-The library implements the main functionality in the core module. Update this section with:
-
-1. **Key Classes**: Describe main classes and their responsibilities
-2. **Core Functions**: Document important functions and their purpose
-3. **Data Flow**: Explain how data flows through the system
-4. **Dependencies**: List and explain key dependencies

 ## Development Notes
 
-- Uses Python {{ cookiecutter.python_version }}+ with modern type hints (PEP 604)
+- Uses Python {{ cookiecutter.python_version }}+ with modern type hints
 - Configured with ruff for linting/formatting and mypy for type checking
 - Built with uv for dependency management
 - Includes invoke tasks for common operations
-- Version {{ cookiecutter.version }} ({{ cookiecutter.year }})
-
-## Implementation Guidelines
-
-- Follow test-driven development practices
-- Use descriptive function names and one-liner docstrings for non-trivial functions
-- Keep files between 300–500 lines where possible
-- Don't duplicate code; build upon existing implementations
-- Always use type hints as supported by Python {{ cookiecutter.python_version }}+
