Core Documentation Principles
1. API Documentation
- Document ALL endpoints with clear descriptions
- Include complete request/response examples
- Show error responses for each endpoint
- Document authentication requirements
- Use OpenAPI/Swagger specifications
- Include code samples in multiple languages
- Document rate limits and throttling
2. Code Documentation
- Document all public APIs and interfaces
- Explain complex logic and algorithms
- Use meaningful comments that add value
- Keep documentation in sync with code
- Document configuration options
- Include usage examples
- Write JSDoc/docstrings for functions
3. README Files
A good README includes:
- Project overview (what and why)
- Quick start / installation steps
- Basic usage examples
- Configuration options
- Contributing guidelines
- License information
- Badges (build status, version, coverage)
- Links to full documentation
4. Architecture Documentation
- System overview and high-level design
- Component diagrams (use ASCII/Mermaid)
- Data flow diagrams
- Decision rationale (use ADRs)
- Security architecture
- Infrastructure diagrams
- Integration points
5. User Guides
- Step-by-step instructions
- Progressive complexity (beginner → advanced)
- Screenshots for UI documentation
- Troubleshooting section with common issues
- FAQ section
- Best practices
- Tips and tricks
6. Writing Style
- Use clear, simple language
- Write in active voice
- Be consistent (terms, formatting, tone)
- Use numbered lists for steps
- Use bullet points for options
- Include code blocks with syntax highlighting
- Keep paragraphs short
7. Documentation Tools & Formats
- Markdown for most documentation
- OpenAPI/Swagger for APIs
- Mermaid/PlantUML for diagrams
- JSDoc for code
- Docusaurus/VitePress for static sites
- GitBook for team documentation
8. Documentation Maintenance
- Review docs regularly for accuracy
- Update with every code change
- Remove outdated content promptly
- Track documentation coverage
- Set up documentation CI/CD
- Use linters for consistency
- Implement documentation reviews
9. Interactive Documentation
- API playgrounds with live requests
- Try-it features for endpoints
- Embedded code editors
- Interactive tutorials
- Sandbox environments
- Code samples that run
10. Developer Experience
- Create self-service documentation
- Design onboarding guides
- Build developer portals
- Implement search functionality
- Add quick navigation
- Include feedback mechanisms

Architecture Decision Records (ADR)
# ADR-001: Use PostgreSQL for user data
## Status: Accepted
## Context
We need to store user data persistently.
## Decision
We will use PostgreSQL database.
## Consequences
- Requires database migration
- Need to handle connection pooling
