Getting Started with Claude Code

You've probably heard of AI tools like ChatGPT and Claude. But did you know there's a tool that lets you go from idea to finished app, tested and deployed, without knowing how to code?

It's called Claude Code, and it changes the game for what's possible.

What is Claude Code?

Claude Code is a command-line tool (CLI) from Anthropic that lets you talk to the AI model Claude directly in your terminal. But it's so much more than a chatbot. Think of having an experienced developer at your side who can:

• Build entire applications from your description
• Test the code and fix bugs automatically
• Deploy your app so others can use it
• Explain every step in a way you understand

Why is this interesting for you?

If you have an idea for an app, a tool, or an automation, you've previously faced a choice: learn to code (months/years) or hire a developer (expensive). Claude Code changes that equation.

Some examples of what you can build:

• Your first web app: Describe what you want, and Claude builds it for you
• Automations: Create tools that save you hours every week

There are more use cases like organizing files and analyzing documents. I'll cover these in an upcoming post about Claude Cowork, a newer application from Anthropic. But in this guide, we focus on the most powerful aspect: going from idea to working product.

Getting Started

Step 1: Install Node.js

Claude Code needs something called Node.js to work. Don't worry, it's easier than it sounds.

1. Go to nodejs.org
2. Download the LTS version (recommended)
3. Run the installer

Step 2: Install Claude Code

Open your terminal (on Mac it's called "Terminal", on Windows "Command Prompt" or "PowerShell") and type:

npm install -g @anthropic-ai/claude-code

Press Enter and wait for the installation to complete.

Step 3: Log in with your Anthropic account

The easiest way to use Claude Code is to log in with your Anthropic account. In your terminal, type:

claude

The first time you run the command, you'll be asked to choose a login method. Choose to log in with your Anthropic account (via the browser).

Step 4: Start your first project

Now you're ready! Create a new folder for your project and navigate to it:

mkdir my-project
cd my-project
claude

You can now start describing what you want to build.

Your First Experiment: Build a Simple App

Try writing something like:

I want to build a simple web app where users can type in text
and get it translated to pirate speak. Explain every step you take.

Claude will:

1. Create the project structure
2. Write the code
3. Explain what each part does
4. Help you test that everything works

Tips for Beginners

1. Start simple: Build something small first before tackling your dream project
2. Be specific: The clearer you describe what you want, the better the result
3. Read the explanations: Claude often explains what it's doing. Take time to understand, that's how you learn
4. Iterate: It's rarely perfect the first time. Ask Claude to adjust and improve

What Can You Build?

With Claude Code and some patience, you can build almost anything:

• Web apps and tools
• Automations that save you time
• Prototypes for business ideas
• Internal tools for your company

The most important thing is that you dare to try. You will make mistakes, things will break, and that's perfectly okay. That's how you learn.

Next Steps

Once you're comfortable with the basics, you can explore:

• Deploy your app so others can use it (Vercel, Netlify)
• Connect databases to save information
• Integrate with other services and APIs

Claude Code is a gateway to a world where your ideas are no longer limited by technical knowledge. It's not about becoming a programmer. It's about bringing to life what's in your head.
