How to change the content of div on the basis of what is selected in the menu

Please bear with me, this question is very crude. I'm new to Ember js, and have got a lotta confusion between views controllers templates routes. I have this basic requirement, to have a menu on the left, with item users, organizations. and a div in the center, As of now, when i click users, i have given a link to /users route. for organizations /organizations route, which is a different template. I want to display them in the centered div. Not sure how to do that. I think it has got something to do with child views, but find myself numb in beginning. I just need help in the workflow of how to achieve this.
