        Change the page size of this collection.
 
+       Under most if not all circumstances, you should call this method to
+       change the page size of a pageable collection because it will keep the
+       pagination state sane. By default, the method will recalculate the
+       current page number to one that will retain the current page's models
+       when increasing the page size. When decreasing the page size, this method
+       will retain the last models to the current page that will fit into the
+       smaller page size.
+
+       If `options.first` is true, changing the page size will also reset the
+       current page back to the first page instead of trying to be smart.
+
        For server mode operations, changing the page size will trigger a #fetch
        and subsequently a `reset` event.
