-### Apply Tracing to SSR
+#### Moving the Sentry server config file for production usage
 
-Wrap `createRootRoute` with `wrapCreateRootRouteWithSentry` in `src/routes/__root.tsx` to apply tracing to Server-Side Rendering (SSR):
+For production monitoring, you need to move the Sentry server config file to your build output. Since [TanStack Start is designed to work with any hosting provider](https://tanstack.com/start/latest/docs/framework/react/guide/hosting), the exact location will depend on where your build artifacts are deployed (for example, `"/dist"`, `".output/server"` or a platform-specific directory).

-import type { ReactNode } from "react";
-import { createRootRoute } from "@tanstack/react-router";
-import { wrapCreateRootRouteWithSentry } from "@sentry/tanstackstart-react";
+For example, when using [Nitro](https://nitro.build/), copy the instrumentation file to `".output/server"`:
 
-// (Wrap `createRootRoute`, not its return value!)
-export const Route = wrapCreateRootRouteWithSentry(createRootRoute)({
