Recommended that you use vundle to install. Here is what the start of my vimrc looks like:
set nocompatible
filetype off
set rtp+=~/.vim/bundle/vundle
call vundle#rc()
Bundle 'gmarik/vundle'
""" ...
Bundle 'clord/vim-insfile'
Bundle 'clord/vim-bookmaster'
Bundle 'clord/vim-scenario'
" :BundleInstall will ensure these are all installed, if vundle is available
syntax enable " Must come after the Bundle commands so that syntax highlighting is available
filetype plugin indent on
:BundleInstall will install from github.
