+# Self Entity Reference field
+
+Defines an entity reference to self via a computed field. 
+This allows rendering a node as an entity reference field with a different
+display mode.
+
+1. Displaying a "Hero" or header view mode within the full content view mode.
+1. Rendering a different view mode within the search_index view mode. This can
+   be helpful if using layout builder on the full content view mode but want to
+   index additional fields.
