+        Geant4 extended examples - event generator
+        -------------------------------------------
+
+ Examples in this directory demonstrate various ways of primary event
+ generation.
+
+particleGun
+------------
+
+This example demonstrate 4 ways of the usage of G4ParticleGun shooting
+primary particles in different cases.
+
+exgps
+-----
+
+This example demonstrates the usage of G4GeneralParticleSource for generating 
+primary incident particle according to user defined distributions.
+
+userPrimaryGenerator
+--------------------
+
+This example shows how to create a primary event including several vertices and 
+several primary particles per vertex.
+
+HepMC
+------
+
+This directory contains examples for using HepMC as an interface with 
+various Monte Carlo event generators, such as PYTHIA.
+It also include an example for demonstrating MC truth handling with HepMC. 
+
+pythia
+------
+
+This directory contains the following examples:
+
+a) use of Pythia6 as Monte Carlo event generator, interfaced with Geant4, 
+and showing how to implement an external decayer based on Pythia6.
+The feature is activated by setting environment variable PYTHIA6 to point
+to the Pythia6 installation area.
+For details, please see pythia/decayer6/README.
+
+b) use of Pythia8 as an external decayer to replace native Geant4 decay
+tables for such resonances as tau+/- and B+/-, and to supplement Pythia8-based
+decay tables to those resonances where Geant4 native decay features are not
+implemented. 
+The feature is activated by setting environment variable PYTHIA8 to point
+to the Pythia8 installation area.
+For details, please see pythia/py8decayer/README.
