-This example creates a regional mesh using transversely isotropic PREM
+This example creates a regional mesh using the 3D Berkeley model SEMUCB_A3d
 and runs a spectral-element simulation.
 
+In the Par_file, we also add the following parameters to use a specific Berkeley source time function:

 The simulation is setup to use 4 CPUs only, thus can be run locally on a desktop machine
 (needs to have MPI installed).
