+
+---
+
+## 🚀 Quick Start
+
+### Automated Setup (Recommended)
+
+```bash
+./setup.sh
+```
+
+### Manual Setup
+
+#### 1. Install Dependencies
+
+**Frontend:**
+
+```bash
+cd frontend
+npm install
+```
+
+**Backend:**
+
+```bash
+cd backend
+npm install
+```
+
+#### 2. Configure Environment
+
+**Backend:** Update `backend/.env`:
+
+```env
+PORT=3000
+DATABASE_URL="postgresql://user:password@localhost:5432/skyartshop"
+JWT_SECRET=your-secret-key
+CORS_ORIGIN=http://localhost:5173
+```
+
+**Frontend:** Update `frontend/.env`:
+
+```env
+VITE_API_URL=http://localhost:3000/api
+```
+
+#### 3. Set Up Database
+
+```bash
+cd backend
+npx prisma generate
+npx prisma migrate dev
+```
+
+#### 4. Start Development Servers
+
+**Terminal 1 - Backend:**
+
+```bash
+cd backend
+npm run dev
+# Runs on http://localhost:3000
+```
+
+**Terminal 2 - Frontend:**
+
+```bash
+cd frontend
+npm run dev
+# Runs on http://localhost:5173
+```

+
+## 📝 How to Add a New Feature
+
+See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) for a complete step-by-step guide on adding the "Wishlist" feature.
+
+### Quick Overview

+3. Create controller (request handler)
+4. Add routes
+5. Add validation
+
+**Frontend:**
+
+1. Add TypeScript types
+2. Create API client methods
+3. Create custom hook (optional)
+4. Use in components
