How to set of Config for RC0 now that ionicbootstrap is gone

As shown here in the docs you can set the config for the entire app or platform but it used ionicbootstap module.

With RC0 ionicbootstap is no longer available so how can we set the config for entire app or platform.

found the answer in the change logs which is quoted blog

Move any Ionic config to the IonicModule.forRoot in app.module.ts. For example, the config should go where it says configObject here: IonicModule.forRoot(MyApp, {configObject}).

The docs need to be updated ASAP
