Why This Guide?
The problem: Awesome-lists give links, not learning paths. Official docs are dense. Tutorials get outdated in weeks.
This guide: Structured learning path with 69 copy-paste templates, from first install to advanced workflows.
Reading time: Quick Start ~15 min. Full guide ~3 hours (most read by section).
By Florian BRUNIAUX | Founding Engineer @Méthode Aristote
👥 Not a Developer?
Claude Cowork is the companion guide for non-technical users (knowledge workers, assistants, managers).
Same agentic capabilities as Claude Code, but through a visual interface with no coding required.

🔑 Golden Rules
- Always review diffs before accepting changes — Claude suggests, you decide
- Use
/compactbefore context hits 70% — prevention beats recovery - Be specific in requests — Include WHAT, WHERE, HOW, VERIFY
- Start with Plan Mode for risky/complex tasks — read-only exploration first
- Create CLAUDE.md for every project — single source of truth
Context management is critical. See the Cheat Sheet for thresholds and actions.
