+# Component Children
+
+Used to mark where children of instances of this component will be placed.
+
+Any instance of a component that have a **Component Children** placed in its heirarchy will be
+able to have children. These children will appear as though they were inserted at the location of
+the **Component Children** node.

+To fully understand this concept it's important to understand node hierarchies.
+Visual nodes can be placed in a hierarchy which will cause them to be layouted and drawn appropriately.
