  def caveats

    Docroot is: #{HOMEBREW_PREFIX}/var/www

    The default port has been set to 8080 so that nginx can run without sudo.

    If you want to host pages on your local machine to the wider network you
    can change the port to 80 in: #{HOMEBREW_PREFIX}/etc/nginx/nginx.conf

    You will then need to run nginx as root: `sudo nginx`.
