I'm still new to vim and tmux. These configs may not be optimal.

Install fzf in ~/.fzf (or link it there) try <leader>t

Install jshint for syntastic: npm install -g jshint

Make vimproc:

• cd ~/.vim/bundle/vimproc.vim
• make

Install YouCompleteMe:

• brew install cmake / sudo apt-get install build-essential cmake python-dev python3-dev
• cd vim/bundle/YouCompleteMe
• ./install.py --tern-completer
