The code represents my custom Arch Linux setup. It is written in Ansible and allows to fully automate the setup of a new machine. It consists all customizations that are needed to be done from scratch to set up new system (including file configuration changes, disk format, package installation and dotfiles).
More information can be found on blog post.
