+===== Creating LCIO files =====
+In many cases, HepSim detector simulations were done using ILCSOFT-derived software, such as those used for ILC, CLIC, etc. experiments.
+To perform Geant4 simulations, you will need to convert PROMC to SLCIO or STDHEP files. You can convert ProMC files with truth-level information to STDHEP or LCIO (MCParticle) with full simulations using promc2stdhep or promc2lcio converters:
+<code bash>
+wget http://atlaswww.hep.anl.gov/hepsim/soft/promc_convert.tgz
+tar -zvxf promc_convert.tgz
+cd promc_convert
+./promc2lcio.sh input.promc output.slcio    # convert to SLCIO
+./promc2stdhep.sh input.promc output.stdhep # convert to STDHEP
+</code>
+You can convert all files in a directory with ProMC files as:
+<code bash>
+./batchconverter stdhep [DIR with ProMC files] # convert to STDHEP files
+./batchconverter slcio  [DIR with ProMC files] # convert to LCIO files
+</code>
+Files in the LCIO or STDHEP formats can be used as input for DD4HEP or SLIC simulation packages.
+Many samples of HepSim were created with a dedicated FPadSim package. See [[hepsim:dev_fpadsim|FPadSim section]].
