+@mainpage The MeasurementBase class 
+
+@section introductionTrkMeasurementBase Introduction
+
+This package includes the pure absract base class Trk::MeasurementBase 
+for all fittable measurements in the Tracking realm. 
+It holds the minimal common interface which is characterized by
+
+   - Trk::LocalParameters*
+   - Trk::ErrorMatrix*
+   - Trk::Surface*
+   - Trk::GlobalPosition*
+
+The following child branches are (planned) to inherit from this one (only base classes are given here):
+
+   - Trk::RIO_OnTrack, calibrated measurement on track
+   - Trk::Segment, track segment class with calibrated measurements on track
+   - Trk::CompetingRIO_OnTrack, data structure for DAF with multiple competing RIO_OnTracks
+   - Trk::SpacePoint, 3D space points to allow fitting on HLT level (planned)
+   
+Please let me know of any errors, or if anything is unclear.
