+Viewfield
+======================
+
+Defines a field type to display a view.
+
+Nodes hold content. Views save queries. Wouldn't be great if a node could hold a
+saved query? Now it can.
+
+Viewfield is a field type module that allows to render a particular view within
+a field of an entity. When creating an entity, users can select the view to
+render from a list of views. When the entity is displayed, the view is run and
+the content is inserted into the field.
