2, plug-in management
Choose Vim-plug,vim-plug is Korean Junegunn (Junegunn Choi) wrote, the fastest plug-in manager, whether it is the update, installation, are all concurrent (https://github.com/junegunn/vim-plug ) 。
Download the Vim-plug in the user directory and put it in the AutoLoad directory:

        curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Execute the above command, and then create a new plugged directory under the. Vim directory to place the plug-in, and finally the. Vim directory has a directory of autoload and plugged two.

3, configuration. VIMRC
