Is there documentation for the Concierge Browser?

We are trying to migrate our mobile retail applications to the Concierge and having lots of troubles including rendering issues with dynamic drawing of divs and the ability to use the scanner.


Is this type of application supported on the Concierge Browser or do we need to develop a RhoMobile or PhoneGap application to work on this platform?


Also is there any documentation available for the Concierge Browser?
