==> Caveats
You need to manually run setup_dirs to create directories required by nodebrew:
  /usr/local/opt/nodebrew/bin/nodebrew setup_dirs

Add path:
  export PATH=$HOME/.nodebrew/current/bin:$PATH

To use Homebrew's directories rather than ~/.nodebrew add to your profile:
  export NODEBREW_ROOT=/usr/local/var/nodebrew

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

zsh completions have been installed to:
  /usr/local/share/zsh/site-functions
