  def caveats
    <<-CAVEATS
You need to create a logs folder before you can run NginX. Also, 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 probably change that to localhost:80, and run `nginx` with
`sudo`.
