11## About
12
13SerenityOS 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.
14
15Roughly 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.

17You can watch videos of the system being developed on YouTube:

49## How do I read the documentation?
50
51Man pages are available online at [man.serenityos.org](https://man.serenityos.org). These pages are generated from the Markdown source files in [`Base/usr/share/man`](https://github.com/SerenityOS/serenity/tree/master/Base/usr/share/man) and updated automatically.
52
53When running SerenityOS you can use `man` for the terminal interface, or `help` for the GUI.
54
55Code-related documentation can be found in the [documentation](Documentation/) folder.
56
57## How do I build and run this?
58
59See the [SerenityOS build instructions](https://github.com/SerenityOS/serenity/blob/master/Documentation/BuildInstructions.md). Serenity runs on Linux, macOS (aarch64 might be a challenge), Windows (with WSL2) and many other *Nixes with hardware or software virtualization.
