Documentation
Domain: Software Engineering
🎯 Motivation
Written guides for code: README, API docs, inline comments, tutorials. Essential for maintainability.
📋 Concrete Example
Documentation: README.md (project overview, setup, usage), API.md (endpoints, parameters, examples), docstrings (each function explained), CONTRIBUTING.md (how to contribute). Without docs, code is incomprehensible.
🔗 Analogy
Documentation is like a manual for a board game - without it, no one knows how to play. With it, anyone can learn. Code documentation is the manual for developers using or maintaining the code.
