Hi! From those docs, this metadata is

for packaging-related tools to consume

but newTrackon is not packaged as a python project, or is published to PyPI. The only supported ways to run newTrackon right now is via Docker, or by cloning the repo and installing dependencies manually.

Sorry I couldn't get back to you sooner.

I understand that it isn't published to PyPI or the sort, but it helps to manage a venv for local development.
