+# Manual setup for labtops
+
+## Poor man’s setup
+
+### Intro
+
+- download newest nixos setup
+- write to USB stick
+- boot live system
+
+### Install vanilla nixos
+
+- use parted to setup msdos table (mktable) & full-disk partition (mkpart 0% 100%)
+- mkfs.ext4 -L /dev/sda1
+- mount /dev/disk/by-label/labtop /mnt
+- nixos-generate-config --root mnt, comment out a few things in /mnt/etc/nixos/configuration.nix
+- nixos-install
+- set temporary root password (123456), will be overwritten by vuizvui
+- reboot
+
+### Install vuizvui
+
+- boot, login as root
+- follow “installing a machine” documentation from vuizvui wiki
