 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.
 
+### Custom styling
+Basic styling can be done by choosing the active and inactive step colors. 
+There are some additional properties which can be changed directly from StepperLayout's attributes e.g. the background of bottom navigation buttons (see <a href="#stepperlayout-attributes">StepperLayout attributes</a>)
+For advanced styling you can use `ms_stepperLayoutTheme` StepperLayout's attribute and provide your custom style to be used.
+See 'Custom StepperLayout theme - progress bar' and 'Custom StepperLayout theme - Tabs dark' in the sample app for an example.
+
 ### 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.
