Since I am fairly new to rust, I have a hard time understanding how to use this library.
It would be great if that could be expanded

I would like to underline this message due to I tried to use it but it is taking me ages to understand what to touch.
Nevertheless great work mate!!

I do plan on making new releases, so I'll make sure to update the docs when I do.
