This is my very much personal repo for my vim dot files. I use it to easily set up a new machine

git clone <url> ~/.vim

ln -s .vim/vimrc .vimrc

ln -s .vim/gvimrc .gvimrc

git submodule add <url> <folder>

git submodule init

git submodule update

git submodule foreach git pull origin master

There is not efficient way to remove a submodule

• first step is remove references to the submodule in .gitmodules and .git/config.
• Then git rm --cached .vim/bundle/fugitive
