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 Tutorials get outdated in weeks.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 60+ 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

🔑 Golden Rules

1. Always review diffs before accepting changes — Claude suggests, you decide
2. Use /compact before context hits 70% — prevention beats recovery
3. Be specific in requests — Include WHAT, WHERE, HOW, VERIFY
4. Start with Plan Mode for risky/complex tasks — read-only exploration first
5. Create CLAUDE.md for every project — single source of truth

Context management is critical. See the Cheat Sheet for thresholds and actions.
