+
+The `ShopifyProvider` component wraps your entire app and provides support for hooks.
+You should place it in your app's entry point component. For example, `&lt;App&gt;`.
+
+## Example code
+
+```tsx
+import {ShopifyProvider} from '@shopify/hydrogen';
+import shopifyConfig from '../shopify.config';
+
+export default function App() {
+  return (
+    <ShopifyProvider shopifyConfig={shopifyConfig}>
+      {/* Routes, Pages, etc */}
+    </ShopifyProvider>
+  );
+}
+```
+
+## Component type
+
+The `ShopifyProvider` component is a shared component, which means that it renders on both the server and the client. For more information about component types, refer to [React Server Components](/custom-storefronts/hydrogen/framework/react-server-components).
