Slight clarification on mine docs
Slight clarification on mine docs

I found these docs while trying to get mine data into pillar... there's
this great about the mine runner that's very helpful. Taking the
suggestion was exactly what I needed and it works, but after having
the example in my codebase I forgot that it would only work in a Pillar
SLS file, not a state. In retrospect, that was pretty silly... but I'm
adding some wording here to make that even more clear.
