How do I access Ember.js API documentation?

I'm using an older version of Ember (two older versions in fact) and I'd like to view the API docs for a version that's older than 2.x, the versions I'm using are Ember v1.12.0 and v1.10.0.

I already know how to access the older guides using the dropdown menu but there's no menu like that for the API docs.

Is there a way to get this online or can I generate the API docs locally for my particular versions of Ember?
