Ember 2.1.0 render partial if index page else another partial

In my templates/application.hbs I would like to be able to set a condition to check if it is my index page I render a navigation for it, else it would render another set of navigation for in-app pages. The same for my footer. What is the best way to check this? Also, whether a user is login or not doesn't matter.

My research has lead to outdated code or convention. I'm also completely new to Ember so any help would be very much appreciated.
