+### With tooltip
+
+You can wrap the toggle button with a tooltip to provide additional information.
+
+```tsx live
+import { useState } from "react";
+
+export default function Demo() {
+  const [selected, setSelected] = useState(false);
+
+  return (
+    <HvTooltip title={selected ? "Turn off" : "Turn on"}>
+      <HvToggleButton onClick={() => setSelected(!selected)}>
+        {selected ? <LightOn /> : <LightOff />}
+      </HvToggleButton>
+    </HvTooltip>
+  );
+}
+```
