The most complete guide to Claude Code on GitHub — and it just gained 4,232 stars in a single day to hit 9,800+ total, making it the #2 trending repo right now. claude-howto is a structured, visual, example-driven learning path that takes you from zero to advanced Claude Code usage. It covers 10 tutorial modules with Mermaid diagrams explaining internal mechanics, copy-paste configuration templates, and real-world workflow examples. The guide is split into three tracks. The beginner track (~2.5 hours) covers slash commands, memory, and basic skills. The intermediate track (~3.5 hours) covers subagents, MCP protocol, and hooks. The advanced track (~5 hours) covers checkpoints, planning mode, extended thinking, background tasks, headless mode, session management, agent teams, scheduled tasks, Chrome integration, channels, and voice dictation. Version 2.2.0 (March 2026) is compatible with Claude Code 2.1+ and works with Sonnet 4.6, Opus 4.6, and Haiku 4.5. The repo includes a self-assessment quiz to identify your knowledge gaps, interactive lesson quizzes, and even offline EPUB generation if you want to read on an e-reader. What makes this different from Anthropic's official docs: it's built for practitioners. Every concept comes with a working template you can copy-paste into your own setup. The Mermaid diagrams make complex workflows (like hook event chains and agent orchestration) visually parseable in seconds. And the progressive structure means you're not drowning in advanced features before you've mastered the basics. If you use Claude Code daily and haven't gone through this guide, you're almost certainly missing features that would save you hours. The 25+ hook event types alone are worth the read — most people only use 3-4 of them.
