-
-### CEPCSW Simulation Framework
-
-![](https://jupyter.ihep.ac.cn/uploads/upload_4d21e10bb49b9ec33c22f00c720dbfad.png)
-
-* The simulation chain is driven by Gaudi.
-* Detector description is from DD4hep.
-* Event Data Model is in EDM4hep format.
-* Detector response is done by Geant4.
-
-----
-
-#### Code is on GitHub
-* Detector description: [See Detector](https://github.com/cepc/CEPCSW/tree/master/Detector)
-* Event generator interface: [See Generator](https://github.com/cepc/CEPCSW/tree/master/Generator)
-* Detector simulation: [See Simulation](https://github.com/cepc/CEPCSW/tree/master/Simulation)
-  * [DetSimInterface: Gaudi Tool interface](https://github.com/cepc/CEPCSW/tree/master/Simulation/DetSimInterface)
-  * [DetSimCore: integrate Gaudi and Geant4](https://github.com/cepc/CEPCSW/tree/master/Simulation/DetSimCore)
-  * [DetSimGeom: integrate with DD4hep](https://github.com/cepc/CEPCSW/tree/master/Simulation/DetSimGeom)
-  * [DetSimAna: collect data from Geant4](https://github.com/cepc/CEPCSW/tree/master/Simulation/DetSimAna)
-  * [DetSimSD: detector response](https://github.com/cepc/CEPCSW/tree/master/Simulation/DetSimSD)
-* Job options: [See Examples/options](https://github.com/cepc/CEPCSW/tree/master/Examples/options)
-
----
-
-### Run simulation in CEPCSW
-
-* The simulation is run by following command:
-```bash
-$ ./run.sh Examples/options/tut_detsim.py
-```
-* The job option: `Examples/options/tut_detsim.py`. &lt;!-- .element: style=&#34;color:yellow; &#34; --&gt;
-* :writing_hand: copy the job option into your current directory. Edit your job option in the later exercises. 
-```bash
-$ cp Examples/options/tut_detsim.py my_detsim.py
-```
-
----
-
-### What&#39;s inside the job option?
-* Random Number Service
-  * Use `Seeds` option to control the random number sequences.
-* Event Data Service and PODIO writer
-* Geometry Service
-  * Different detector options could be loaded here via `compact` option.
-* Physics generator algorithm
-* Detector simulation algorithm
-
-
----
-
-#### Save detector response into ROOT file
-```python
-from Configurables import PodioOutput
-out = PodioOutput(&#34;outputalg&#34;)
-out.filename = &#34;test-detsim10-seed42.root&#34;
-out.outputCommands = [&#34;keep *&#34;]
-```
-* The EDM4hep format is used in the detector response.
-* All the collections created in simulation will be saved.
-* :writing_hand: modify the output file name.
-
----
-
-#### Control how many events to be simulated
-```python
-from Configurables import ApplicationMgr
-ApplicationMgr( TopAlg = [genalg, detsimalg, out],
-                EvtSel = &#39;NONE&#39;,
-                EvtMax = 10,
-                ExtSvc = [rndmengine, dsvc, geosvc],
-)
-```
-* :writing_hand: modify the `EvtMax` property and check the entries in the output.
-
-
----
-
-#### Random Number 
-```python
-from Configurables import RndmGenSvc, HepRndm__Engine_CLHEP__RanluxEngine_
-
-# rndmengine = HepRndm__Engine_CLHEP__RanluxEngine_() # The default engine in Gaudi
-rndmengine = HepRndm__Engine_CLHEP__HepJamesRandom_() # The default engine in Geant4
-rndmengine.SetSingleton = True
-rndmengine.Seeds = [42]
-
-```
-
-* Seed is used to initialize the state of the random number engine.
-* If two job set the same seed, the outputs will be same.
-* :writing_hand: modify the seed and see the difference.
-
----
-
-#### Geometry / Detector Description
-```python
-geometry_option = &#34;CepC_v4-onlyVXD.xml&#34;
-
-geometry_path = os.path.join(os.getenv(&#34;DETCEPCV4ROOT&#34;), 
-                             &#34;compact&#34;, geometry_option)
-
-from Configurables import GeomSvc
-geosvc = GeomSvc(&#34;GeomSvc&#34;)
-geosvc.compact = geometry_path
-```
-* The compact file is in XML format, which describes the detector. 
-* :writing_hand: change the geometry path and run simulation again.
-```
-geometry_path = &#34;Detector/DetEcalMatrix/compact/det.xml&#34;
-```
-
----
-
-#### Customize primary particles
-##### Particle Gun
-```python
-gun = GtGunTool(&#34;GtGunTool&#34;)
-gun.Particles =  [&#34;pi+&#34;, &#34;pi-&#34;]
-gun.EnergyMins = [100.,  100]  # GeV
-gun.EnergyMaxs = [100.,  100]  # GeV
-
-gun.ThetaMins =  [0,     0]    # deg
-gun.ThetaMaxs =  [180.,  180]  # deg
-
-gun.PhiMins =    [0.,    0.]   # deg
-gun.PhiMaxs =    [360.,  360.] # deg
-```
-
-* Particle name can be found in [`$ROOTSYS/etc/pdg_table.txt`](https://github.com/root-project/root/blob/master/etc/pdg_table.txt)
-* :writing_hand: change the particles, energies and directions.
-
-----
-
-##### Event Generators
-```python
-stdheprdr = StdHepRdr(&#34;StdHepRdr&#34;)
-stdheprdr.Input = &#34;/cefs/data/stdhep/CEPC250/2fermions/E250.Pbhabha.e0.p0.whizard195/bhabha.e0.p0.00001.stdhep&#34;
-
-genalg = GenAlgo(&#34;GenAlgo&#34;)
-genalg.GenTools = [&#34;StdHepRdr&#34;]
-
-```
-* There are several readers to read the output of event generators in different formats
-  * StdHep: `StdHepRdr`, lcio: `SLCIORdr`, HepMC: `HepMCRdr`.
-* :writing_hand: use the different readers to load different samples.
-* [The existing samples could be found here.](http://cepcsoft.ihep.ac.cn/guides/Generation/docs/ExistingSamples/)
-
----
-
-#### Customize Geant4 using [built-in commands](http://geant4-userdoc.web.cern.ch/geant4-userdoc/UsersGuides/ForApplicationDeveloper/html/Control/AllResources/Control/UIcommands/_.html)
-##### :writing_hand: Turn on the verbose during tracking 
-```python
-detsimalg.RunCmds = [
-    &#34;/tracking/verbose 1&#34;,
-]
-# Or
-detsimalg.RunMacs = [
-    &#34;run.mac&#34;,
-]
-```
-```bash
-# Below is the content of run.mac
-/tracking/verbose 1
-```
-
-* Each step will be print out. Remeber to redirect the output to a file.
-```bash
-$ ./run.sh my_detsim.py &gt;&amp; mylog
-```
-
