@Dhananjhay Are you still working on this? We have discussed this in the past, I was hesitant to introduce too many things into the basic template, especially since test workflows are going to vary so much (e.g. should we still use black and isort??).

Hey @pvandyken! I started working on this a few weeks ago but it's been a minute since I looked at this feature/PR. It seems to be pretty outdated (we want to move towards using pixi and this PR still works with miniconda...). I think the idea was introduce users to boilerplate CI pipelines but I agree on the concept of keeping things simple. Happy to discuss this further with you and @akhanf.
