Kiro is an Arch Linux-based distribution with the goal of being an intuitive and customisable ISO image builder. It provides a simple way to build a custom Arch-based installation medium with a choice of packages, settings and scripts. Kiro uses the Xfce desktops, includes the Calamares system installer, and has a modular structure. 

Kiro is a minimal, flexible, and fully customizable Arch-based ISO project built on top of ArcoLinux.
It aims to give users full control over their system by providing clean scripts and a modular structure for building their own customized ISO.
The default configuration includes systemd-boot, EXT4 filesystem, SDDM display manager, and two desktop environments XFCE and chadwm.
It is designed for power users and developers who want a base to build their personalized setups, rather than a fully loaded “out-of-box” distro.
The build process is transparent, reproducible, and script-driven. The source code, build scripts, and configurations are all version controlled and open.
It also serves as the foundation for Buildra, another custom distro project that uses Kiro as a blueprint.
