+# yaml2rst
+
+A Python tool for converting YAML files into reStructuredText (RST) files for the freee a11y-guidelines project.
+
+## Overview
+
+yaml2rst is a specialized content generation tool that processes YAML data files and converts them into properly formatted RST files for inclusion in the a11y-guidelines documentation. It supports multiple content types including guidelines, FAQs, checks, and reference materials, with full internationalization support.
+
+### Key Features
+
+- **Multi-language support**: Generate content for Japanese and English
+- **Template-based generation**: Flexible Jinja2 template system
+- **Modular architecture**: Clean mixin-based design for extensibility
+- **Comprehensive testing**: 99.56% test coverage with 404+ tests
+- **Performance optimized**: Efficient processing of large datasets
+- **Type safety**: Full type hints and validation
+
+## Installation
+
+### Prerequisites
+
+- Python 3.8 or higher
+- pip package manager
+
+### Dependencies
+
+The tool requires the following Python packages:
+
+```bash
+pip install jinja2 freee_a11y_gl>=0.1.0
+```
+
+### Development Dependencies
+
+For development and testing:
+
+```bash
+pip install pytest pytest-cov pytest-mock psutil flake8
+```
+
+### Installation from Source
+
+1. Clone the repository:
+```bash
+git clone <repository-url>
+cd a11y-guidelines/tools/scripts/yaml2rst
+```
+
+2. Install in development mode:
+```bash
+pip install -e .
+```
+
+## Basic Usage
+
+### Command Line Interface
+
+The primary way to use yaml2rst is through the command line:
+
+```bash
+# Generate all content for Japanese
+yaml2rst --lang ja --basedir /path/to/a11y-guidelines
+
+# Generate all content for English
+yaml2rst --lang en --basedir /path/to/a11y-guidelines
+
+# Generate specific files only
+yaml2rst --lang ja --basedir /path/to/a11y-guidelines category.rst faq_index.rst
+
+# Use custom template directory
+yaml2rst --lang ja --basedir /path/to/a11y-guidelines --template-dir /custom/templates
+
+# Export default templates for customization
+yaml2rst --export-templates
+
+# Export templates to custom directory
+yaml2rst --export-templates --template-dir /custom/templates
+```
+
+### Available Options
+
+- `--lang, -l`: Target language (ja/en)
+- `--basedir, -b`: Base directory of the a11y-guidelines project
+- `--template-dir, -t`: Custom template directory path
+- `--export-templates`: Export built-in templates and exit
+- `files`: Optional list of specific files to generate (positional arguments)
+- `--help`: Show detailed help information
+
+### Template Customization
+
+yaml2rst supports template customization through a priority-based system:
+
+```bash
+# Export default templates for customization
+yaml2rst --export-templates
+
+# Export to custom directory
+yaml2rst --export-templates --template-dir /path/to/custom/templates
+
+# Use custom templates during generation
+yaml2rst --lang ja --template-dir /path/to/custom/templates
+```
+
+**Template Resolution Priority:**
+1. Custom templates (specified via `--template-dir`)
+2. User templates (`~/.config/freee_a11y_gl/templates/`)
+3. Built-in templates (default)
+
+For detailed template customization guide, see [TEMPLATE_CUSTOMIZATION.md](docs/TEMPLATE_CUSTOMIZATION.md).
+
+### Supported Content Types
+
+yaml2rst can generate the following types of content:
+
+- **Guidelines**: Category pages with accessibility guidelines
+- **Checks**: Checklist items and examples
+- **FAQ**: Frequently asked questions and tag pages
+- **References**: WCAG mappings, priority information, and tool references
+- **Build files**: Makefiles for documentation building
+
+## Architecture Overview
+
+yaml2rst follows a modular, mixin-based architecture designed for maintainability and extensibility.
