+   @section xAODBaseOverview Overview
+
+   This is the most base-package of the xAOD EDM. It defines general
+   interfaces that are used in all parts of the xAOD code.
+
+   @section xAODBaseClasses Main Types
+
+   The main enumerations, definitions and classes of the package are
+   the following:
+      - xAOD::Type::ObjectType: Enumeration describing all major xAOD
+        object types.
+      - xAOD::IParticle: Interface for all particle-like EDM classes
+      - xAOD::IParticleContainer: Base class for all the particle-like
+        containers in the xAOD EDM.
