+This sample has 3 components: the home screen, the podcast details screen, and the player screen
 
 The home screen is split into sub-screens for easy re-use:
 
-- __Home__, allowing the user to see their followed podcasts (top carousel), and navigate between 'Your Library' and 'Discover'
+- __Home__, allowing the user to see their subscribed podcasts (top carousel), and navigate between 'Your Library' and 'Discover'
 - __Discover__, allowing the user to browse podcast categories
 - __Podcast Category__, allowing the user to see a list of recent episodes for podcasts in a given category.
 
-The player screen displays media controls and the currently "playing" podcast (the sample currently doesn't actually play any media).
+Multiple panes will also be shown depending on the device's [window size class][wsc].
