How to embed one ember application in another ember application?

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

You can't embed ember app inside another ember app. but you can embed ember app in other frameworks or websites.(I may be wrong, in my earlier attempt I failed)
But you have got few options to consider,
1. You can consider writing ember engine
2. You can write addon and use it in your ember app
