## Principles
1. **Write for the reader** — Who is reading this and what do they need?
2. **Start with the most useful information** — Don't bury the lede
3. **Show, don't tell** — Code examples, commands, screenshots
4. **Keep it current** — Outdated docs are worse than no docs
5. **Link, don't duplicate** — Reference other docs instead of copying
