+**Background**
+
+With this flag, Remix no longer sends the full route manifest up to the client on initial load. Instead, Remix only sends the server-rendered routes up in the manifest and then fetches the remaining routes as the user navigated around the application. Additional details are available in the [docs][lazy-route-discovery] and the [blog post][lazy-route-discovery-blog-post]
+
+👉 **Enable the Flag**
+
+```ts filename=vite.config.ts
+remix({
+  future: {
+    v3_lazyRouteDiscovery: true,
+  },
+});
+```
+
+**Update your Code**
+
+You shouldn't need to make any changes to your application code for this feature to work.
+
+You may find some usage for the new [`<Link discover>`][discover-prop] API if you wish to disable eager route discovery on certain links.

 Config-based routing is the new default in React Router v7, configured via the `routes.ts` file in the app directory. Support for `routes.ts` and its related APIs in Remix are designed as a migration path to help minimize the number of changes required when moving your Remix project over to React Router v7. While some new packages have been introduced within the `@remix-run` scope, these new packages only exist to keep the code in `routes.ts` as similar as possible to the equivalent code for React Router v7.
