+- Template variables: `{{VERSION}}`, `{{SWURL}}`, `{{PDFURL}}`
+
+## Publishing Workflow
+
+The legacy system implements a comprehensive publishing workflow:
+
+```mermaid
+flowchart TD
+    START[User Selects Package] --> CONFIG[Load Package Config]
+    CONFIG --> COLLECT[Collect Build Data]
+    COLLECT --> FOGBUGZ[Query FogBugz for Release Notes]
+    FOGBUGZ --> GENERATE[Generate Release Notes Document]
+    GENERATE --> PACKAGE[Package Files for Upload]
+    PACKAGE --> UPLOAD[Upload to S3]
+    UPLOAD --> ZENDESK[Update Zendesk Article]
+    ZENDESK --> UPDATE[Update Package Configuration]
+    UPDATE --> COMPLETE[Publishing Complete]
+    
+    subgraph "Document Generation"
+        GENERATE --> WORD[Use Word Template]
+        WORD --> PDF[Convert to PDF]
+    end
+    
+    subgraph "File Processing"
+        PACKAGE --> ZIP[Compress if Configured]
+        ZIP --> DELETE[Delete Old Versions]
+    end
+```
+
+### Release Notes Generation
+
+**Technology**: Microsoft Office Interop (Word automation)
+
+**Process**:
+1. Load DOCX template from configured path
+2. Replace template variables with build data
+3. Include FogBugz release notes from case events
+4. Generate final document output
+
+**Template Variables**:
+- Version information from build numbers
+- Release notes from FogBugz case events
+- Build dates and project information
+
+## Configuration Options
+
+### Software Package Configuration
+Each package supports the following options:
+
+- **Project Mapping**: Links to specific CC.NET projects
+- **Version Tracking**: Maintains published version history
+- **File Processing**: Compression and cleanup options
+- **Cloud Storage**: S3 bucket and path configuration
+- **Help Center**: Zendesk article ID and template text
+- **Release Notes**: Word template path and generation settings
+
+### System-Wide Settings
+- **Build Root**: Base directory for build artifacts
+- **Local Publish Root**: Staging directory for local processing
+- **External Service Credentials**: Stored in configuration XML
+
+## Key Implementation Patterns
+
+### Configuration Management
+- XML serialization for persistent configuration
+- Automatic deserialization on application startup
+- Support for multiple software package definitions
+
+### Error Handling
+- Global exception handling in main application thread
+- User-friendly error dialogs with stack trace details
+- Logging integration for debugging
+
+### UI Architecture
+- Windows Forms with custom controls
+- Data binding for project and build information
+- Progress tracking for long-running operations
+
+### External Service Abstraction
+- Wrapper classes for each external integration
+- Configuration-driven service connections
+- Token and credential management
+
+## Security Considerations
+
+**⚠️ Security Issues Identified**:
+
+1. **Hardcoded Credentials**: API keys and credentials are stored in plaintext in source code files:
+   - AWS credentials in `S3Client.cs:19-20`
+   - Zendesk credentials in `ZendeskClient.cs:18-19`
+   - FogBugz token in `FogbugzClient.cs:14`
+
+2. **Configuration File Exposure**: `Configuration.xml` contains sensitive information in plaintext
+
+3. **No Credential Rotation**: Static credentials without rotation mechanisms
+
+## Recommendations for Modern Implementation
+
+### Architecture Migration
+1. **Service-Oriented**: Migrate from monolithic WinForms to microservices
+2. **Web-Based UI**: Replace WinForms with modern web interface
+3. **Container-Based**: Dockerize services for deployment flexibility
+
+### Security Improvements
+1. **Secrets Management**: Implement proper secrets management (Azure Key Vault, AWS Secrets Manager)
+2. **OAuth/OIDC**: Replace API keys with modern authentication
+3. **Environment-Based Config**: Use environment variables for sensitive data
+
+### Technology Modernization
+1. **.NET Core/8**: Upgrade from .NET Framework
+2. **Entity Framework**: Replace manual XML configuration with database
+3. **Background Jobs**: Use Hangfire or similar for async processing
+4. **SignalR**: Add real-time updates for build status
+
+## Data Migration Strategy
+
+### Configuration Data
+- **Source**: `Configuration.xml` with hardcoded package definitions
+- **Target**: PostgreSQL database with `Packages`, `StorageProviders`, `HelpCenterProviders` tables
+- **Migration**: Parse XML and insert into normalized database schema
+
+### Historical Data
+- **Build History**: Maintain existing CC.NET integration patterns
+- **FogBugz Data**: Preserve case linking and release note associations
+- **Publishing History**: Create audit trail for package publications
+
+## Questions for Implementation Phase
+
+1. **CC.NET Version**: What version of CruiseControl.NET is currently deployed?
+2. **FogBugz API**: Are there any API rate limits or authentication changes needed?
+3. **Document Templates**: Should Word template processing be migrated to a different solution?
+4. **Legacy Data**: How much historical build and publication data should be migrated?
+5. **Deployment Environment**: Will the new system run on the same infrastructure or be cloud-native?
