You Can Build Web Apps. Yes, You.#

Maybe you're a designer who wants to bring your ideas to life. Maybe you're in marketing and tired of waiting for developers. Or maybe you're just curious about how apps are made.

Good news: you don't need a computer science degree. You don't need to understand everything before you start. You just need to follow along.

What We'll Do

Download an app called Cursor
Use Cursor's AI assistant to set up everything else
Run your first code

That's it. The AI will guide you through any technical stuff.

First, Let's Understand What We're Installing#

Before we start downloading things, here's a quick overview of what each tool does. Don't worry about memorizing this—you can always come back to reference it.

The Tools We'll Use

Tool	What It Is	Simple Analogy
Cursor	A smart text editor for writing code	Like Microsoft Word, but for code, with an AI assistant built in
Node.js	A program that runs JavaScript code	Like a translator that turns your code into actions
NVM	Node Version Manager - installs and manages Node.js	Like an app store specifically for Node.js versions
npm	Node Package Manager - comes with Node.js	Like a library where you can borrow pre-built code
Git	Tracks changes to your code	Like "Track Changes" in Word, but more powerful

Why These Specific Tools?

These are the standard tools used by millions of web developers. Once you learn them, you can work on almost any web project and understand tutorials across the internet.

Step 1: Download and Install Cursor#

Let's start with the easiest part—downloading Cursor. It's just like installing any other app on your computer.

What is Cursor?#

Cursor is a code editor with an AI assistant built right in. Think of it as a smart notepad where you write code, and you have an AI friend sitting next to you who can:

Write code for you based on what you describe
Explain any code you don't understand
Run commands on your computer
Fix errors and debug problems
Answer any questions you have

Download Cursor

Go to cursor.com
Click the download button for your operating system (Mac, Windows, or Linux)
On Mac: Open the downloaded file and drag Cursor to your Applications folder
On Windows: Run the installer and follow the prompts (click "Next" a few times)
Open Cursor

When you first open Cursor, it will ask you to sign in or create an account. This only takes a minute—you can use your Google or GitHub account, or create a new one with your email.

Step 2: Getting to Know Cursor's Interface#

Before we start installing other tools, let's take a quick tour of Cursor so you know where things are.

Don't Worry About Memorizing

You don't need to remember all of this right now. Just get a general sense of the layout. You'll become familiar with it naturally as you use it.

The Main Areas#

When you open Cursor, you'll see something like this:

Left Side: File Explorer

Shows all the files and folders in your project
Like the folder view in Finder (Mac) or File Explorer (Windows)

Center: Editor

Where you write and edit code
Can have multiple files open in tabs, like a web browser

Bottom: Terminal

A text-based way to interact with your computer
This is where commands run (don't worry, the AI will help you with this)
If you don't see it, press Ctrl + ` (the backtick key, usually above Tab)

Right Side: AI Chat (when open)

Your AI assistant lives here
Open it with Cmd + I (Mac) or Ctrl + I (Windows)

The Most Important Shortcut#

The only shortcut you really need to remember right now:

Cmd + I (Mac) or Ctrl + I (Windows) — Opens the AI chat

This is your lifeline. Whenever you're stuck or don't know what to do, open the AI chat and ask.

Step 3: Let the AI Check Your Computer#

Now let's use Cursor's AI to see what's already installed on your computer. This is where the magic happens—instead of typing mysterious commands yourself, you'll just ask the AI to do it.

Open the AI chat by pressing Cmd + I (Mac) or Ctrl + I (Windows).

Then click the button below to open this prompt directly in Cursor, or copy and paste it into the chat:

What's Happening?

When you send this prompt, the AI will run some commands in the terminal (the text area at the bottom of Cursor). It's looking at your system to see what's already there. Read what it tells you—it will explain what it found and what to do next.

Step 4: Install NVM#

NVM (Node Version Manager) is a tool that makes it easy to install Node.js. Why use NVM instead of installing Node.js directly? Because:

It's easier to update Node.js later
You can switch between different versions if needed
It avoids permission problems that can happen with direct installation

This Might Take a Few Minutes

Depending on your operating system, the AI might need to install some prerequisites first (like Homebrew on Mac). This is normal—just follow along with what it tells you. If it asks you to close and reopen Cursor (or the terminal), do that and then continue.

Step 5: Install Node.js#

Now that NVM is installed, we can use it to install Node.js. Node.js is what actually runs your web applications—it's the engine that makes everything work.

What is LTS?

LTS stands for "Long Term Support." It's the most stable, reliable version of Node.js—the one recommended for most people. New features come out in other versions first, but LTS is tested and trusted.

Step 6: Create Your First Project#

You now have everything you need installed! Let's create a simple project to make sure it all works—and to give you the satisfaction of running your first code.

You Did It!

If you see "Hello World!" in your terminal, congratulations! You just ran your first code. Everything from here is just building on what you've already done.

What Did We Just Install?#

Let's recap what's now on your computer and why each piece matters:

Your New Toolkit

Cursor — Your home base. This is where you'll write code, ask the AI for help, and run commands. You'll spend most of your time here.

NVM — The installer for Node.js. You probably won't interact with it much after today, but it's there when you need to update Node.js or switch versions.

Node.js — The engine that runs JavaScript code. When you build web apps, Node.js is what makes them work. It's running behind the scenes.

npm — Came bundled with Node.js. This lets you download and use code that other people have written—like building blocks you can snap together.

Where to Go From Here#

Your computer is now set up for web development. Here are some project starters to build real apps—just like tools like Lovable or v0, but right here in Cursor:

Troubleshooting#

Things don't always go perfectly—that's normal in programming. If you hit a problem, describe it to the AI:

Errors Are Normal

Every developer—even experts with decades of experience—sees errors constantly. Errors aren't a sign that you did something wrong; they're just how computers communicate problems. The AI can help you understand and fix almost any error you encounter.

You're Ready#

That's it. You have:

Cursor — A powerful code editor with AI assistance
Node.js — Everything you need to run web applications
Prompts — Ready-to-use starting points for any question

The most important thing to remember: you don't need to understand everything to get started. Understanding comes from doing. Keep building small things, keep asking questions, and keep going.

Every expert was once a beginner who just didn't give up.

Welcome to web development. You've got this.
