It looks technical. It’s not.

I set it up in under an hour with zero coding background. No developer friends on speed dial, no YouTube rabbit holes about programming. Just a laptop, a few free downloads, and a willingness to follow instructions.

If you can install an app on your computer and type a sentence, you can do this.

I’m Kate, and I run a marketing studio called The Igniting Studio. I use Claude Code every single day to write posts, build proposals, create content calendars, and manage client work. It is the backbone of everything I do now. And the setup? Genuinely easier than configuring a WordPress plugin.

This guide walks you through every step. By the end, you will have Claude Code running on your machine, loaded with your business context, and ready to write your first piece of marketing content.

What You’ll Need Before Starting

Before we get into the steps, make sure you have three things ready:

  1. A computer (Mac or Windows, either works)
  2. An Anthropic account with API access. Go to console.anthropic.com and sign up. You will need to add a payment method since Claude Code uses API credits, but it is surprisingly affordable for what you get.
  3. About 45 minutes of uninterrupted time

That is it. No special hardware, no paid software, no technical background required.

Step 1: Install VS Code

VS Code is a free text editor made by Microsoft. Think of it as a smarter version of Notepad. It is where you will interact with Claude Code.

Download it from code.visualstudio.com and install it like any other app. Just click through the defaults.

Once it is installed, open it. You will see a welcome screen. You can close that. The important thing is the terminal at the bottom of the screen. If you do not see it, click Terminal in the top menu and then New Terminal. This little text box at the bottom is where the magic happens.

Step 2: Install Node.js

Node.js is a tool that lets your computer run certain programs, including Claude Code. You do not need to understand how it works. You just need it installed.

Download it from nodejs.org. Choose the version labeled LTS (Long Term Support). Install it with the default settings. That is it.

To confirm it worked, open the terminal in VS Code and type:

node --version

If you see a version number (something like v20.11.0), you are good to go. If you see an error, restart VS Code and try again.

Step 3: Install Claude Code

Now for the actual installation. In your VS Code terminal, type this command:

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

Press Enter and wait. It will take a minute or two. You will see a bunch of text scrolling by. That is normal. When it finishes and you see your cursor blinking again, Claude Code is installed.

That single command is the entire installation. No configuration screens, no setup wizards. Done.

Step 4: Create Your Project Folder

Claude Code works inside a project folder. This is just a regular folder on your computer where you keep everything related to your business or marketing work.

Open your file explorer and create a folder. Call it something simple like my-marketing or your business name. Inside it, create a few subfolders:

my-marketing/
  clients/
  content/
  skills/

Now in VS Code, click File > Open Folder and select your new project folder. You should see your subfolders in the sidebar on the left.

Step 5: Write Your CLAUDE.md File (This Is the Important Part)

This is where most people skip ahead and miss the most valuable step.

The CLAUDE.md file is a plain text file that lives in the root of your project folder. It tells Claude Code who you are, what your business does, how you write, and what rules to follow. Every time you start a session, Claude Code reads this file and uses it as context for everything it does.

Think of it as onboarding a new team member. The better your CLAUDE.md, the better the output.

In VS Code, right-click in the sidebar and choose New File. Name it exactly CLAUDE.md. Then paste in something like this template and customize it for your business:

# My Marketing Project

## About My Business
- Business name: [Your business name]
- What I do: [One sentence about what you offer]
- Target audience: [Who you serve]
- Website: [Your URL]

## Brand Voice
- Tone: [e.g., warm and professional, casual and fun, direct and no-nonsense]
- Words I use often: [list a few]
- Words I never use: [list a few]
- Example sentence in my voice: [write one]

## Current Clients
- [Client 1]: [what you do for them]
- [Client 2]: [what you do for them]

## Content Rules
- Always write in first person
- Keep paragraphs short (2-3 sentences max)
- No jargon unless the audience expects it
- [Add your own rules here]

## Platforms I Post On
- [e.g., LinkedIn, Instagram, newsletter]
- [Include any platform-specific rules]

Save the file. This is the foundation of your entire setup. You can keep adding to it over time. The more specific you are, the more Claude Code sounds like you instead of a generic AI.

