## ✨ Features

- **5-Level Permission System** - Granular access control (User, Admin, God, SuperGod, SystemRoot)
- **Multi-Tenant Architecture** - Built-in support for tenant isolation
- **Declarative Configuration** - Define features in JSON, not code
- **Lua Scripting** - Dynamic business logic without recompilation
- **Database-Driven** - All configuration stored and managed in database
- **Package System** - Modular, reusable feature packages
- **Type-Safe** - Full TypeScript support throughout
- **CI/CD Ready** - Automated testing, linting, and deployment workflows

## 🚀 Quick Start

### Prerequisites

- Node.js 18+
- npm or yarn
- Docker (optional, for deployment)

### Development Setup

```bash
# Clone repository
git clone <repo>
cd metabuilder

# Install dependencies
npm install

# Set up database
npm run db:generate
npm run db:push

# Start development server
npm run dev
```

Visit `http://localhost:5173` to access the application.

### Build for Production

```bash
npm run build
npm run preview  # Preview production build locally
```

## 📐 Architecture

MetaBuilder uses a **5-level permission system**:

```
SuperGod (Level 5) - System administrator, full access
   ↓
God (Level 4) - Power user, can modify system configuration
   ↓
Admin (Level 3) - Tenant administrator, manage users and data
   ↓
User (Level 2) - Regular user, standard data access
   ↓
Guest (Level 1) - Read-only access (not implemented)
```

### Key Components

- **Prisma ORM** - Type-safe database queries
- **React + TypeScript** - Modern UI framework
- **Vite** - Fast build tool
- **Tailwind CSS** - Utility-first CSS framework
- **Lua (Fengari)** - Embedded scripting

For detailed architecture information, see [Architecture Documentation](./docs/architecture/).
