Omarchy OS: How is Omarchy different from a standard Arch Linux installation?

Omarchy starts with Arch Linux and adds a ready-to-use Hyprland desktop, apps, themes, shortcuts, and setup tools.

A standard Arch installation lets you choose and assemble those pieces yourself. Omarchy supplies an opinionated configuration so you can begin using a complete desktop after installation. It still uses Arch packages and leaves user configuration files available for changes.
