What is CLAUDE.md?

CLAUDE.md is a configuration file placed in a project's root directory that provides the AI assistant with specific rules, project context, and custom instructions for that particular codebase. It acts as a set of persistent guidelines that the AI reads at the start of every session to ensure its code suggestions align with your project's coding standards, tech stack, and architectural patterns.
