Dear User,

If you read this text, the NMSSM31.tgz file was unpacked  successfully. 

a) Call  [g]make   for compilation.   Makefile needs gmake 
options. If gmake is absent, try make. 

b) In CalcHEP session choose 
   "IMPORT OF MODELS" 
menu line in the top level menu. CalcHEP asks you about destination
of model file. It should be   
  Dir= ... /NMSSM31/models
