1. Create a new Next.js app: bash npx create-next-app my-nextjs-app

2. Navigate to the project directory: bash cd my-nextjs-app

3. Create a new layout component, for example, components/Layout.js: ```jsx // components/Layout.js import React from 'react';

const Layout = ({ children }) => { return (

); };

export default Layout; ```

1. Use the layout component in your pages. For example, in pages/index.js: ```jsx // pages/index.js import React from 'react'; import Layout from '../components/Layout';

const HomePage = () => { return (

Home Page

Welcome to my Next.js app with layout!

); };

export default HomePage; ```

1. Update other pages accordingly by importing and using the Layout component.

2. Customize the Layout component as needed for your application structure.

3. Run the Next.js app: bash npm run dev

4. Open your browser and visit http://localhost:3000 to see the app with the layout in action.

That's it! You have successfully implemented a basic layout in a Next.js app.
