Tillage Detection using SNAPPY

I’m quite new to SNAPPY. I am trying to detect changes on the farm over a short period of time and more specifically if the farm was ploughed or not. Is there any guideline to show the process step by step using SNAPPY in python?
I’ve found this guideline on mapping flood (Flood mapping using SNAPPY) and found it very helpful, but I’m looking for a similar guideline for detecting tillage.
Thank you for your help!
