YiffOS is a GNU/Linux distro made (mainly) by two people named (according to their Gitlab) Husky and Evie.
The development has mainly stop since around 2 months ago, but it does still install and uses basic programs.
Support for anything, really, is nonexistent. Besides gnome and it's packages, the only way to get a desktop is to compile one from source.
