where to get user guide and developer guide?

[pylearn20]

The software is very impressive. A great effort! I would like to see many uses the software. I would like to use it. However, I could not find user guide or developer manual in the Range software web page or in github. I also could not register as a user in https://www.range-software.com/.

I found helpful guidance and tutorials in the help menu within the application (the question mark in the top right corner).
I just started tooking into the Range Software as well today. It looks great so far and I will try it out. Initially I also searched for a getting-stared documentation and struggled to find it.
