 To process truth-level events with FpadSim, you need a few things:
-  * Tag file with detector description
+  * Tag file with detector description. The concept of tag files is described in Sect.[[hepsim:dev_tags]]. You can find all submitted tag files in [[http://atlaswww.hep.anl.gov/hepsim/recotags.php|tag file catalog]]
-  * Singularity image with pre-built libraries to process the tag file
+  * Singularity image with pre-built libraries to process a given tag file
+The tag files should be processed with the simulation and reconstruction chain described above.
+This can be done by using [[http://singularity.lbl.gov/|Singularity]] that enables users to have full control of their environment. Install singularity (version 2.3.1 and above) and download the CentOS7 HEPSIM image with the
+FPadSim software.
+Here is the download link [[http://atlaswww.hep.anl.gov/hepsim/soft/centos7hepsim.img|centos7hepsim.img]] (>5 GB).
+The image includes basic CentOS7 environment, and programs such as SLIC, LCSIM, slicPandora, ProMC, Jas4PP and various
+converters.
+<code bash>
+wget http://atlaswww.hep.anl.gov/hepsim/soft/centos7hepsim.img # get the singularity image
+singularity  exec centos7hepsim.img  bash -l                   # setup fpadsim
+</code>
+After the last line, the environment should be ready. For example, type "slic -h". It shows the available commands.
+Now you can process the tag file:
+<code bash>
+wget http://atlaswww.hep.anl.gov/hepsim/soft/rfull102.tgz
+tar -zvxf rfull102.tgz
+cd ilcsoft/rfull102/
+./TEST.sh #  runs simple a test with single particles
+</code>
+The final file after pandoraPFA reconstruction with the name *hepsim.slcio" will be created in the same directory.
+Other files after simulation and track reconstruction steps will be located inside "output" directory.
+To process other promc files, download the required promc files and edit the file Test.sh
+More information can be found in Section [[hepsim:dev_singularity|HepSim singularity image]]
+===== Light version of FPadSim image=====
+David Blyth created a much lighter version of FPadSim image for EIC work described in Sec.[[fcs:eic:singularity|singularity image for EIC]]. It is based on Arch Linux, and does not contain the usual Linux environment included inside centos7hepsim image.
