+The reconstruction of particle tracks and clusters in an High Energy Physics detector
+requires information about the geometrical and material properties of the various
+tracking and calorimeter subdetectors.
+In general, a higher level view on the detector geometry is needed than for the purpose
+of simulating the detailed detector response with tools such as Geant4\cite{bib:geant4}.
+This higher level view typically involves the abstraction of detector layers, the corresponding
+measurment surfaces, accumulation of dead material along a path and conversion between cellIDs and
+positions.
+While in principle it is of course possible to extract this information from the detailed
+detector geometry model used for simulation, doing so would tightly couple the reconstruction
+code to the specific implementation of the simulation model.
+\DDR provides a generalized API for reconstruction that can be used to decouple the details of
+the \DDH\cite{bib:DD4hep} detector geometry model from the reconstruction algorithms.

+\section{Introduction}
+\label{sec:ddrec-manual-introduction}
+%=============================================================================
+\noindent
+This manual introduces the \DDR package which is part of \DDH and provides the
+high level view on the HEP detector geometry that is needed during reconstruction and
+analysis.
+In the detailed simulation of the response of a typical High Energy Physics detector
+very little information is needed in principle on the actual structure of the material
+distribution in the detector. This becomes obvious if one considers the fact that
+the Geant4 program is also used in medical applications where the human body
+is approximated by a voxelised phantom.
+During the reconstruction of particle trajectories and calorimeter clusters, in particular
+in the phase of pattern recognition, one typically regards the detector in an abstract
+structure of measurement surfaces or volumes that generally follow a layering structure.
+\DDR provides an API that provides this information for reconstruction algorithms, thereby
+decoupling the details of the actual simulation model used from the reconstruction code.
+\noindent
+The \DDR API provides the following functionality:
+
+\begin{itemize}\itemcompact
+\item description of measurement surfaces with coordinate systems for
+ track finding and fitting
+\item description of non-active surfaces with material properties in
+ order to take efffects of multiple scattering and energy loss
+ into account
+\item conversion of cellIDs assigned to simulated tracker and calorimeter hits
+ to positions of readout cells and vice versa
+\item access to a list of materials between any two points inside the world
+ volume of the detector
+\item average material properties between two points
+\item computation of radiation and interaction lenghts for detector layers, modules
+ or arbitrary sections through the detector
+\item ...
+\end{itemize}
+
+\noindent
+In this manual we describe the different classes in \DDR and how they can be used
+in the construction of the detector geometry and at reconstruction.
