 ## Gamepad Input
 
+Checking if a gamepad is connected is easy! Gamepads can be connected to slots 0-3.
+
+```cs
+if (Inputs.GamepadExists(0))
+{
+    var gamepad = Inputs.GetGamepad(0);
+}
+```
+
+`GetGamepad` will throw if a gamepad is not connected so you should make sure to check `GamepadExists` before using it.
+
 MoonWorks assumes your gamepad has a left stick, a right stick, and two triggers. The stick axes are represented in the range [-1f, 1f] and the trigger axes in the range [0f, 1f];
 
 ```cs
-var leftStickHorizontal= Inputs.GetGamepad(0).LeftX;
-var rightStickVertical = Inputs.GetGamepad(0).RightY;
-var leftTrigger = Inputs.GetGamepad(0).LeftTrigger;
+var leftStickHorizontal = gamepad.LeftX;
+var rightStickVertical = gamepad.RightY;
+var leftTrigger = gamepad.LeftTrigger;
+```
+
+You can also set controller vibration by providing left and right motor amounts and a duration in milliseconds.
+
+```cs
+var leftMotorAmount = 0.2;
+var rightMotorAmount = 0.5;
+var durationInMilliseconds = 10;
+gamepad.SetVibration(leftMotorAmount, rightMotorAmount, durationInMilliseconds)
 ```
