Impossibly hard to set up in Facebook. Instructions fall short.

I followed the instructions to set up the FB app but then Facebook required all kinds of additional information that is not covered in the step-by-step instructions. What a huge waste of time spending hours to set this up! Apparently, it is not easy to set up at all. My app has to be reviewed and who knows how long that will take or what demands they will come back with. It should not be this hard to enable this plugin.
