Hey, thank you for chiming in! I'll try to improve documentation soon by recording short videos on its usage, hope that will help better.
No worries, I just figured it out and thought I share my experiences :D I think videos would be overkill. A short pdf or a section "usage" in the readme should do the trick :) And maybe clarify in the description that this is not an application with GUI. And also awesome job! This is exactly how I wanted to tackle the problem but never had the time to implement it XD
