# Claude Code Crash Course 🚀  [](https://twitter.com/EdenMarco177) [](LICENSE) [](https://www.udemy.com/course/claudecode/?referralCode=JAN-2026) Welcome to the Claude Code Crash Course! This repository is designed to teach you the fundamentals and advanced concepts of Claude Code, Anthropic's official CLI for AI-powered software development, in a hands-on way. ## What is Claude Code? 💡 Claude Code is an interactive command-line interface that brings Claude's AI capabilities directly to your development workflow. It helps with code analysis, bug fixing, feature development, refactoring, and workflow automation - all from your terminal. ## How it Works 🤔 This repository uses a unique branch-based structure for learning: 1. **Each `project/*` branch covers a specific Claude Code feature or concept.** 2. **Within each branch, commits are ordered chronologically.** Follow the commits one by one to learn the topic step-by-step. Simply check out the branch for the topic you want to learn and walk through the commits! ## Available Topics (Branches) 📚 Here are the topics currently available: | Branch | Topic | Description | |--------|-------|-------------| | `project/custom-commands` | 🔧 Custom Commands | Learn to extend Claude Code with custom functionality like dad joke generators and automated commits | | `project/mcp` | 🔗 MCP Integration | Master Model Context Protocol integration with Context7 MCP server | | `project/context-engineering-mcp` | ⚡ Fine-Grained MCP Configuration | Optimize context tokens with task-specific MCP configurations using `--mcp-config` flag | | `project/subagents` | 🤖 Subagents | Build specialized AI agents within Claude Code like Code Comedy Carl | | `project/hooks-notifications` | 🎣 Hooks & Notifications | Automate your workflow with sound notifications and event triggers | | `project/hookhub` | 🏢 Hook Hub | Advanced hook management and organization systems | *More topics might be added, so keep an eye out!* ## Prerequisites 🛠️ Before you start, make sure you have the following installed: * 🤖 Claude Code CLI * 📦 Git * 🐍 Python (version 3.8 or higher) * 📝 Your favorite text editor/IDE ## Getting Started ▶️ 1. **Clone the repository:** ```bash git clone https://github.com/emarco177/claude-code-crash-course.git cd claude-code-crash-course ``` 2. **Choose a topic and check out the branch:** ```bash # Example for the custom commands topic git checkout project/custom-commands ``` 3. **Follow the commits:** Use `git log --oneline --reverse` to see the chronological list of commits for the branch. Then, use `git checkout <commit_hash>` or your Git client to step through the history and learn. ## Contributing 🤝 Contributions are welcome!
