"BoredOS is now in a Beta stage as i have brought over all apps from boredkernel and have made the DE a lot more usable and stable.\n"
"## Boredkernel is now BoredOS!\n"
"Boredkernel will from now on be deprecated as it's core became too messy. I have built a less bloated kernel and wrote a DE above it, which is why it is now an OS instead of a kernel (in my opinion).\n\n"
"Bored Kernel is a simple x86_64 hobbyist operating system.\n"
"It features a DE (and WM), a FAT32 filesystem, customizable UI and much much more!\n\n"
"## Features\n"
"- Bored WM\n"
"- Fat 32 FS\n"
"- 64-bit long mode support\n"
"- Multiboot2 compliant\n"
"- Text editor\n"
"- IDT\n"
"- Ability to run on actual x86_64 hardware\n"
"- CLI\n\n"
"## Prerequisites\n\n"
"To build BoredOS, you'll need the following tools installed:\n\n"
"- **x86_64 ELF Toolchain**: `x86_64-elf-gcc`, `x86_64-elf-ld`\n"
"- **NASM**: Netwide Assembler for compiling assembly code\n"
"- **xorriso**: For creating bootable ISO images\n"
"- **QEMU** (optional): For testing the kernel in an emulator\n\n"
"On macOS, you can install these using Homebrew:\n"
"```sh\n"
"brew install x86_64-elf-binutils x86_64-elf-gcc nasm xorriso qemu\n"
"```\n\n"
"## Building\n\n"
"Simply run `make` from the project root:\n\n"
"```sh\n"
"make\n"
"```\n\n"
"This will:\n"
"1. Compile all kernel C sources and assembly files\n"
"2. Link the kernel ELF binary\n"
"3. Generate a bootable ISO image (`boredos.iso`)\n\n"
"The build output is organized as follows:\n"
"- Compiled object files: `build/`\n"
"- ISO root filesystem: `iso_root/`\n"
"- Final ISO image: `boredos.iso`\n\n"
"## Running\n\n"
"### QEMU Emulation\n\n"
"Run the kernel in QEMU:\n\n"
"```sh\n"
"make run\n"
"```\n\n"
"Or manually:\n"
"```sh\n"
"qemu-system-x86_64 -m 2G -serial stdio -cdrom boredos.iso -boot d\n"
"```\n\n"
"### Running on Real Hardware\n\n"
"*Warning: This is at YOUR OWN RISK. This software comes with ZERO warranty and may break your system.*\n\n"
"1. **Create bootable USB**: Use [Balena Etcher](https://www.balena.io/etcher/) to flash `boredos.iso` to a USB drive\n\n"
"2. **Prepare the system**:\n"
" - Enable legacy (BIOS) boot in your system BIOS/UEFI settings\n"
" - Disable Secure Boot if needed\n\n"
"3. **Boot**: Insert the USB drive and select it in the boot menu during startup\n\n"
"4. **Tested Hardware**:\n"
" - HP EliteDesk 705 G4 DM (AMD Ryzen 5 PRO 2400G, Radeon Vega)\n"
" - Lenovo ThinkPad A475 20KL002VMH (AMD Pro A12-8830B, Radeon R7)\n\n"
"## Project Structure\n\n"
"- `src/kernel/` - Main kernel implementation\n"
" - `boot.asm` - Boot assembly code\n"
" - `main.c` - Kernel entry point\n"
" - `*.c / *.h` - Core kernel modules (graphics, interrupts, filesystem, etc.)\n"
" - `cli_apps/` - Command-line applications\n"
" - `wallpaper.ppm` - Default desktop wallpaper\n"
"- `build/` - Compiled object files (generated during build)\n"
"- `iso_root/` - ISO filesystem layout (generated during build)\n"
"- `limine/` - Limine bootloader files (downloaded automatically)\n"
"- `linker.ld` - Linker script for x86_64 ELF\n"
"- `limine.conf` - Limine bootloader configuration\n"
"- `Makefile` - Build configuration and targets\n\n"
