# Create Architecture Documentation

Generate comprehensive architecture documentation

## Instructions

1. **Architecture Analysis and Discovery**
   - Analyze current system architecture and component relationships
   - Identify key architectural patterns and design decisions
   - Document system boundaries, interfaces, and dependencies
   - Assess data flow and communication patterns
   - Identify architectural debt and improvement opportunities

2. **Architecture Documentation Framework**
   - Choose appropriate documentation framework and tools:
     - **C4 Model**: Context, Containers, Components, Code diagrams
     - **Arc42**: Comprehensive architecture documentation template
     - **Architecture Decision Records (ADRs)**: Decision documentation
     - **PlantUML/Mermaid**: Diagram-as-code documentation
     - **Structurizr**: C4 model tooling and visualization
     - **Draw.io/Lucidchart**: Visual diagramming tools

3. **System Context Documentation**
   - Create high-level system context diagrams
   - Document external systems and integrations
   - Define system boundaries and responsibilities
   - Document user personas and stakeholders
   - Create system landscape and ecosystem overview

4. **Container and Service Architecture**
   - Document container/service architecture and deployment view
   - Create service dependency maps and communication patterns
   - Document deployment architecture and infrastructure
   - Define service boundaries and API contracts
   - Document data persistence and storage architecture

5. **Component and Module Documentation**
   - Create detailed component architecture diagrams
   - Document internal module structure and relationships
   - Define component responsibilities and interfaces
   - Document design patterns and architectural styles
   - Create code organization and package structure documentation

6. **Data Architecture Documentation**
   - Document data models and database schemas
   - Create data flow diagrams and processing pipelines
   - Document data storage strategies and technologies
   - Define data governance and lifecycle management
   - Create data integration and synchronization documentation

7. **Security and Compliance Architecture**
   - Document security architecture and threat model
   - Create authentication and authorization flow diagrams
   - Document compliance requirements and controls
   - Define security boundaries and trust zones
   - Create incident response and security monitoring documentation

8. **Quality Attributes and Cross-Cutting Concerns**
   - Document performance characteristics and scalability patterns
   - Create reliability and availability architecture documentation
   - Document monitoring and observability architecture
   - Define maintainability and evolution strategies
   - Create disaster recovery and business continuity documentation

9. **Architecture Decision Records (ADRs)**
   - Create comprehensive ADR template and process
   - Document historical architectural decisions and rationale
   - Create decision tracking and review process
   - Document trade-offs and alternatives considered
   - Set up ADR maintenance and evolution procedures

10. **Documentation Automation and Maintenance**
    - Set up automated diagram generation from code annotations
    - Configure documentation pipeline and publishing automation
    - Set up documentation validation and consistency checking
    - Create documentation review and approval process
    - Train team on architecture documentation practices and tools
    - Set up documentation versioning and change management
