Hi Will-

Apologies for the continued confusion. I believe Adam misspoke above. The config directory (with module.xml) goes at the top level of your module, next to the resources directory.

I was able to reproduce the problem you're seeing with the Fermentation.module file you provided, but moving the config folder to the correct location made it work.

I've made note for us to improve the documentation around this.

Let us know if have any further questions.
