+## UI5 Web Components React - Next.js Pages Router Example
+
+This example shows how to use the [Next.js](https://nextjs.org/) Pages Router with UI5 Web Components for React.
+It includes the required adjustments in `src/pages/_app.tsx` and `src/pages/_document.tsx` as well as a very simple Todo
+App.
+
+## How to use this template
+
+```bash
+npx degit SAP/ui5-webcomponents-react/examples/nextjs-pages#main my-project
+cd my-project
+```
+
+## Getting Started
+
+First, install the node_modules:
+
+```bash
+npm install
+# or
+yarn install
+# or
+pnpm install
+```
+
+Then, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `src/pages/index.tsx`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed
+on [http://localhost:3000/api/todods](http://localhost:3000/api/todos). This endpoint can be edited
+in `src/pages/api/todos.ts`.
+
+The `src/pages/api` directory is mapped to `/api/*`. Files in this directory are treated
+as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions
+are welcome!
