Paste this into Claude Code to set it up:
Create a CLAUDE.md file at the root of your project. Include sections for: project overview (what this project does and what tech stack it uses), common commands (build, test, lint, deploy), coding conventions (style rules, import patterns, error handling), architecture notes (how the codebase is organized), and gotchas (things Claude cannot infer from reading the code). Keep it concise and actionable. Claude reads every word, so bloated instructions dilute the important ones.
