        This package contains everything needed to deploy the FRP Manager application.
        
        ## Files
        
        - `docker-compose-app.yml` - App deployment configuration
        - `docker-compose-node.yml` - Node deployment configuration  
        - `.env.app.example` - App environment template
        - `.env.node.example` - Node environment template
        - `deploy.sh` - Deployment script
        
        ## Quick Start
        
        ### 1. App Server (VPS)
        ```bash
        # Configure environment
        cp .env.app.example .env
        # Edit .env with your configuration
        
        # Deploy
        docker-compose -f docker-compose-app.yml up -d
        ```
        
        ### 2. Home Server
        ```bash
        # Configure environment  
        cp .env.node.example .env
        # Edit .env with your configuration
        
        # Deploy
        docker-compose -f docker-compose-node.yml up -d
        ```
        
        ## Environment Variables
        
        See the `.env.*.example` files for required configuration.
        
        **Important**: Set matching tokens for `NODE_TOKEN` (app) and `API_TOKEN` (node).
        
        ## Verification
        
        1. Check app: `http://your-vps:3000`
        2. Check node: `http://your-home-server:3001/health`
        3. Test integration via the "Push to Node" button in the web interface
