-// - If not installed, prepare to start install by checking network online

-// - If network gets online, start to install the app from web store;
+// - Attempts to load oauth token file. Stores the loaded tokens in
+//   |auth_params_|.
+// - Initialize token service and inject |auth_params_| if needed.
+// - Initialize network if app is not installed or not offline_enabled.
+// - If network is online, install or update the app as needed.
+// - After the app is installed/updated, launch it and finish the flow;
 // Report OnLauncherInitialized() or OnLaunchFailed() to observers:
 // - If all goes good, launches the app and finish the flow;
