+# Architecture
+
+## Overview
+
+This repository follows a modular, maintainable architecture designed for clarity, scalability, and long-term sustainability.
+
+## Directory Structure
+
+```
+.
+├── src/           # Source code
+├── tests/        # Test suites
+├── docs/         # Documentation
+├── scripts/      # Utility scripts
+├── config/       # Configuration files
+├── LICENSE       # License file
+├── LICENSES/     # Full license texts
+└── README.adoc   # Project documentation
+```
+
+## Design Principles
+
+- **Separation of Concerns**: Each module has a single responsibility
+- **Testability**: Code is written to be easily testable
+- **Documentation**: All public APIs are documented
+- **Configuration**: Environment-specific settings are externalized
+
+## Dependencies
+
+- External dependencies are minimized and clearly declared
+- Version pinning is used for reproducibility
+
+## Security Considerations
+
+- Sensitive data is never committed to the repository
+- Secrets are managed through environment variables or secure vaults
+- Regular dependency audits are performed
+
+## Maintainability
+
+- Code follows consistent style guidelines
+- Pull requests require review and CI checks
+- Issues and discussions are tracked transparently
