I need clarity of facebook canvas app authorization

Question

It's not clear to me from the documentation how it's supposed to work. I know that if I'm using the javascript sdk and have an external site that implements facebook login/registration, I can use the facebook plug in that handles that; but I have a canvas app. If I want to have a user authorize my app as soon as they land on my home page. What does that code look like? I'll be using the javascript sdk.
