 Static prerendering is the process of generating static HTML files for your application. This can be useful for either improving the performance of your application, as it allows you to serve pre-rendered HTML files to users without having to generate them on the fly or for deploying static sites to platforms that do not support server-side rendering.

+## Automatic Static Route Discovery
 
-TanStack Start can prerender your application to static HTML files, which can then be served to users without having to generate them on the fly. To prerender your application, you can add the `prerender` option to your tanstackStart configuration in `vite.config.ts` file:
+When you don't specify a `pages` array in your prerendering configuration, TanStack Start will automatically discover and prerender all static routes in your application. This includes:
+
+- Routes with no path parameters (e.g., `/about`, `/contact`)
+- Routes with search parameters that have default values
+- Routes that don't require dynamic data fetching
+
+Routes with path parameters (e.g., `/users/$userId`) are excluded from automatic discovery since they require specific parameter values to be prerendered.
