Practice real workflows - experience Claude Code in action

🚀 Getting Started (Your First Steps with GitHub)

If you're new to GitHub and want to learn by working with this project, follow these beginner-friendly steps:

Step 1: Understanding GitHub

Repository (repo): A project folder stored on GitHub containing all the code and files
Clone: Download a copy of the repository to your computer
Commit: Save your changes with a description of what you did
Push: Upload your changes back to GitHub

Step 2: Clone This Repository

# First, install Git on your computer if you haven't already
# Then open your terminal/command prompt and run:

git clone https://github.com/firstprinciplescg/Claude-Code-Guide-for-Beginners.git
cd Claude-Code-Guide-for-Beginners

What this does: Downloads all the project files to your computer so you can work with them.

Step 3: Set Up the Development Environment

# Install Node.js dependencies (the tools this project needs)
npm install

# Start the development server (launches the website locally)
npm run dev

What this does:

npm install downloads all the tools and libraries this project uses
npm run dev starts a local web server so you can see the website at http://localhost:5173

Step 4: Make Your First Changes

Open the project in your favorite text editor (VS Code recommended)
Try changing some text in src/sections/Introduction.jsx
Save the file and watch your browser automatically update!

Step 5: Your First Commit (Saving Your Work)

# Check what files you've changed
git status

# Add your changes to be committed
git add .

# Create a commit with a descriptive message
git commit -m "Update introduction text to personalize the guide

- Changed welcome message to include my name
- Updated example to reflect my learning goals
- This commit shows I successfully set up the development environment"

# Upload your changes to GitHub (if you have push access)
git push origin main

Understanding Commit Messages:

First line: Short summary (50 characters or less)
Blank line: Separates summary from detailed explanation
Body: Explain what you changed and why (optional but helpful)
Good practice: Use present tense ("Add feature" not "Added feature")
