Controller to PC With a Wireless Connection
You need a Bluetooth adapter or onboard Bluetooth for this, but it's also easy.

With the Pro Controller charged, press and hold the Sync button on the top of the gamepad for a few seconds until the indicator lights start flashing.

Open the system tray and right-click the Bluetooth icon.

Click "Add Bluetooth Device."

Click "Add Bluetooth or other device."

Click "Bluetooth" (because Windows needs to be reassured that you really want to use Bluetooth).

The Pro Controller should show up on the list of available devices (if it doesn't, make sure the indicator lights are still flashing back and forth). Click it, and pair the controller.

Now you can move on to Steam setup.

Steam Setup
To make sure everything works as it should between the Pro Controller and your PC game, you should use Steam's Big Picture mode, the couch-friendly lean-back menu system that works well with a gamepad.

If Steam doesn't open automatically into Big Picture when you connect the Pro Controller, open Steam and enter the Settings menu.

Click General Controller Settings, which opens a full-screen, Big Picture window.

Click "Switch Pro Configuration Support."

If the Pro Controller is connected, the mouse cursor should disappear and you should be able to navigate Big Picture with the gamepad. You can toggle "Use Nintendo Button Layout" depending on whether you prefer the A/B/X/Y buttons to be mapped as they are on the Pro Controller (clockwise X, A, B, Y from the top), or as they're mapped on an Xbox controller (clockwise Y, B, A, X from the top).
