Embed ember application in another ember application

I am having a simple ember application and I need to embed this into another ember application . How can I do this embedding ?

I have not use it yet but take a look at GitHub - ember-engines/ember-engines: Composable Ember applications for ambitious user experiences

iframes! Yup, it’s been done, and it works reasonably well. You can use GitHub - krakenjs/post-robot: Cross domain post-messaging on the client side using a simple listener/client pattern. to communicate between the apps.
