- Create a new directory for your project.
- Open a terminal and navigate to the directory you just created.
- Run the command "npm init" to create a new package.json file for your project.
- Install Express.js by running the command "npm install express".
- Create a new file, for example "app.js", and require Express at the top of the file using the following code: "const express = require('express')".
