# Kilian — a systems-programming focused layer on top of Void Linux.
# Turns a fresh Void install into a box ready to build, break, and
# understand low-level software.
#
#   Usage (on a fresh Void install, as root):
#     ./install.sh
#
# Kilian is not an OS. It's an opinion: Void underneath, a curated
# toolchain on top, aimed at people who want to learn Linux from the
# inside — not hide from it.
