Wikipedia Draft:SerenityOS

SerenityOS is a Unix-like opensource operating system for the x86 computer architecture. The project is started as a hobby by the Swedish programmer Andreas Kling. He wanted to learn how to create operating systems since he never studied them before.

As of 2021, the source of SerenityOS is freely available on Github.

History
The SerenityOS project started in 2019. Kling and other developers are still working on the software regularly. The aim of the Serenity project is to provide a modern operating system, that is created on top of a Unix-like core, with a '90s user interface.
