readthedocs is not working for me

[Promis-E]

Hi Everyone

I have been lookin at the readthedocs site , and working through the initial examples. I am using python 3.7 and hav found a few syntax errors (no problem , van work around that) , but I have found that as the examples progress , nothing is displayed on screen.
I appreciate the this is developed in python 2, but I have downloaded python 2.7 and get the same result. I have looked to report the issue on bitbucket , but cannot see anything on there for npcole/npyscreen.

I am no no expert , and want to do things for myself , but I cannot find a way to get into using this module . Any guidance on where to look for further support will be great.

Regards
