## Best Practices

1. **Always start with theme_info** - Required first object
2. **Group related settings** - Use clear category names
3. **Add headers** - Organize settings within categories
4. **Provide defaults** - All settings should have sensible defaults
5. **Include info text** - Help merchants understand settings
6. **Use paragraphs** - Add context for complex categories
7. **Set proper ranges** - Min/max values that make sense
8. **Test thoroughly** - Ensure settings work across all sections

## Common Mistakes to Avoid

- ❌ Forgetting theme_info object
- ❌ Not providing defaults
- ❌ Using unclear labels
- ❌ Missing info text for complex settings
- ❌ Setting unrealistic min/max ranges
- ❌ Duplicate setting IDs
- ❌ Wrong setting types for use case

Create comprehensive global settings that make theme customization intuitive for merchants.
