 == MadEvent Interface
 
-In Order to use SysCalc from the MadEvent interface you need to 
+As all external module, SysCalc can be called either in the main flow or in a a-posteriori way via the command "syscalc" in the command interface (./bin/madevent or launch -i from the MG5 interface)
 
+In both case, the information from the run are used from the run_card and require to have use_syst on the run_card set on T.
+All the parameter correspond to those describe above.
+
+Concerning the PDF since the multiple line is not supported in the run_card, you can separate the various PDF line information by '&&'
