I'm trying to find the documentation on best practices for naming layers in Photoshop for export to Spine.

Specifically layer names in PSD that begin with [skin], [folder], [slot], [ignore], etc. This has been AMAZINGLY useful in my remedial tests, but I'd like to understand it more, but I can't find a link in the documentation. Probably because I don't know exactly what it's called and am just floundering.

Thanks in advance.
