I like the idea of explicitly explaining how to cite SUAVE. I think we should ask the full crew and figure out what we want as our preferred citation. We have the Zenodo link on the top right now that makes a bibtex to our DOI (it goes to SUAVE 2.0 right now), but maybe it's not clear to use that. I like that it sets an exact version of the code. But maybe should we prioritize publications?
