What is Claude Code?
If you have used ChatGPT or the standard Claude.ai interface, you are used to a chatbot. You ask a question, it gives you text.
Claude Code is different. It is an *agent*. It does not just give you text; it actively reads the files on your computer, writes new code, creates folders, and runs terminal commands. It is the difference between asking an architect for a blueprint (Claude.ai) and hiring a general contractor to build the house (Claude Code).
Why It Intimidates Beginners
Claude Code runs in the command line (the terminal). For non-technical users, seeing a black screen with text is terrifying. It feels like you are hacking the mainframe.
You aren't. The terminal is just a text-based way to talk to your computer, and Claude Code makes it incredibly simple.
How to Start (Step-by-Step)
Step 1: Install Node.js
Claude Code requires Node.js to run. Go to nodejs.org, download the installer, and click "Next" until it finishes.
Step 2: Open Your Terminal
On a Mac, open the app called "Terminal". On Windows, open "Command Prompt".
Step 3: Install Claude Code
Type this exact command and press Enter:
`npm install -g @anthropic-ai/claude-code`
Step 4: Authenticate
Type `claude` and press Enter. It will open a browser window asking you to log in to your Anthropic account.
Step 5: Start Building
Create an empty folder on your desktop. Drag that folder onto your terminal window (this tells the terminal to look at that folder). Type `claude` again.
Now, just type what you want: *"Create a new HTML file with a beautiful, dark-mode landing page for my wellness coaching business."*
Claude Code will read the folder, create the file, write the HTML and CSS, and tell you when it is done.
The One Rule You Must Follow
Always create a `CLAUDE.md` file in your folder before you start. Write your instructions, colors, and rules in that file. Claude Code automatically reads it every time it starts, ensuring it never forgets your brand guidelines or compliance rules.
