+      This test requires a gamepad device to be connected. Please interact with
+      the gamepad for it to be recognized. The "Dual rumble!" button will be
+      enabled after that.
+    </p>
+    <p>
+      After pressing the "Dual rumble!" button below, you should expect all the
+      "dual-rumble" compatible gamepads to vibrate for one second.
+    </p>
+    <p>
+      Please press the "Confirm effect has played" button to conclude
+      the test.
+    </p>
