@sierra-moxon I just added a curation guide for providers in https://github.com/biopragmatics/bioregistry/blob/create-pull-request/patch-0178d13/docs/guides/providers.md. Can you take a look at this and tell me if it's sufficient to explain what's going on here?

@rombaum since you also recently curated some providers, your feedback would be helpful too. The goal is to get enough information in this page that someone new can read it and understand what to put where, and why

Makes sense, thanks!
