(Re)move ~/.vim and ~/.vimrc if you have them already, and run:
git clone git://github.com/jlabarbera11/vim-config.git ~/.vim
cd ~/.vim
git submodule update --init
ln -s ~/.vim/vimrc ~/.vimrc
cd ~/.vim/bundle
git submodule add git://github.com/tpope/vim-fugitive.git bundle/vim-fugitive
cd ~/.vim/bundle
rm -rf vim-fugitive
