     The index of a delegate is exposed as an accessible \c index property in the delegate.
     Properties of the model are also available depending upon the type of \l {qmlmodels}{Data Model}.

     A Repeater item owns all items it instantiates. Removing or dynamically destroying
     an item created by a Repeater results in unpredictable behavior.
 
-    Note that if a repeater is
-    required to instantiate a large number of items, it may be more efficient to
-    use other view elements such as ListView.
 
-    \note Repeater is \l {Item}-based, and can only repeat \l {Item}-derived objects. 
-    For example, it cannot be used to repeat QtObjects.
+    \section2 Considerations when using Repeater
+
+    The Repeater element creates all of its delegate items when the repeater is first
+    created. This can be inefficient if there are a large number of delegate items and
+    not all of the items are required to be visible at the same time. If this is the case,
+    consider using other view elements like ListView (which only creates delegate items 
+    when they are scrolled into view) or use the \l {Dynamic Object Creation} methods to 
+    create items as they are required.
+
+    Also, note that Repeater is \l {Item}-based, and can only repeat \l {Item}-derived objects. 
+    For example, it cannot be used to repeat QtObjects:
     \badcode
     Item {
         //XXX does not work! Can't repeat QtObject as it doesn't derive from Item.
