### 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
