 /// \class AliMUONSegmentation
 /// \brief Container class for modules segmentations
 ///
+/// It provides access to segmentations on all levels:
+/// - mapping segmentation
+/// - DE segmentation (operating in local DE reference frame)
+/// - module segmentation (operating in global reference frame)
+/// As some detection element are sharing the same objects
+/// (AliMpVSegmentation, AliMUONVGeometryDESegmentation),
+/// all segmentations objects have to be always deleted
+/// altogether via deleting this container object.
