+### TanStack Router
+
+TanStack Router supports custom links through its `createLink` helper function.
+The snippet below shows the most basic implementation, wrapping a Material UI Link component.
+See [TanStack Router—Custom Link](https://tanstack.com/router/latest/docs/framework/react/guide/custom-link) for more component integration examples.
+
+```tsx
+import { createLink } from '@tanstack/react-router';
+import { Link as MUILink } from '@mui/material';
+
+const CustomLink = createLink(MUILink);
+
+function App() {
+  return (
+    <CustomLink underline="none" to="/about">
+      Link to about page
+    </CustomLink>
+  );
+}
+```
