 Run the following command within your project directory to install the Auth0 Next.js SDK:

+npm install @auth0/nextjs-auth0@beta
 ```
 
 The SDK exposes methods and variables that help you integrate Auth0 with your Next.js application using [Route Handlers](https://nextjs.org/docs/app/building-your-application/routing/route-handlers) on the backend and [React Context](https://reactjs.org/docs/context.html) with [React Hooks](https://reactjs.org/docs/hooks-overview.html) on the frontend.

 In the root directory of your project, add the file `.env.local` with the following [environment variables](https://nextjs.org/docs/basic-features/environment-variables):
 
 - `AUTH0_SECRET`: A long secret value used to encrypt the session cookie. You can generate a suitable string using `openssl rand -hex 32` on the command line.
-- `AUTH0_BASE_URL`: The base URL of your application.
-- `AUTH0_ISSUER_BASE_URL`: The URL of your Auth0 tenant domain. If you are using a [Custom Domain with Auth0](https://auth0.com/docs/custom-domains), set this to the value of your Custom Domain instead of the value reflected in the "Settings" tab.
+- `APP_BASE_URL`: The base URL of your application.
+- `AUTH0_DOMAIN`: The URL of your Auth0 tenant domain. If you are using a [Custom Domain with Auth0](https://auth0.com/docs/custom-domains), set this to the value of your Custom Domain instead of the value reflected in the "Settings" tab.
 - `AUTH0_CLIENT_ID`: Your Auth0 application's Client ID.
 - `AUTH0_CLIENT_SECRET`: Your Auth0 application's Client Secret.
 
 The SDK will read these values from the Node.js process environment and automatically configure itself.
 
-## Add the dynamic Route Handler {{{ data-action=code data-code="app/api/auth/[auth0]/route.js" }}}
+## Create the Auth0 SDK Client {{{ data-action=code data-code="src/lib/auth0.ts" }}}
+
+Create a file at `src/lib.auth0.ts`. This file provides methods for handling authentication, sessions and user data. 
+
+Then, import the `Auth0Client` class from the SDK to create an instance and export it as `auth0`. This instance is used in your app to interact with Auth0. 
+
+## Add the Authentication Middleware {{{ data-action=code data-code="src/middleware.ts" }}}
 
 ::: note
-This QuickStart targets the Next.js [App Router](https://nextjs.org/docs/app). If you're using the [Pages Router](https://nextjs.org/docs/pages), check out the example in the SDK's [README](https://github.com/auth0/nextjs-auth0#page-router).
+The Next.js Middleware allows you to run code before a request is completed. 
 :::
 
-Create a file at `app/api/auth/[auth0]/route.js`. This is your Route Handler file with a [Dynamic Route Segment](https://nextjs.org/docs/app/building-your-application/routing/route-handlers#dynamic-route-segments).
+Create a file at `src/middleware.ts`. This file is used to enforce authentication on specific routes. 
 
-Then, import the `handleAuth` method from the SDK and call it from the `GET` export. This creates the following routes:
+The `middleware` function intercepts incoming requests and applies Auth0's authentication logic. 
+The `matcher` configuration ensures that the middleware runs on all routes except for statis files and metadata. 
 
-- `/api/auth/login`: The route used to perform login with Auth0.
-- `/api/auth/logout`: The route used to log the user out.
-- `/api/auth/callback`: The route Auth0 will redirect the user to after a successful login.
-- `/api/auth/me`: The route to fetch the user profile from.
+## Add the Landing Page Content {{{ data-action=code data-code="src/app/page.tsx" }}}
 
-## Add the `UserProvider` component {{{ data-action=code data-code="app/layout.jsx" }}}
+The Landing page `src/app/page.tsx` is where users interact with your app. It displays different content based on whether the users is logged in or not. 
 
-On the frontend side, the SDK uses React Context to manage the authentication state of your users. To make that state available to all your pages, you need to override the [Root Layout component](https://nextjs.org/docs/app/building-your-application/routing/pages-and-layouts#root-layout-required) and wrap the `<body>` tag with a `UserProvider` in the file `app/layout.jsx`.
+Edit the file `src/app/page.tsx` to add the `auht0.getSession()` method to determine if the user is logged in by retrieving the user session. 
 
-The authentication state exposed by `UserProvider` can be accessed in any Client Component using the `useUser()` hook.
+If there is no user session, the method returns `null` and the app displays the **Sign up** or **Log in** buttons.
+If a user sessions exists, the app displays a welcome message with the user's name and a **Log out** button. 
 
-::::checkpoint
-:::checkpoint-default
-Now that you have added the route handler and `UserProvider`, run your application to verify that your application is not throwing any errors related to Auth0.
+::: note
+The Logout functionality is already included in the file `src/app/page.tsx`. 
+When the user selects the **Log out** button, they are redirected to the Auth0 logout endpoint, which clears their session and redirects back to your app.

-Sorry about that. Here's a couple of things to double check:
-* Are your environment variables populated correctly?
-* did you put the `app/api/auth/[auth0]/route.js` and `app/layout.jsx` files in the correct folder?
-* make sure the domain and client ID are configured correctly

-Users can now log in to your application by visiting the `/api/auth/login` route handler provided by the SDK. Add a link that points to the login route using an **anchor tag**. Clicking it redirects your users to the Auth0 Universal Login Page, where Auth0 can authenticate them. Upon successful authentication, Auth0 will redirect your users back to your application.
+```sh
+npm run dev
+``` 
 
-:::note
-Next linting rules might suggest using the `Link` component instead of an anchor tag. The `Link` component is meant to perform [client-side transitions between pages](https://nextjs.org/docs/api-reference/next/link). As the link points to an API route and not to a page, you should keep it as an anchor tag.
-:::
+Visit the url `http://localhost:3000` in your browser.

+You will see:
+- A **Sign up** and **Log in** button if the user is not authenticated.
+- A welcome message and a **Log out** button if the user is authenticated.
