HydrOS aims to be a simple yet well documented kernel for the x86-64 architecture.

Hydros (that's why OS looks so nice there) is one of the Greek deities associated with water (specially in ancient texts), which is cool. But what is even cooler is the fact the Hydrogen is the first element in the periodic table, which means it is the lightest one.

Depending on your operating system you may need different packages. In case you run build.sh with a problem, simply install the package of the failed command. To build the kernel you need gcc, nasm and the GNU linker (ld). Finally, to build the image you will need xorriso.

• Clone the repository with git clone <url>
• Run build.sh with the build or run options (use the limine option before that if you are building the kernel for the first time)
