+# React-admin With TanStack Start
+
+React-admin supports [TanStack Router](https://tanstack.com/router/latest) as an alternative to react-router. This allows you to use react-admin in a TanStack Start application.
+
+## Installation
+
+Install the TanStack Router adapter and the required router packages:
+
+```bash
+npm install react-admin ra-router-tanstack @tanstack/react-router @tanstack/history
+# or
+yarn add react-admin ra-router-tanstack @tanstack/react-router @tanstack/history
+```
+
+## Configuration
+
+Configure `Admin` to use `tanStackRouterProvider`:
+
+```tsx
+import { Admin, Resource, ListGuesser } from 'react-admin';
+import { tanStackRouterProvider } from 'ra-router-tanstack';
+import { dataProvider } from './dataProvider';
+
+const App = () => (
+    <Admin
+        dataProvider={dataProvider}
+        routerProvider={tanStackRouterProvider}
+    >
+        <Resource name="posts" list={ListGuesser} />
+        <Resource name="comments" list={ListGuesser} />
+    </Admin>
+);
+
+export default App;
+```
+
+## Next Steps
+
+For standalone vs embedded setups, see the [TanStack Router Integration](./TanStackRouter.md).
