What is CLAUDE.md?

CLAUDE.md is a configuration file that lives in your project root. When Claude Code starts a session, it reads this file to understand your coding preferences, project conventions, and custom instructions.

Think of it as a "system prompt" for your codebase. Rules here teach Claude about your tech stack, coding style, and project-specific patterns.
