emerald is a minimalistic Unix-like operating system kernel developed for x86_64 systems, focused on being lightweight, modular, and understandable. Written in C and assembly, emerald serves as a learning tool for OS enthusiasts who want to explore kernel design from scratch. It includes basic components such as multitasking, paging, interrupts, and system calls, while maintaining a clear and concise codebase. Emerald is a strong starting point for building more complex systems or experimenting with new OS features.
