+- a dapp should be defined on info.json
+- a dapp compose of 3 main components.
+
+Service - a  component that runs on background and provides services that can be consumed by other dapps.
+
+Activity - a component that would only run when started by user or another dapp. Usually this component contain UI to handle user operations.
