## 📋 Quick Start Checklist

### Using Hooks
- [ ] Read hook documentation
- [ ] Import the hook you need
- [ ] Use in your component
- [ ] Test the functionality

### Creating JSON Pages
- [ ] Read JSON orchestration guide
- [ ] Create JSON schema file
- [ ] Define data sources
- [ ] Build component tree
- [ ] Add actions
- [ ] Test with PageRenderer

### Migrating Components
- [ ] Identify large component
- [ ] Extract business logic to hooks
- [ ] Split into smaller components
- [ ] Create JSON schema (if applicable)
- [ ] Test thoroughly
- [ ] Remove old code

---

## 🎯 Key Concepts Summary

### Hooks
- **Purpose:** Extract and reuse business logic
- **Size:** All under 150 LOC
- **Location:** `/src/hooks/`
- **Examples:** useArray, useCRUD, useSearch, useDialog, useForm

### JSON Orchestration
- **Purpose:** Define pages without code
- **Format:** JSON schema files
- **Location:** `/src/config/pages/`
- **Benefits:** Rapid prototyping, easy testing, no rebuilds

### Component Size
- **Target:** Under 150 LOC
- **Strategy:** Extract logic to hooks
- **Focus:** Presentation only
- **Benefits:** Readable, maintainable, testable

---
