+=== Execute geant4 simulation ===
+<code>
+geant4$ primag4sim primag4sim.conf
+</code>
+=== Rootmacros ===
+In order to execute rootmacros, the include paths need to be set.\\
+This can be done automatically with a ''rootlogon.C'' file.\\
+Create the rootlogon.C file:
+<code>
+$ cd ~/
+$ mkdir .rootlogon
+$ geany .rootlogon/rootlogon.C
+</code>
+Enter the following lines to your rootlogon.C file:
+<code>
+// This is the file rootlogon.C
+{
+  printf("\n Beginning new ROOT session\n");
+  gROOT->ProcessLine(".include your_path/primasoft/geant4");
+  gSystem->Load("<geant4_workdir>/tmp/Linux-g++/primag4sim/libprimadict.so");
+}
+</code>
+Here, ''your_path'' is the path to the primasoft git repository and the ''<geant4_workdir>'' can be found out by ''$ echo $G4WORKDIR''.\\
+Now root needs to know where to find the rootlogon.C file. Therefore in ''$FAIRSOFT_BUILD_DIR'/share/root/etc/system.rootrc' change the line:
+<code>
+Rint.Logon:    rootlogon.C
+</code>
+to:
+<code>
+Rint.Logon:    ~/.rootlogon/rootlogon.C
+</code>
+Now you can execute the rootmacro:
+<code>
+/geant4$ root -l rootmacros/test.C+
+</code>
