+### `useDebugValue`
+
+```js
+useDebugValue(value)
+```
+
+`useDebugValue` can be used to display a label for custom hooks in React DevTools.
+
+For example, consider the `useFriendStatus` custom hook described in ["Building Your Own Hooks"](/docs/hooks-custom.html):
+
+```js{6-8}
+function useFriendStatus(friendID) {
+  const [isOnline, setIsOnline] = useState(null);
+
+  // ...
+
+  // Show a label in DevTools next to this hook
+  // e.g. "FriendStatus: Online"
+  useDebugValue(isOnline ? 'Online' : 'Offline');
+
+  return isOnline;
+}
+```
+
+> Tip
+>
+> We don't recommend adding debug values to every custom hook. It's most valuable for custom hooks that are part of shared libraries.
