Lesson 1.1 — Course Introduction

Why This Lesson Exists

Before you install anything on your computer, you need to understand what you're actually going to do and why it works. This lesson takes 10 minutes and will save you a lot of confusion later.

The Main Idea

Not long ago, building a website meant years of learning to code.

Now there are AI agents that write code on their own. Your job is to explain clearly what needs to be done.

This is called AI coding: you provide the intent, the agent turns it into code.

What Is Claude Code

Claude Code is an AI agent that lives inside your code editor.

You write a task in plain text — it:

Creates files and folders
Writes code
Runs commands in the terminal
Fixes errors
Explains what it's doing and why

Think of yourself as the project manager and the agent as the developer on your team — except this developer never sleeps, never takes time off, and responds instantly.

What It Looks Like in Practice

Here's a real example conversation:

You: Create a page with a lead capture form. Fields: name, phone number, description of the issue. After submission, show the message "Thanks, we'll be in touch."

Claude Code: Creating the form... Let me check the project structure first. Can I run a command? [Allow]

You: Yes

Claude Code: Created src/components/ContactForm.tsx. Added field validation. Connected it to the main page. Check it at localhost:3000/contact.

You didn't write a single line of code — you just described the task.

Why This Works for Beginners

Three reasons:

1. The agent explains every action Before running anything, it tells you what it's about to do. You approve or decline.

2. Errors aren't a big deal If something breaks, just copy the error message and send it to the agent. It resolves things on its own 80% of the time.

3. You learn as you go Over time, you start understanding what the agent is doing — not because you studied, but because you watched it work.

How AI Coding Differs from ChatGPT

	ChatGPT	Claude Code
What it does	Generates text/code	Executes tasks inside your project
Files	Writes to chat, you copy manually	Creates files directly
Terminal	No	Runs commands
Remembers project	No	Reads your files and understands context
Output	Text	Working code

What's Coming Next

In the next lesson, you'll install everything you need:

VS Code — the code editor (your workspace)
Node.js — the runtime for running code
Claude Code — the AI agent

This takes 30–60 minutes and only requires following instructions — the agent will help you through any technical details.

Summary

AI coding = directing an AI agent instead of writing code yourself
Claude Code is an agent inside your editor that executes tasks in your project
Your skill is formulating tasks clearly
Errors are normal — the agent fixes them
