Shells are a pretty personal thing and we all like ours a little bit different than anybody else's. my setup is still pretty basic and uses oh my zsh and (for now) a pretty basic vimrc.
to install my basic setup, clone this repo into your root directory and rename it .shell and then copy the .zshrc and .vim/.vimrc files to your root directory. After you copy those files into your root, use zs to source your new .zshrc file.
create a symlink for nvim at ~/.config/nvim for the nvim directory in dotfiles. this way Dein will handle all the plugins for nvim.
