 The program can handle various modeling scenarios including viscoacoustic, isotropic viscoelastic, anisotropic viscoelastic (VTI, ORT, and TTI), solid and water free surfaces, and water-solid interfaces.
 
 # Installment
-The program is written in FORTRAN 90 and includes various modules such as MainOMP.f90, C_DF.f90, Gauss_Quad.f90, Grid_Model.f90, interp.f90, MATRIX_YYXZ.f90, MS_DF.f90, Viscoelastic.f90, and Viscoelastic2.f90. 
+SCSM2.5d OpenMP version: Compile MainOMP.f90, C_DF.f90, Gauss_Quad.f90, Grid_Model.f90, interp.f90, MATRIX_YYXZ.f90, MS_DF.f90, Viscoelastic.f90, and Viscoelastic2.f90. 
+
+SCSM2.5d MPI/OpenMP version: Compile MainMPIOMP.f90, C_DF.f90, Gauss_Quad.f90, Grid_Model.f90, interp.f90, MATRIX_YYXZ.f90, MS_DF.f90, Viscoelastic.f90, and Viscoelastic2.f90.
 By substituting MainOMP.f90 with MainMPIOMP.f90, the program can be converted to an MPI/OpenMP version that supports fully-parallel computation, utilizing cores equal to the number of wavenumber samples. 
 This enhancement reduces computation time to less than 1.5 times that of 2D modeling. 
+
+Windows: If you don't have Fortran compiler, you try the 'target.exe' with different input files (2.5Dseis_SCSM.inp and relaxation_time.inp) in Example folder.
+
+Linux: run 'run.sh'.
+
+HPC: run 'runOMP.sh' or 'runMPIOMP.sh'.
