### Doc mapping (one-to-one with official documentation)

**Guide (指南)**:
- See guide files in `examples/guide/` or `examples/getting-started/` → https://element-plus.org/en-US/guide/design

**Components (组件)**:
- See component files in `examples/components/` → https://element-plus.org/en-US/component/overview

## Examples and Templates

This skill includes detailed examples organized to match the official documentation structure. All examples are in the `examples/` directory (see mapping above).

**To use examples:**
- Identify the topic from the user's request
- Load the appropriate example file from the mapping above
- Follow the instructions, syntax, and best practices in that file
- Adapt the code examples to your specific use case

**To use templates:**
- Reference templates in `templates/` directory for common scaffolding
- Adapt templates to your specific needs and coding style

## API Reference

Detailed API documentation is available in the `api/` directory, organized to match the official Element Plus API documentation structure:

### Component API (`api/component-api.md`)

**To use API reference:**
1. Identify the API you need help with
2. Load the corresponding API file from the `api/` directory
3. Find the API signature, parameters, return type, and examples
4. Reference the linked example files for detailed usage patterns
5. All API files include links to relevant example files in the `examples/` directory

## Best Practices

1. **Use on-demand import**: Import only the components you need to reduce bundle size
2. **Use Composition API**: Prefer Composition API for better code organization
3. **Handle events properly**: Use proper event handlers for component interactions
4. **Customize theme**: Use theme variables for customization
5. **Follow design specs**: Follow Element Design specifications
6. **Use TypeScript**: Leverage TypeScript for better type safety
