+  <summary>How do I fetch data in Next.js?</summary>
+  Next.js provides a variety of methods depending on your use case. You can use:
+  <ul>
+    <li> Client-side rendering: Fetch data with <a href="/docs/basic-features/data-fetching/client-side.md#client-side-data-fetching-with-useeffect">useEffect</a> or <a href="/docs/basic-features/data-fetching/client-side.md#client-side-data-fetching-with-swr">SWR</a> inside your React components</li>

-  <summary>Why a new Router?</summary>
+  <summary>Why does Next.js have its own Router?</summary>
   Next.js is special in that:
   <ul>
-    <li>Routes don’t need to be known ahead of time, We don't ship a route manifest</li>
+    <li>It uses a file-system based router which simplifies the app structure</li>
+    <li>It supports shallow routing which allows you to change the URL without running data fetching methods</li>
+    <li>Routes don’t need to be known ahead of time so we don't ship a route manifest</li>
     <li>Routes are always lazy-loadable</li>
   </ul>
+    If you're migrating from React Router, see the <a href="/docs/migrating/from-react-router.md">migration documentation</a>.
