 # MetalOS
-A OS that is not linux, not bsd and not windows. Ground up OS with just enough bespoke kernel to run a QT6 hello world full screen app on AMD64 with Radeon RX 6600 GPU., UEFI native
 
-- Might use Linux kernel only as inspiration for driver code
-- Some changes might be required to QT6 - We can git clone this.
+A minimal operating system built from the ground up to run QT6 applications on AMD64 hardware with Radeon RX 6600 GPU and UEFI boot.
+
+**Not Linux. Not BSD. Not Windows.** Just enough OS to run a QT6 Hello World full-screen application.
+
+## Project Status
+
+🚧 **In Development** - Phase 1 Complete (Foundation)
+
+Currently: Project structure, documentation, and skeleton code in place.
+
+## What is MetalOS?
+
+MetalOS is a **minimal, purpose-built operating system** with a single goal: demonstrate that you can build a custom OS from scratch to run modern GUI applications (specifically QT6).
+
+### Key Features
+
+- ✅ **UEFI Native**: Modern boot via UEFI (no legacy BIOS)
+- ✅ **AMD64 Architecture**: 64-bit x86 processor support
+- ✅ **Radeon RX 6600 GPU**: Hardware-specific graphics support
+- ✅ **QT6 Framework**: Full QT6 widget support
+- ✅ **Minimal Design**: Only what's necessary, nothing more
+
+### What's Included
+
+- **UEFI Bootloader**: Initializes hardware and loads kernel
+- **Minimal Kernel**: Memory management, scheduling, interrupts
+- **GPU Driver**: Radeon RX 6600 specific (inspired by Linux amdgpu)
+- **HAL**: Hardware abstraction for PCI, input devices
+- **User Space**: Minimal C++ runtime for applications
+- **QT6 Port**: QT6 framework ported to MetalOS
+- **Hello World App**: Full-screen QT6 demonstration application
+
+### What's NOT Included
+
+- ❌ Multi-user support
+- ❌ Command line / shell
+- ❌ Networking stack
+- ❌ File systems (app embedded in boot image)
+- ❌ POSIX compatibility
+- ❌ Security features (this is a demo/learning project)
+- ❌ Support for other hardware
+- ❌ Multiple applications (single app only)
+
+## Quick Start
+
+### Prerequisites
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install build-essential nasm qemu-system-x86 ovmf
+
+# macOS
+brew install nasm qemu
+```
+
+You'll also need a cross-compiler. See [docs/BUILD.md](docs/BUILD.md) for details.
+
+### Building
+
+```bash
+# Clone the repository
+git clone https://github.com/johndoe6345789/MetalOS.git
+cd MetalOS
+
+# Build everything
+make all
+
+# Create bootable image
+make image
+
+# Test in QEMU
+make qemu
+```
+
+### Testing on Hardware
+
+⚠️ **WARNING**: This is experimental software. Test on non-production hardware only.
+
+See [docs/BUILD.md](docs/BUILD.md) for instructions on creating a bootable USB drive.

+
+## Why?
+
+**Learning**: Building an OS from scratch is the ultimate systems programming education.
+
+**Minimal Design**: Modern OSes are complex. This project asks: "What's the absolute minimum needed for a GUI application?"
+
+**Custom Hardware**: Show that you can optimize an OS for specific hardware instead of supporting everything.
+
+**QT6 Demo**: Prove that modern application frameworks can run on custom OS implementations.
+
+## Technology Stack
+
+- **Language**: C for kernel, C++ for applications
+- **Boot**: UEFI
+- **Architecture**: AMD64 (x86-64)
+- **Graphics**: Direct framebuffer + Radeon RX 6600
+- **GUI**: QT6 (Core, Gui, Widgets)
+- **Build**: GNU Make, GCC cross-compiler
+
+## Inspiration
+
+- **Linux Kernel**: For driver implementations (especially GPU)
+- **SerenityOS**: For clean, minimal OS design
+- **TempleOS**: For single-purpose OS philosophy
+- **Redox OS**: For Rust-based OS architecture (though we use C/C++)
+
+## Contributing
+
+This is primarily a learning/demonstration project, but contributions are welcome!
+
+**Guidelines**:
+- Keep it minimal - every feature must justify its existence
+- Document your changes
+- Follow existing code style
+- Test on QEMU before submitting
+
+See [docs/DEVELOPMENT.md](docs/DEVELOPMENT.md) for details.
