#readme

Create a professional README.md for an open-source project. Essential sections: 1. Project title with logo and badges (build status, version, license). 2. One-line description and key features. 3. Installation instructions with code blocks. 4. Quick start guide with minimal example. 5. API reference or usage documentation. 6. Contributing guidelines and code of conduct link. 7. License and acknowledgments. Use clear formatting, screenshots, and GIFs for visual appeal.

Write effective code documentation. Levels: 1. Code comments (explain why, not what - complex logic only). 2. Function/method docs (parameters, return values, exceptions - JSDoc, docstrings). 3. README (setup, usage, examples). 4. API documentation (OpenAPI/Swagger for REST). 5. Architecture docs (system design, diagrams). 6. Changelog (version history). Best practices: Keep docs close to code. Update with code changes. Use examples. Avoid obvious comments. Document assumptions and edge cases. Use diagrams (C4 model, UML). Tools: Sphinx, Doxygen, MkDocs. Good code is self-documenting, but docs add context.
