  def caveats; <<-EOS.undent
    In the interest of allowing you to run `nginx` without `sudo`, the default
    port is set to localhost:8080.

    If you want to host pages on your local machine to the public, you should
    change that to localhost:80, and run `sudo nginx`. You'll need to turn off
    any other web servers running port 80, of course.

    You can start nginx automatically on login running as your user with:
      mkdir -p ~/Library/LaunchAgents
      cp #{plist_path} ~/Library/LaunchAgents/
      launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Though note that if running as your user, the launch agent will fail if you
    try to use a port below 1024 (such as http's default of 80.)
