The .vim folder holds all the plugins referenced in .vimrc using the vim 8 packages (:help packages). These plugins are brought in as git submodules.
git clone https://github.com/mikewim/dotfiles.git
cd dotfiles
git submodule init
git submodule update
The zsh setup also expects oh-my-zsh to be in the home directory. Run this to download oh-my-zsh:
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
You can now copy whichever files you like into your home directory to use.
