-Sometimes you might want to have different labels on the Next button on different steps e.g. use the default label on the first few steps,
+### Changing Back/Next button labels per step
+Sometimes you might want to have different labels on the Next and/or Back navigation buttons on different steps e.g. use the default labels on the first few steps,
 but display 'Summary' just before the last page.

 ### Using the same stepper styling across the application

 To get a callback when this button was pressed you need set a ```StepperListener``` and write your own custom return logic in the ```onReturn()``` method to e.g. close the Activity.
 
 ### Using with Views instead of Fragments
-<b>TODO: document</b>
+It is possible to use this library without the need to rely on Fragments.
+To do so you need to use ```AbstractStepAdapter``` instead of ```AbstractFragmentStepAdapter```.
+For an example of how to use it with views please see the sample app.
 
 ### Advanced usage
 For other examples, e.g. persisting state on rotation, displaying errors, changing whether the user can go to the next step, etc. check out the sample app.
