Claude Code MasterClass For Everyone (Part 1): Installation & Build Your First App

From zero to your first working AI agent, no coding experience needed.

Everyone thinks Claude Code is only for hardcore developers.

It’s not.

You don’t need to be technical to use the most powerful AI builder tool today.

But saying and doing are different things.

That’s why I’m starting a series.

In Part 1, we’ll install Claude Code and start building.

Zero coding.

Too much promise?

Scroll down and see the app we built.

Or better, let me show you.

Fast-Forward: What We’re Building

I love Notion.

So let’s build ours.

Of course, there are a few features, but this is just Part 1 of the masterclass.

For more, you need to go deeper.

But if you do not yet know what Claude Code is, let’s start with the fundamentals.

1. What is Claude Code?

What is Claude Code?

Claude Code is a terminal-based AI agent.

It can read, edit, generate, and run code directly on your machine.

It comes in 3 forms:

• CLI tool

• Extensions

  • VS Code & Antigravity or different IDE’s.

You talk to it. It builds anything for you.

Not just apps.

Save all your articles to it.

Let it be written in your tone.

2. How to Install Claude Code?

Just paste the code into your Terminal, and let it install

Claude Code works on Windows, Mac, and inside coding tools.

Pick your method.

If you don’t like building on Terminal like me, skip to C) or D).

A) Windows

Open PowerShell and paste this:

irm https://claude.ai/install.ps1 | iex

Takes 2 minutes.

Alternative

winget install Anthropic.ClaudeCode

It wants your sign-in after pasting the code, sign-in and you are ready.

B) Mac

Open Terminal and paste this:

curl -fsSL https://claude.ai/install.sh | bash

Takes 2 minutes.

Alternative

brew install --cask claude-code

C) VS Code Extension (Preferred)

Download VS Code, head to “Extensions” and download the Claude Code

This is the easiest method. (That’s what I use daily.)

Step 1: Download VS Code: Go here.

Step 2: Open VS Code

Step 3: Find Extensions: Click the Extensions icon on the left sidebar (or press Cmd+Shift+X on Mac, Ctrl+Shift+X on Windows)

Step 4: Search Claude Code: Type “Claude Code” in the search bar

Step 5: Install: Click “Install” on the Claude Code extension by Anthropic.

Step 6: Initate: Click on the Claude Code extension, and click on the Claude symbol.

After sending the message, it will ask you to sign in through your browser.

Complete the sign-in process, authenticate your app, and you’re good to go.

D) Antigravity (Power Users)

Antigravity Console

If you already used Claude Code before, try this.

I am using it for complex tasks.

Step 1: Download Antigravity

Go to here and → Download

Step 2: Sign in with a Google Account

Open Antigravity → Sign in with Google

Sign-in, Antigravity

Step 3: Download Claude Code Extension

Extensions

Inside Antigravity: Extensions → Search “Claude Code” → Install

Claude Code Extension

Step 4: Use Claude Code + Antigravity Agents. Now you have both:

Claude Code & Antigravity Agents Side by Side

- Claude Code for building

- Antigravity Agents for advanced workflows

(We’ll cover Antigravity deep-dive in the next parts.)

3. Your First AI Agent

This will be your first win.

a. Create a Project in Your Folder

My First Agent

You can do it manually.

Go to your desktop and create a new folder.

b. Open Your Coding Tool

Let’s say you are using VS Code.

Open Vs Code.

Click on “Open”

Open the folder you just created inside VS Code

Select your folder.

Go to extensions, click Claude Code, and open it.

After selecting the folder, go to extension, click on Claude Code, and open it

Everything is ready!

Now, let’s start building.

c. Copy/Paste This Prompt

Now here’s where the magic happens.

I’m giving you a prompt from my Vault.

(800+ prompts, including 70+ Claude Code-specific ones.)

This single prompt builds your “agent.

Note: The vault is available only to the inner circle subscriptions or paid subs before Jan 20. For more, read this.

Pour yourself a coffee.

Open Netflix.

You’ll build your first app while sipping your coffee and watching your favorite TV series.
