Do we just need to install <a href="https://github.com/andreasplesch/conda">https://github.com/andreasplesch/conda</a>? Could you provide instructions on how to install into our own docker or jupyter enviroments? Looks like <a href="https://mybinder.org/">https://mybinder.org/</a> leads the way. Or do you want to support everyone’s development with your docker? …could get kind of crowded. I think the best solution is to create a conda package for x3dpysail which includes the python and the jar.
