# SerenityOS

Graphical Unix-like operating system for x86 computers.

[![Build status](https://github.com/SerenityOS/serenity/workflows/Build,%20lint,%20and%20test/badge.svg)](https://github.com/SerenityOS/serenity/actions?query=workflow%3A"Build%2C%20lint%2C%20and%20test")

## About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s \*nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on [my YouTube channel](https://www.youtube.com/c/AndreasKling/).

Sometimes I write about the system on [my github.io blog](https://awesomekling.github.io/).

I'm also on [Patreon](https://www.patreon.com/serenityos) and [GitHub Sponsors](https://github.com/sponsors/awesomekling) if you would like to show some support that way.
