        This package contains a compiled release of MetalOS.
        
        ## Contents
        
        - **metalos.img** - Bootable disk image (use with QEMU or write to USB)
        - **bootx64.efi** - UEFI bootloader (standalone)
        - **metalos.bin** - Kernel binary
        - **QEMU_INSTRUCTIONS.md** - Detailed instructions for testing with QEMU on Windows, macOS, and Linux
        - **README.md** - This file
        
        ## Quick Start
        
        ### Testing with QEMU
        
        The easiest way to test MetalOS is using QEMU. See **QEMU_INSTRUCTIONS.md** for detailed setup instructions for your operating system.
        
        **Quick command (Linux/macOS with QEMU and OVMF installed):**
        ```bash
        qemu-system-x86_64 \
          -bios /usr/share/OVMF/OVMF_CODE.fd \
          -drive format=raw,file=metalos.img \
          -m 512M \
          -serial stdio
        ```
        
        **Quick command (Windows with QEMU installed):**
        ```cmd
        "C:\Program Files\qemu\qemu-system-x86_64.exe" ^
          -bios "C:\Program Files\qemu\share\edk2-x86_64-code.fd" ^
          -drive format=raw,file=metalos.img ^
          -m 512M ^
          -serial stdio
        ```
        
        ### Creating a Bootable USB
        
        ⚠️ **WARNING**: This will erase all data on the USB drive!
        
        ```bash
        # Linux/macOS (replace /dev/sdX with your USB device)
        sudo dd if=metalos.img of=/dev/sdX bs=4M status=progress
        sync
        ```
        
        ## System Requirements
        
        - **Architecture**: AMD64 (x86-64)
        - **Boot Mode**: UEFI
        - **Minimum RAM**: 512MB
        - **Target Hardware**: Radeon RX 6600 GPU (for full functionality)
        
        ## Development Status
        
        MetalOS is currently under active development. See the repository for current status and roadmap.
