 Welcome to chroma's documentation!
 ==================================
 
+Chroma is a high performance optical photon simulation for particle physics detectors.  It tracks individual photons passing through a triangle-mesh detector geometry, simulating standard physics processes like diffuse and specular reflections, refraction, Rayleigh scattering and absorption.  
+
+With the assistance of a CUDA-enabled GPU, Chroma can propagate 2.5 million photons per second in a detector with 29,000 photomultiplier tubes.  This is 200x faster than the same simulation with GEANT4.
