If you do a search on let's say 'iReal Pro D.C al Coda' you either get pages with fancy javascript where the information is hidden behind a drop-down popup:

http://www.irealb.com/support/android-manual/

Or then a page like this where the images are missing:

http://www.irealb.com/page3/page11/page10/page10.html

I would recommend that you put generic information such as this for editing in a format that is plain so web search engines could index them and anyone could easily get to it. That or add the links to the MacOSX Help menu.