Here is the key insight: the CLAUDE.md file is what makes Claude Code different from just pasting a prompt into ChatGPT. Your rules, your voice, your client details are loaded automatically every single time. You never have to repeat yourself.

Step 6: Run Your First Task

You are ready. In the VS Code terminal, type:

claude

Press Enter. Claude Code will start up and read your CLAUDE.md file. You will see a text prompt waiting for your input.

Now type something like:

Write me a LinkedIn post about why small businesses should stop overthinking their content and just start posting.

Press Enter and watch it work. Within seconds, you will get a LinkedIn post written in your brand voice, following your rules, tailored to your audience. No copying and pasting your brand guidelines. No “act as a marketing expert” prompts. It just knows.

Try a few more:

Write an Instagram caption for a behind-the-scenes photo of me working on a client project.
Draft a short email to a potential client introducing my services.
Give me 5 blog post ideas for my target audience.

Each response will follow the rules you set in your CLAUDE.md file. That is the power of the setup.

What to Do in Your First Week

Once you have Claude Code running, here are some tasks to try during your first week:

The first week is about training the system. Every edit to your CLAUDE.md makes the next output better.

Common Mistakes to Avoid

Skipping the CLAUDE.md file. Without it, Claude Code is just a generic AI. The CLAUDE.md is what makes it yours. Do not skip this step.

Making the CLAUDE.md too vague. “Write in a professional tone” is not enough. What does professional mean for your brand? Give examples. Be specific about words you like and words you avoid.

Trying to do everything on day one. Start with simple tasks. A single social post. A short email. Build confidence before asking it to write a full website.

Not updating the CLAUDE.md over time. Your business evolves. Your voice sharpens. New clients come in. Keep your CLAUDE.md current. I update mine almost weekly.

Expecting perfection without editing. Claude Code is fast and good, but it is still a tool. Read the output. Edit it. Make it yours. Over time, the edits get smaller and smaller as the CLAUDE.md gets better.

Frequently Asked Questions

Do I need to know how to code to use Claude Code?

No. You need to type commands into a terminal, but that is just typing words and pressing Enter. If you followed this guide, you already did the hardest part. The day-to-day use is just writing in plain English.

How much does Claude Code cost to run?

Claude Code uses Anthropic API credits. For a typical marketing workload (writing posts, emails, content planning), expect to spend between $10 and $50 per month. It depends on how much you use it. You can monitor your usage in the Anthropic console.

What is the difference between Claude Code and just using ChatGPT?

ChatGPT is a chat window. You paste in context every time, re-explain your brand voice, and hope it remembers. Claude Code runs locally on your machine, reads your project files automatically, and follows your rules every session without being told. It also reads and writes files directly, so it can update your content calendar, save posts to folders, and manage your project structure.

Can I use Claude Code for client work?

Absolutely. Create a separate folder for each client inside your clients/ directory. Add client-specific notes, brand guidelines, and past content. Claude Code will use all of it as context when generating work for that client.

What if I get stuck during setup?

The most common issues are: Node.js not being installed properly (restart VS Code and try node --version again), or the npm install command failing due to permissions. On Mac, try adding sudo before the npm command. On Windows, try running VS Code as administrator. If you are still stuck, the Claude Code documentation at docs.anthropic.com has troubleshooting guides.

Start Building Your Marketing System Today

The setup is the easy part. The real value comes from what you build on top of it. Your CLAUDE.md will grow. Your folder structure will fill with content. Your workflow will get faster every week.

I went from spending hours writing individual posts to generating an entire content calendar in minutes. Not because the AI is magic, but because I took the time to set it up properly with my voice, my rules, and my business context built in.
