How to connect DualShock 4 controller to a PC

"I had a pleasure to hold a lot of controllers, but DualShock 4 is without a doubt my favorite. Not only because of the shape and the arrangement of buttons, but also because of pure practicality. Firstly – it’s compatible with PlayStation 3, so when I want to play a game on the older generation, I don’t have to get used to a different controller. Secondly – it does an excellent job as a PC controller, and the touchpad is a salvation in games that don’t have native support for controllers and require frequent clicking on some icons or windows."
