First, thanks to http://usevim.com/

#Add a plugin (sample)

• cd ~/.vim
• git submodule init
• git submodule add git://github.com/tpope/vim-fugitive.git bundle/vim-fugitive
• Eventually modify and copy your .vimrc here :
  • vim ~/.vimrc
  • cp ~/.vimrc ~/.vim/.vimrc
• git commit -m 'Added vim-fugitive'
• git push

#Download vim plugins and config it

• git clone https://github.com/ger-benjamin/personnal_vim_plugins.git ~/.vim
• cd ~/.vim
• git submodule init
• git submodule update
• Eventually restore vimrc from github repository
  • cp .vimrc ~/.vimrc

#Miscaleaneous Thinks that the pathogen plugin itself is maybe out of date :-)
