About This Guide

Our Pedagogical Approach

Unlike reference manuals that simply list features, this guide follows a learning journey designed to take you from beginner to power user. We focus on:

• Understanding why before diving into how
• Real-world patterns you can use immediately
• Progressive complexity — start simple, master advanced techniques at your pace
• Practical workflows over theoretical concepts

Think of this as your mentor for mastering Claude Code — not just documentation.

Origins & Philosophy

This guide is the result of several months of daily practice and research with Claude Code, Anthropic's AI coding assistant CLI. Whether you're exploring agentic development, LLM-powered coding workflows, or AI pair programming, this resource covers everything from basic setup to advanced MCP server orchestration.

I don't claim to be an "expert" — I'm simply sharing what I've learned along the way, humbly hoping to help my peers and evangelize good practices in AI-assisted development.

Key inspirations for this work:

• Claudelog.com — Excellent tips, patterns & tutorials (highly recommended)
• zebbern/claude-code-guide — Comprehensive reference & troubleshooting guide with cybersecurity focus

Important note: This guide was largely generated with the help of AI. As such, it likely contains errors, inaccuracies, or outdated information. I would be delighted to receive any feedback, corrections, or — even better — pull requests to improve it. Don't hesitate to open an issue or submit a PR!

⚠️ WINDOWS USERS - IMPORTANT DISCLAIMER

I work on macOS and have not personally tested Windows-specific commands (PowerShell, batch files, path syntax).

What this means for you:

• PowerShell scripts are AI-generated and may need adjustment
• Path separators (\ vs /) may be incorrect in some examples
• Batch file hooks may require debugging
• Git Bash commands should work as-is (they use Unix syntax)

How you can help:

1. Open an issue if you find Windows-specific problems
2. Submit a PR with corrections (Windows testers highly appreciated!)
3. Join our community discussions to share Windows-specific tips

Status: We are actively seeking Windows contributors to improve platform support.

Language: I wrote this guide in English by default to reach a wider audience, but French is my native language. I could easily translate it to French myself, or leverage AI and community contributions for other languages. Let me know if translations would be useful!

Quick Start

# Install Claude Code (all platforms)
npm install -g @anthropic-ai/claude-code

# Or on macOS/Linux only:
curl -fsSL https://claude.ai/install.sh | sh

# Start in your project
cd your-project
claude

Windows Users: Use %USERPROFILE%\.claude\ instead of ~/.claude/ for all paths in this guide.

The 7 Commands You Need

Command	Action
/help	Show all commands
/status	Check context usage
/compact	Compress context (>70%)
/clear	Fresh start
/plan	Safe read-only mode
/rewind	Undo changes
Ctrl+C	Cancel operation

Context Management (Critical!)

Context %	Action
0-50%	Work freely
50-70%	Be selective
70-90%	/compact now
90%+	/clear required

---

The Golden Rules

1. Always review diffs before accepting changes
2. Use /compact before context gets critical (>70%)
3. Be specific in requests (WHAT, WHERE, HOW, VERIFY)
4. Start with Plan Mode for complex/risky tasks
5. Create CLAUDE.md for every project
