Summary

Create comprehensive documentation including Architecture Decision Records (ADRs), OpenAPI/Swagger specs for all endpoints, operational runbooks, troubleshooting guides, and developer onboarding materials to ensure knowledge sharing and operational excellence.

Background

Current documentation gaps:

• No Architecture Decision Records (ADRs) documenting key decisions
• API endpoints documented in code but no OpenAPI specs
• No operational runbooks for incident response, rollback, recovery
• Limited troubleshooting guides
• Basic developer onboarding materials

Acceptance Criteria

Architecture Decision Records:

• ADR documenting microservices vs monolith decision
• ADR for Node.js/TypeScript selection for healthcare
• ADR for PostgreSQL database choice
• ADR for Turborepo monorepo approach
• ADR for Docker/Kubernetes deployment strategy
• ADR template for future decisions

API Documentation:

• OpenAPI 3.0 specs for all service endpoints
• Interactive API documentation (Swagger UI)
• Request/response examples for all endpoints
• Error code reference documentation
• Authentication flow diagrams

Operational Runbooks:

• Incident response procedures
• Deployment rollback steps
• Database recovery procedures
• Service failover procedures
• Security incident response
• HIPAA breach notification process

Troubleshooting Guides:

• Common error scenarios and solutions
• Performance troubleshooting guide
• Database connection issues
• Authentication problems
• Service communication failures

Developer Onboarding:

• Development environment setup guide
• Code contribution guidelines
• Testing requirements and patterns
• Code review checklist
• Release process documentation

Implementation Steps

1. Phase 1: ADRs (Week 1)

   • Create ADR template
   • Document key architectural decisions

2. Phase 2: API Documentation (Week 2)

   • Create OpenAPI specs for all services
   • Set up Swagger UI hosting

3. Phase 3: Runbooks (Week 2-3)

   • Document operational procedures
   • Create troubleshooting guides

4. Phase 4: Developer Docs (Week 3)

   • Update onboarding materials
   • Document development workflows

5. Phase 5: Review & Maintenance (Week 4)

   • Review all documentation
   • Establish documentation update process

Documentation Principles

1. Keep docs close to code - Store in /docs in repository
2. Version control - All docs in Git
3. Living documents - Update as code changes
4. Examples over text - Show, don't just tell
5. Accessibility - Clear language, diagrams, search
