vkg.vim is the vim plugin to control vkg directly from Vim.
vkg.vim depends on vkg. If you haven't vkg installed in your system yet, install it:
npm install -g coffee-script #just in case you have not installed it yet
npm install -g vkg
Temporal recomended installation method:
cd ~/.vim/bundle
git clone https://github.com/pepegar/vkg.vim.git
vkg.vim is waiting for review at Vimawesome, but I expect to have it approved in the next days, so installing will be as easy as
vkg install vkg-vim
