Sorry for being late to the discussion, but I'd like to share my dotfiles and setup script that I use for my Debian Testing machines.
https://salsa.debian.org/samueloph/dotfiles I just updated the README.md to explain the high level of it. In summary, this is what I use to setup vim, atom, i3, bashrc, powerline and my packaging tools. Regards, -- Samuel Henrique <samueloph>
