Thank you for the work you did on this. i figured i had something to contribute to this project. it looks promising, but inactive since 2018... So, i decided to put in some Docker tests scripts to build and deploy docker containers with your code. i have also added my setup_env.py script which can help some people who might have a hard time. honestly it's not hard, but it helps me, i just drop it in, run it, and venv is ready to go. Let me know if there is anything else we can collaborate on. Pleasure. Manny E. 3w
