Anyone knows how to configure META?

I tried posting in the META thread but no one answered after 2+ weeks.  Perhaps someone knows what is wrong with my setup?  Here is my post:

I am guessing I don't understand how Kodi/META/my library/add-ons are 'interconnected'?

Is there some kind of data flow diagram of Kodi, data stores, ... somewhere?
