out of box experience that provides sane defaults with minimal effort to get to working mode

Good description of what Omarchy really is. It's for two groups of people:

1/ (biggest group by far) People who are new to Linux on the desktop and, to a lesser extent, want to get out of the macOS ecosystem

2/ Power users who run Arch btw, and have probably installed, configured, partitioned, and encrypted Arch without the installer script at least a few times and now want a sane default Arch + Hyprland install with sane defaults and a production-grade environment in just a few minutes
