difficulty using the game controls because i dont know how to program the z and x axis joysticks so that i can run and move...can someone help or send me their game controll set up for the ps3 controller?
