-          An application sends the user to Connect. The user chooses one
-          compatible collection and approves exact actions. The application
-          receives a collection-bound connection; local folder paths stay on
-          the user's computer.
+          Start in the app you want to use. mdbase Connect opens when that app
+          needs a collection, shows what it is asking for, and lets you choose
+          the folder or hosted collection it can use.
