�� A delightful community-driven (with 1,300+ contributors) framework for managing your zsh configuration. Includes 200+ optional plugins (rails, git, OSX, hub, capistrano, brew, ant, php, python, etc), over 140 themes to spice up your morning, and an auto-update tool so that makes it easy to keep up with the latest updates from the community. - robbyrussell/oh-my-zsh
My Note:
In '.vimrc Setup' section, in place of this:
"" only show completion as a list instead of a sub-window
set completeopt-=preview
use this:
"" no preview window after completion
let g:ycm_autoclose_preview_window_after_completion=1
