## 🚀 How to Get Started

### Option 1: Quick Setup (Recommended)

#### Windows:
```powershell
cd scripts
.\setup.ps1
```

#### Linux/Mac:
```bash
chmod +x scripts/setup.sh
./scripts/setup.sh
```

### Option 2: Manual Setup

#### Development Mode (Database in Docker, App on Host)
```bash
# 1. Copy environment file
cp env.example .env

# 2. Edit .env and set NEXTAUTH_SECRET and IP_SALT
# Generate with: openssl rand -base64 32

# 3. Install dependencies
npm install

# 4. Start database services
npm run docker:dev

# 5. Run migrations
npm run db:migrate

# 6. Seed database
npm run db:seed

# 7. Start development server
npm run dev
```

#### Production Mode (Full Stack in Docker)
```bash
# 1. Copy and configure environment
cp env.example .env
# Edit .env with your settings

# 2. Build and start
npm run docker:prod

# 3. Run migrations
docker-compose exec web npx prisma migrate deploy

# 4. Access at http://localhost:3050
```
