This is my personal vim setup. To install it in a UNIX environment, clone the repo and create symlinks to the required files from in your home directory as shown below.
ln -s /path/to/vimrc ~/.vimrc
ln -s /path/to/gvimrc ~/.gvimrc
ln -s /path/to/vim ~/.vim
All plugins are managed by vundle and will not exist the first time vim is started therefore you will likely see some error messages. To install the plugins from inside vim run:
:BundleInstall
Now restart vim to be on the safe side. Happy editing!
