+## Overview
+
+Detector benchmarks are meant to test for regressions in individual detector subsystems.
+The analysis is meant to avoid a complex reconstruction. 
+So for now this precludes using [juggler](https://eicweb.phy.anl.gov/EIC/juggler) for processing the events.
+[Physics benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/physics_benchmarks) will 
+include the full reconstruction chain processing.
