Getting Started with Mastering Claude

Welcome! This guide will help you navigate the learning path based on your experience level and goals.

Choose Your Starting Point

🚀 Complete Beginner (Never used Claude Code)

Start here: Lesson 00: Quick Start (5 minutes)

This gets you a quick win and introduces the core concept.

Then follow the full path:

• Lesson 04: CLAUDE.md basics
• Lesson 05: Effective prompting
• Lesson 06: Plan mode
• Lesson 07: Memory system

Time investment: ~2 hours for lessons 00-07, then practice on real projects.

💼 Experienced Developer (Used Claude Code a few times)

You probably know: Basic prompting, file editing, running commands

You should learn:

1. Lesson 04: CLAUDE.md - Most high-leverage habit
2. Lesson 06: Plan Mode - Prevent wasted work
3. Lesson 11: Large Codebases - Navigate efficiently
4. Lesson 15: Parallelization - Work faster

Skip: Lesson 00 (too basic for you)

Time investment: ~1.5 hours, immediate productivity gains.

🔥 Power User (Using Claude Code daily)

You already know: CLAUDE.md, prompting, plan mode

You should explore:

1. Lesson 08: Hooks - Automate your workflow
2. Lesson 09: MCP Servers - Extend capabilities
3. Lesson 10: Custom Skills - Build reusable commands
4. Lesson 16: Advanced Patterns - Expert techniques

Also grab: CHEAT-SHEET.md for quick reference

Time investment: 2-3 hours spread over a week. Implement as you learn.

Learning Paths by Goal

Reference this when something goes wrong.

The Core Principle

Every lesson teaches variations of one core idea:

Invest upfront in context (CLAUDE.md, memory, skills) → Claude performs better → Never repeat yourself → Productivity compounds over time

The best Claude Code users spend time setting up their environment once, then benefit from it in every session forever.

Time Expectations

Minimum viable mastery: 1-2 hours

• Lessons 00, 04, 06
• Read the cheat sheet
• Practice on one real project

Comfortable proficiency: 3-4 hours

• Lessons 00-07, 11, 15
• Review examples
• Set up CLAUDE.md for your main project

Expert level: 15-20 hours

• All 30 lessons (00-29) plus exercises
• Implement hooks and skills
• Set up MCP servers
• Practice advanced patterns, model routing, and prompt caching

Ongoing: 5-10 minutes per week refining CLAUDE.md based on what you learn

Study Tips

Do the exercises. Reading without practicing won't make you proficient.

Apply immediately. After each lesson, use it on real work. Theory → Practice → Mastery.

Iterate on CLAUDE.md. Your first CLAUDE.md will be basic. That's fine. Improve it every week.

Ask Claude for help. "Explain how plan mode works" or "Help me write a better CLAUDE.md for this project"

Don't rush. Better to master the first few lessons than to skim all 30.

What Success Looks Like

After completing this curriculum, you should:

✅ Have a comprehensive CLAUDE.md for your main project ✅ Use plan mode automatically for non-trivial tasks ✅ Batch requests for efficiency ✅ Maintain useful project memory ✅ Have at least 2-3 custom skills ✅ Understand when to use MCP servers ✅ Know how to recover when Claude makes mistakes ✅ Be 3-5x more productive than when you started