+
+### Core Components
+
+- **ContentGeneratorBase**: Foundation class combining all mixins
+- **Mixins**: Reusable functionality (RelationshipMixin, ValidationMixin, UtilityMixin)
+- **Content Generators**: Specialized classes for different content types
+- **FileGenerator**: Orchestrates the generation process
+- **TemplateManager**: Handles Jinja2 template loading and rendering
+
+### Design Patterns
+
+- **Mixin Pattern**: Shared functionality across generators
+- **Template Method**: Consistent generation workflow
+- **Singleton**: Shared resource management
+- **Factory**: Dynamic generator instantiation
+
+For detailed architectural information, see [ARCHITECTURE.md](docs/ARCHITECTURE.md).
+
+## Development
+
+### Running Tests
+
+Use the provided test runner for comprehensive testing:
+
+```bash
+# Run all tests
+python run_tests.py
+
+# Run with coverage reporting
+python run_tests.py --coverage
+
+# Run specific test categories
+python run_tests.py --type unit
+python run_tests.py --type integration
+python run_tests.py --type functional
+python run_tests.py --type performance
+
+# Run in fast mode (skip slow tests)
+python run_tests.py --fast
+
+# Run with verbose output
+python run_tests.py --verbose
+```
+
+### Test Structure
+
+The test suite is organized into three main categories:
+
+- **Unit tests** (`tests/unit/`): Individual component testing
+- **Integration tests** (`tests/integration/`): Component interaction testing
+- **Functional tests** (`tests/functional/`): End-to-end workflow testing
+
+Performance tests are integrated within these categories using pytest markers.
+
+### Code Quality
+
+The project maintains high code quality standards:
+
+- **Test Coverage**: 99.56% (target: >90%)
+- **Type Safety**: Full type hints throughout codebase
+- **Documentation**: Comprehensive docstrings and comments
+- **Code Style**: PEP 8 compliant with automated checking
+
+### Contributing
+
+1. **Fork the repository** and create a feature branch
+2. **Write tests** for new functionality (TDD approach recommended)
+3. **Ensure all tests pass** with `python run_tests.py`
+4. **Maintain or improve** test coverage percentage
+5. **Follow coding standards** and add appropriate documentation
+6. **Submit a pull request** with clear description of changes
+
+### Development Workflow
+
+1. **Set up development environment**:
+```bash
+pip install -e .
+pip install pytest pytest-cov pytest-mock psutil flake8
+```
+
+2. **Run tests during development**:
+```bash
+python run_tests.py --fast --verbose
+```
+
+3. **Check coverage before committing**:
+```bash
+python run_tests.py --coverage
+```
+
+4. **Validate code style**:
+```bash
+flake8 src/ tests/
+```

+
+## Troubleshooting
+
+### Common Issues
+
+**Import Errors**:
+- Ensure all dependencies are installed: `pip install -e .`
+- Verify Python path includes the src directory
+
+**Template Not Found**:
+- Check that template files exist in the expected location
+- Verify basedir parameter points to correct a11y-guidelines directory
+
+**Permission Errors**:
+- Ensure write permissions for output directories
+- Check file system permissions for template and data directories
+
+**Memory Issues**:
+- For large datasets, consider processing in smaller batches
+- Monitor memory usage with performance tests
+
+### Debug Mode
+
+For detailed troubleshooting information:
+
+```bash
+# Run with maximum verbosity
+python run_tests.py --verbose
+
+# Check specific test failures
+pytest tests/unit/test_specific_component.py -v
+
+# Profile performance issues
+python run_tests.py --type performance --verbose
+```
+
+### Getting Help
+
+1. **Check the documentation**: Review [ARCHITECTURE.md](docs/ARCHITECTURE.md) and [API_REFERENCE.md](docs/API_REFERENCE.md)
+2. **Run the test suite**: Often reveals configuration or environment issues
+3. **Check logs**: Enable verbose logging for detailed execution information
+4. **Review examples**: Look at existing generators for implementation patterns
+
+## Performance
+
+yaml2rst is optimized for processing large datasets efficiently:
+
+- **Benchmarks**: <0.1s per item for typical content generation
+- **Memory usage**: <100MB increase for 1000 items processing
+- **Scalability**: Linear scaling with dataset size
+- **Concurrency**: Thread-safe design for parallel processing
