Claude HowTo: Visual Guide to Claude Code

Key Takeaways#

• Claude HowTo is a 10-lesson visual guide that takes you from Claude Code basics to advanced agent architectures
• Every lesson includes copy-paste templates you can drop into your project for immediate value
• The guide is synced with every Claude Code release (currently v2.1.119, April 2026)
• Includes interactive quizzes at the end of each lesson to test your understanding

What Is Claude HowTo?#

Claude HowTo is a comprehensive visual guide to Claude Code by luongnv89. With 30,100+ GitHub stars, it's one of the most popular community resources for learning Claude Code. The guide uses diagrams, annotated screenshots, and worked examples to explain concepts that are hard to grasp from documentation alone.

The project is continuously updated to match the latest Claude Code release. When Anthropic ships new features, the guide updates within days with new lessons and revised templates.

Lesson Structure#

The 10 lessons follow a progressive difficulty curve:

Beginner (Lessons 1-3)#

1. Getting Started — Installation, first session, basic commands
2. Understanding CLAUDE.md — How Claude Code reads project context and how to write effective instructions
3. Basic Workflows — Code generation, file editing, and running commands

Intermediate (Lessons 4-6)#

1. Configuration Hierarchy — How CLI, project, and user-level settings interact and override each other
2. Custom Commands — Building slash commands that automate repetitive workflows
3. MCP Integration — Connecting external tools, databases, and APIs to Claude Code

Advanced (Lessons 7-10)#

1. Hooks and Lifecycle Events — Automating actions before and after Claude Code operations
2. Subagents — Spawning parallel AI assistants for complex multi-step tasks
3. Agent Skills — Building reusable, composable skill packages
4. CLI Mastery — Advanced command-line usage, scripting, and CI/CD integration

Copy-Paste Templates#

Every lesson includes ready-to-use templates:

• CLAUDE.md templates for different project types (web app, API, library)
• Custom command definitions for common workflows
• MCP configuration snippets for popular services (GitHub, Slack, databases)
• Hook scripts for pre-commit validation and post-edit formatting
• Subagent prompts for code review, testing, and documentation generation

Interactive Quizzes#

Each lesson ends with a quiz that tests your understanding of the concepts covered. Questions range from multiple-choice to scenario-based problems where you identify the correct configuration or command.

Format Options#

The guide is available in multiple formats:

• GitHub README — Browse lessons directly on GitHub
• EPUB — Download for offline reading on e-readers and tablets
• PDF — Print-friendly version with all diagrams and examples

Who Should Use This#

• Developers new to Claude Code who want a structured learning path instead of piecing together docs
• Experienced users looking to master advanced features like subagents and hooks
• Teams onboarding new members to Claude Code with a consistent curriculum
• Trainers and educators who need teaching materials with built-in assessments

Why It Stands Out#

Most Claude Code resources are either official docs (comprehensive but dry) or blog posts (engaging but shallow). Claude HowTo occupies the sweet spot: visually rich, progressively structured, and continuously updated. The copy-paste templates give you instant value, while the quizzes ensure you actually understand what you're copying. The multi-format releases (EPUB, PDF) make it accessible beyond the browser.
