Setting up a PS4 controller is a simple process that only takes a few minutes. First, make sure that the PS4 console is turned off. Then, connect the controller to the PS4 using a USB cable. Once the controller is connected, press the PlayStation button in the center of the controller to turn it on. The controller will now be paired with the PS4 and can be used wirelessly. To disconnect the controller, simply press and hold the PlayStation button for 3 seconds. The controller will then turn off and can be removed from the console.
