## Quick Start

### Prerequisites

- Python 3.8+
- Node.js 16+
- Git

### Installation

1. Clone the repository:
```bash
git clone <repository-url>
cd git
```

2. Install backend dependencies:
```bash
cd backend
pip install -r requirements.txt
```

3. Install frontend dependencies:
```bash
cd ../frontend
npm install
```

### Initialization

1. Create environment configuration:
```bash
cp .env.example .env
```

2. Edit `.env` with your configuration:
```bash
# Generate a secure encryption key (32 bytes, base64 encoded)
python -c "import base64, os; print(base64.b64encode(os.urandom(32)).decode())"

# Generate a secure API token
python -c "import secrets; print(secrets.token_urlsafe(32))"
```

3. Initialize the database:
```bash
cd backend
python init_db.py
```

### Build and Run

#### Option 1: Using the start script (Linux/Mac)
```bash
./start.sh
```

#### Option 2: Manual startup

1. Build the frontend:
```bash
cd frontend
npm run build
```

2. Start the backend server:
```bash
cd ../backend
python -m app.main
```

Or using uvicorn directly:
```bash
cd backend
uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
```

3. Access the application:
   - Web UI: http://localhost:8000
   - API Documentation: http://localhost:8000/api/docs
   - ReDoc: http://localhost:8000/api/redoc

## API Documentation

### Authentication

All API endpoints require authentication via the `X-API-Token` header:

```bash
curl -H "X-API-Token: your-api-token" http://localhost:8000/api/servers
```

### Main Endpoints

#### Status
- `GET /api/status` - Get system status

#### SSH Keys
- `GET /api/ssh-keys` - List all SSH keys
- `POST /api/ssh-keys` - Create a new SSH key
- `GET /api/ssh-keys/{key_id}` - Get SSH key details
- `PUT /api/ssh-keys/{key_id}` - Update SSH key
- `DELETE /api/ssh-keys/{key_id}` - Delete SSH key

#### Servers
- `GET /api/servers` - List all servers
- `POST /api/servers` - Add a new server
- `GET /api/servers/{server_id}` - Get server details
- `PUT /api/servers/{server_id}` - Update server
- `DELETE /api/servers/{server_id}` - Delete server
- `POST /api/servers/{server_id}/sync` - Trigger server sync

For detailed API documentation, visit `/api/docs` when the server is running.

## Development Setup

### Backend Development

1. Install development dependencies:
```bash
cd backend
pip install -r requirements.txt
```

2. Run tests:
```bash
pytest
```

3. Run with auto-reload:
```bash
uvicorn app.main:app --reload
```

### Frontend Development

1. Start development server:
```bash
cd frontend
npm run dev
```

2. Build for production:
```bash
npm run build
```

3. Preview production build:
```bash
npm run preview
```
