The document discusses building government apps that are usable, easy to share and collaborate on. It recommends collaborating on app development openly across agencies and countries. Examples are given of open source platforms like Drupal and GitHub that can be used to build apps. Specific guidance is provided on how to create apps using Drupal modules and features, ensure interoperability, include configuration forms and demo content, and distribute the apps through app marketplaces and one's own server. The goal is to encourage anyone to start building apps to solve problems in an open and shareable way.
