- Contributing guide

### API Documentation
- Endpoint reference with request/response examples
- Authentication and error codes
- Rate limits and pagination
- SDK examples

### Runbook
- When to use this runbook
- Prerequisites and access needed
- Step-by-step procedure
- Rollback steps
- Escalation path

### Architecture Doc
- Context and goals
- High-level design with diagrams
- Key decisions and trade-offs
- Data flow and integration points

### Onboarding Guide
- Environment setup
- Key systems and how they connect
- Common tasks with walkthroughs
- Who to ask for what

## 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 **Keep it current** — Outdated docs are worse than no docs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
