Claude Code Complete Beginner Course: Set Up, Build & Deploy

Getting Started with Claude Code

What You'll Need

  • A Claude Pro subscription (minimum $17/month) to access Claude Code
  • Basic computer literacy (no coding experience required)
  • A terminal (Mac/Linux) or Command Prompt (Windows)

How to Install Claude Code

  1. Open your terminal.
  2. Run the curl command from the Claude Code docs.
  3. Authenticate with your Claude account by typing /login or following the on-screen prompts.
  4. Type claude in the terminal to start a session.

Note: Claude Code runs locally on your machine, so it can directly edit files, run scripts, and manage your computer.

The Claude Code Terminal Interface

The terminal view shows:

  • Model (e.g., Opus 4.6) and plan (e.g., Claude Max)
  • Current working directory (e.g., /users/yourname)
  • Context bar (0-100%), shows how much conversation history is left
  • Token counter, tracks usage (~20,000 tokens = 10% of full context)
  • Modes, switch between "ask before edits," "edit automatically," or "bypass permissions" using Shift+Tab
  • Fun status messages (e.g., "finagling"), customizable

Tip: Claude Code automatically compresses your conversation history to maximize context efficiency. For a deeper dive, check out the Claude Full Masterclass 2025: The Complete Guide in Tamil.

Using an IDE: VS Code & Anti-Gravity

An IDE (Integrated Development Environment) combines a folder organizer, text editor, and AI chat. The two most popular options are Visual Studio Code (Microsoft) and anti-gravity (Google).

VS Code Setup

  1. Download VS Code for your OS.
  2. Open a folder to see your files in the left panel.
  3. Click the Extensions icon (blocks), search for "Claude Code", and install the official Anthropic extension.
  4. Use the right-hand agent panel to chat with Claude Code, no terminal needed.

Anti-Gravity Setup

  1. Download anti-gravity from anti-gravity.google.
  2. Open a folder and click the Claude icon (or replace the default Gemini agent).
  3. The layout is nearly identical to VS Code, but anti-gravity has a cleaner, more modern UI with stronger AI focus.

Recommendation: Start with the GUI for simplicity, but graduate to the terminal for full power (multiple sessions, faster refresh).

Building Your First Web App

Step 1: Create a CLAUDE.md File

This file acts as your project brain, it's injected at the very top of every conversation, steering the AI's output from the start. Think of it like setting a ship's initial course: a small change here has a huge impact over long conversations.

What to include in CLAUDE.md:

  • The project's purpose and goals
  • Design preferences (colors, fonts, layout style)
  • Coding conventions (frameworks, file structure)
  • Your workflow preferences (e.g., "Always build iteratively, comparing against a reference image")

Step 2: Three Ways to Design with Claude Code

Method 1: Screenshot Loop (Recommended)

  1. Find inspiration from sites like godly.website.
  2. Take a full-page screenshot:
    • Open DevTools (Command+Shift+I or right-click > Inspect)
    • Set viewport to 1920x1080
    • Press Command+Shift+P and type "Capture full size screenshot"
  3. Compress the image to <4 MB using a tool like resizePNG
  4. Attach the image and any CSS styles to Claude Code by dragging or pasting
  5. Claude will generate the site, take screenshots of its output, compare them to the reference, and iterate until it's 95-99% accurate.

Method 2: Voice Transcript Dump

Use a voice-to-text tool (e.g., hold Fn on Mac) to dictate all your requirements. Most people speak ~200 words/minute vs. typing ~60, so this is 3x faster. Claude extracts meaning from the raw transcript to build a close approximation.

Method 3: Component Libraries

Use services like 21st.dev where designers publish reusable components. Click "copy prompt" for a component (e.g., a hero section with animated backgrounds) and paste it into Claude Code with instructions like "Install this at the top of my site."

Step 3: Deploy Your Build

Build locally first, then deploy to the internet so others can access it. Popular deployment tools:

  • Netlify, for static sites
  • Vercel, for modern frameworks (Next.js, etc.)
  • Modal, for AI/automation backends

Advanced Features

Claude Code Modes

  • Plan Mode, Claude presents a detailed plan before making changes (safe for complex builds)
  • Ask Before Edits, confirms each file modification (best for beginners)
  • Edit Automatically, applies changes immediately (balanced productivity)
  • Bypass Permissions, fastest mode, but use cautiously (best for trusted, repetitive tasks)

Context Management

  • Context is the biggest bottleneck in AI productivity
  • Keep prompts concise and high-ROI
  • Use CLAUDE.md to front-load critical instructions
  • Let Claude auto-compress history to stay within limits

Slash Commands & Hooks

  • Slash commands, shortcuts for common actions (e.g., /clear, /login, /help)
  • Hooks, custom scripts that run before/after every tool call (e.g., auto-lint your code, log actions)

Model Context Protocol (MCP)

Set up automated systems quickly:

  • Email managers
  • Bookkeepers
  • Data collection agents (via Chrome DevTools integration)

Sub-Agents & Agent Teams

  • Create specialized agent files ("skill files") that turn Claude into different experts
  • Use scoped tool access to limit what each sub-agent can do
  • Leverage the new agent team feature for parallel task execution

Session Mobility & Git Worktrees

Spin up parallel Claude sessions without conflicts using:

  • Git worktrees (isolated branches)
  • Session mobility (move sessions between machines)

Scaling & Deployment in Production

Run your automations 24/7 using:

  • Modal, serverless AI infrastructure
  • GitHub Actions, CI/CD pipelines
  • Claude Code on the web, cloud-hosted agents
