-Next, inside the same folder let's create `alokai-context.tsx` file, where we will create Alokai context that will be shared across the application:

-import { User, Cart } from "@vsf-enterprise/sapcc-types";

-This will return an `AlokaiProvider` provider and `useSdk` hook, that will allow us to use the same SDK instance across client side application.
-It also will return a set of hooks that will allow us to access the state of the application.
-In order to use our shared SDK and state instances, we need to wrap our Next.js application in the `AlokaiProvider` provider component. Along with initializing the `AlokaiProvider` you can pass initial data related to currencies and locales. Create a new file inside the same directory named `provider.tsx` and add the following code inside:
-
-```typescript
-"use client";
-
-import { ReactNode } from "react";
-import { AlokaiProvider } from "./sdk";
-import { getSdk } from "./sdk.config";
-
-export function Providers({ children }: { children: ReactNode }) {
-  return (
-    <AlokaiProvider
-      initialData={{
-        currencies: ['USD', 'EUR'],
-        currency: ['USD'],
-        locale: 'en',
-        locales: ['en', 'de'],
-      }}
-      sdk={getSdk()}
-    >
-      {children}
-    </AlokaiProvider>
-  );
-}
-```
-Now, wrap your application with `<Providers>` in `apps/storefront/app/layout.tsx`:
-
-```typescript
-import { Providers } from "../sdk/provider";
-// imports and metadata object stays the same
-
-export default function RootLayout({
-  children,
-}: {
-  children: React.ReactNode;
-}): JSX.Element {
