Sample template file for provisioning

Hi I am doing a poc for IS installation through command central. I have done below :-

  1. installed cc and spm through bootstrapper.
  2. Added image repository in cc following the naming convention.
  3. Added IS license key follwoing naming convention.
  4. I am ready to install product now, I have checked data/template directory and in is-layer directory I can see two files template.yaml and

Can anyone tell me which file I should edit for IS installation, can anyone provide me a sample template file which is used for successful installation.
