Could you please clarify what you mean by Check out? Does that mean download, unzip and put in those folder or something else. I am a little new so I am slightly confused to such jargon. Additionally, what do you mean by PYTHONPATH? For the record, I use Miniconda. I have created a VEnv thus far and have installed all those libraries (phew!). Finally, how would I make changes. Would I download the front end Python scripts and make the edits, then submit a pull request. I am pretty excited and can't wait to start some dev work!
