I am relatively new to doing development. I have only used it for the addition/removal of columns in objects, and for cleaning up extra versions of Business Processes.

To add business rule you would need to create your custom module where you add the code similar to the one in the article, after that create a replacing schema for MobileApplicationManifestDefaultWorkplace and add the Module to the ModelExtensions. I've found a bit more detailed instruction here:
