2. Make sure you have Node.js and Yarn installed on your machine.
3. Install dependencies by running yarn install in the project directory.
4. Run the development server by running yarn dev in the project directory.
5. Open http://localhost:5000 in your browser to see the sample page with a “Hello, world!” message and a counter.
