If you like what you see here and want to use it in your configuration, I recommend forking it, as this is basically a personal configuration repo, so it's unlikely that I'll accept pull requests changing configuration parameters. I'll take PRs fixing or improving my code though :)
Clone it in the configuration directory and use make bootstrap:
% git clone https://github.com/fsouza/vimfiles.git ${HOME}/.config/nvim
% make -f ${HOME}/.config/nvim/Makefile bootstrap
