Documentation Patch for Save As Draft

I just installed this module and after reading the documentation, still struggled where to find how to activate for any given content type. I finally found where it was after about 10 minutes.

Maybe I'm thick but it seemed like the docu could have been more specific so I rolled a patch. This is my first patch submitted to Drupal.org so I hope it's ok. Let me know if you need me to refine it anymore. cheers, thanks. :)
