    For Bash or Zsh, put something like this in your $HOME/.bashrc or $HOME/.zshrc:
      . `brew --prefix`/etc/profile.d/z.sh

    ZSH USERS BACKWARD COMPATIBILITY WARNING:
     z now handles 'precmd' set up for zsh. z (<=1.3) users using zsh should
     remove the precmd function that was described in the installation
     instructions for previous versions.

    In short, this:
      . /path/to/z.sh
      function precmd () {
       _z --add "$(pwd -P)"
      }

    should now be:
      . `brew --prefix`/etc/profile.d/z.sh
    EOS
  end
