+Usage - React rehydration gate
+------------------------------
+
+**Preqrequisite: to be used with: [Usage - inside a reducer](#usage---inside-a-reducer) or similar**
+
+```tsx
+import { FC, PropsWithChildren } from 'react';
+import { useSelector } from 'react-redux';
+import ReactDOM from 'react-dom/client';
+import store, { RootState } from './store';
+
+const RehydrateGate: FC<PropsWithChildren> = ({ children }) => {
+  const isRehydrated = useSelector<RootState>((state) => state.reduxRemember.isRehyrdated);
+  return isRehydrated
+    ? children
+    : <div>Rehydrating, please wait...</div>;
+};
+
+const root = ReactDOM.createRoot(
+  document.getElementById('root')!
+);
+
+root.render(
+  <Provider store={store}>
+    <RehydrateGate>
+      <App />
+    </RehydrateGate>
