Navigation and Routing Tutorials don't match up + missing scratchpad code



I’m fairly new to ionic and tried following the navigation tutorials (pt1 + pt2) located at:

I’m getting confused, because in part 1 you don’t use nested / abstract views, but in part 2 it is assumed that there is some sort of app view.

Here are the routes at the end of part 1:
state: ‘home’, url: ‘/home’, templateUrl: 'home.html’
state: ‘help’, url: ‘/help’, templateUrl: ‘help.html’

In part 2 you assume there’s was a state ‘app.home’ and change it to ‘app.todos’. I understand, but no matter what I change, I just can’t follow up all the way to the end.

The fact that the full code is missing at the end makes it harder: In both tutorials it says at the end: Try this tutorial out below in the Scratchpad, but nothing shows up (Chrome Version 44.0.2403.155 (64-bit), OS X).

Could you please revise the tutorials?
