## Best Practices

- **Clarity over cleverness**: Use simple language, avoid jargon
- **Show working examples**: Provide complete, runnable code samples
- **Structure logically**: Use clear headings and hierarchy
- **Keep it DRY**: Link to detailed docs instead of repeating information
- **Update regularly**: Documentation is part of the feature, not an afterthought
- **Test examples**: Ensure all code examples actually work
- **Include troubleshooting**: Document common issues and solutions
