18. Documentation Automation

AI turns dreaded documentation into a quick task. Generate README, API docs, docstrings in seconds.

(Spoiler: "I'll document it later" has been every developer's lie since 1970. AI finally makes it possible. Your PM is suspicious. 📝)

What AI Can Generate

  • README.md: Paste code → "Generate README"
  • API Documentation: From OpenAPI/Swagger or code
  • Inline Comments: Copilot suggests docstrings
  • Architecture Docs: Claude analyzes codebase → writes ADRs
  • Changelogs: From git commits

Best Practices

  • ✓ AI generates draft, you refine
  • ✓ Use for boilerplate (function descriptions), not strategic content
  • ✓ Always review for accuracy
