Hi Erika,
I see, the tags however... But when exporting, the bones don't exist yet? What I do is, after exporting the PSD to PNG, I'll edit the JSON export, then copy a template bone set I have from another JSON file to the one here. Then I go about moving the bones in place on top of the parts, renaming and amending as necessary. Then once I'm happy with the bones, I just drag and drop the [slots] onto the same named [bones].
