Do I need to add any additional ruleset into my application for enabling my application for mobile devices? Also, there are several types of rules which cannot be used for offline cases, is there some mobile SDK available for development to enable the those types of rules for offline support(Which are not supported OOTB)?
For branding purpose, it specifies some pega mobile client licence is required and also requires a build server. Is there a PDN doc specifying the complete procedure for the same?
There is a 10 minute video/course on Pega Academy that will provide an overview of Pega Mobility solution. From the PDN go to Pega Academy>My self Study Once in PA in the left hand pane select "Course Library". Under Pega Platform you will find the Pega Mobile course in the third list on the screen.
This PDN landing page is also a great place to get started:
