charleX OS

CharleX is a simple operating system. The kernel is written in C. I am still working on the source code to improve the kernel with many new features. My goal is to create a free, open-source operating system similar to Linux and FreeBSD. You can support us by contributing and improving the code for this project or by giving it a star.
