Deeplink to Ember app from outside

How can I deeplink to my Ember app from outside ? Say I want to deeplink to within my ember route (mainPage\deepRoute)

So when user clicks on the external link (not part of my Ember app), he is directly taken to mainPage\deepRoute

How will I code such a link ?

I assume by default the Ember application template would be rendered, but I want to direct route to some other link/template ?
