Pages Router: Set up a new Next.js app | Next.js
First, letâ€™s make sure that your development environment is ready. If you donâ€™t have Node.js installed, install it from here. Youâ€™ll need Node.js version 18 or higher. Youâ€™ll be using your own text editor and terminal app for this tutorial. If you are on Windows, we recommend downloading Git for Windows and use Git Bash that comes with it, which supports the UNIX-specific commands in this tutorial
