WMS Remote repository - placing firmware file

Hi, 

Where do the ThinOS firmware files go on the WMS Remote repository?

Was able to get the pkg/App files recognized but not firmware 

WMS 2.0 guide mentions ThinosConfigFiles  folder but when i place the files they don't show up on WMS cloud. Any suggestion?
