    Add the following lines to your bash or zsh config (e.g. ~/.bash_profile):
      if [ -f $(brew --prefix)/bin/liquidprompt ]; then
        . $(brew --prefix)/bin/liquidprompt
      fi

    If you'd like to reconfigure options, you may do so in ~/.liquidpromptrc.
    A sample file you may copy and modify has been installed to
      #{HOMEBREW_PREFIX}/share/liquidprompt/liquidpromptrc-dist

    Don't modify the PROMPT_COMMAND variable elsewhere in your shell config;
    that will break things.
