+On Next.js App Router, put the provider in a client component and render it once in your layout:
+
 ```tsx
-// app/layout.tsx (or your root layout)
+// app/providers.tsx (a client component)
+'use client';
 import { AffitorProvider } from '@affitor/sdk/react';
 
-export default function RootLayout({ children }) {

+// app/layout.tsx (Next.js App Router): render it once around your app
+import { Providers } from './providers';
+
+export default function RootLayout({ children }: { children: React.ReactNode }) {
   return (
-    <html>

-        </AffitorProvider>
+        <Providers>{children}</Providers>
       </body>
     </html>
   );
 }
 ```
 
+The provider runs in the browser, so it lives in a client component: in the App Router, `layout.tsx` is a Server Component. With the Pages Router, wrap your app in `AffitorProvider` in `pages/_app.tsx`.

 Below the snippets, **Tracker on** your site shows **Waiting for the first visit**, **Tracker not found on your site yet**, or **First click** and how long ago it arrived. **Check now** asks Affitor to look for the tracker on your website again. Nothing is saved on this step: **Continue** turns on after the first click, and **Skip for now** moves on to Payments.
 
 The step is done once Affitor finds the tracker on your website or receives real tracking events. Signup tracking is a separate install: see [signup tracking](/docs/brand/tracking/lead-tracking-signup), and [click tracking](/docs/brand/tracking/click-tracking) for the full click guide.
