Hi @tgauth, I saw #907 got merged and thought of creating some reference documentation. Do you mind for a review :)?

Missing description for this resource property - presumably it's the full configuration as an object?

[michaeltlombardi]

The resource is only usable with export, but requires the map property to be defined, so do users need to export it with an empty object? Does the resource use the object for filtering during an export operation?

@tgauth mind filling in the gap here? I couldn't quickly find it from the resource.

Yes, exactly!

Users do not need to export with an empty object. Schema is still a work in progress :) have an open PR that will shift to not requiring the map and simply permit additional properties

Thanks, Tess. I'll wait for that PR to get merged and update this one.
