ACR vs ACR

Just came across this:
https://github.com/alexeilebedev/openacr/blob/master/txt/acr.md

Might want to help clarify that this project has nothing to do with Auto Cross References. Whatever that is.

Start by reviewing the linked Auto Cross References page and the project's public description to distinguish the two uses of ACR. Update the project's public-facing documentation or description to state that OpenACR is an Accessibility Conformance Report project and is unrelated to Auto Cross References; done means the distinction is clear to readers.
