helpful documentation on S2P

[SathishVaithiyanadhan]

Hi,
I just started working on Automatic DEM generation. I initiated the process with software and now I am working on using various automatic pipelines to generate DEM.
I installed S2P yesterday and was quite unclear about using the pipeline. I couldn't find helpful documentation for me to access the pipeline.
I tried generating the new json file for my data with the respective specs and loaded the same in the terminal. But, it didn't work.
Is there any better way to access the pipeline for generating the DEM?
As it was mentioned it can be also used as a Python library, but I couldn't load it in Python. IDK why.
can you please help me in this regard, to generate the DEM and validate the DEM. I am trying to test both the Stereo and tri-stereo datasets.
In case further details are required, please let me know.
Looking forward to read back from you.
Thank you.
