To get started with Next.js, you'll need Node.js installed on your machine. You can create a new Next.js project using the following command: ```bash npx create-next-app my-next-app ``` This will set up a new Next.js project with all the necessary dependencies. You can then navigate to the project directory and start the development server with `npm run dev`.
