Documentation and materials for new data practitioners

This is meant to be a compilation of various resources (onboarding guides, links to presentations, etc.) that would be useful for someone joining the Foundation as an analyst or data scientist and learning about the many datasets and systems we have. This page shouldn't be educating the new hire on those things but should be a springboard for learning about those things – in other words, the only content should be an index.
