@JulioAPeraza, I'd love to get your thoughts on this one. I want to expand the maintenance documentation, and you're the one who will use that documentation the most.

Should we also add the guidelines for testing with local environments using pytest -v nimare and make html? The step will look like this:

conda create -p /path/to/nimare_env pip python=3.9
conda activate /path/to/nimare_env
pip install -e .[all]

Should we also add the guidelines for testing with local environments

I think that's a good idea. That's important for any devs, rather than just maintainers, so I'll add it to the overall development guide.

@JulioAPeraza is there anything else you'd like to see in this PR?

[JulioAPeraza]

No, I think this looks good.
