@dfsnow It seems to me that most of these docs should probably live in the data catalog (ccao-data/data-architecture#10). If you're aligned, I'll deprioritize this issue and focus on the catalog for now, and then revisit this once we have a better sense of which documentation doesn't make sense to keep in the catalog.

@jeancochrane Works for me!
