+This version we modified the code to deal with the case that param_card.dat is generated by SPheno. Sometimes it can't be directly used in MG5 and it needs "update missing" to update the parameter file and make MG5 work smoothly. 
+
+Installation Guide 
+Environment Setup:
+  1. Python2.7.X(X>3)
+  2. Delphes 3.4.2(Delphes3.5.0 will not work). When installing Delphes 3.4.2, need to modify Delphes/validation/DelphesValidation.cpp, add "#include TF1.h" and then make
+  3. Pythia 8245(Pythia 8.3 will not work)
+  
+Steps: 
+  1. git clone [website]
+  2. autoreconf  ----> If can't autoreconf, $export ACLOCAL_PATH="/usr/share/aclocal/:/usr/local/share/aclocal"
+  3. ./configure
+  4. make -j4
