I don't have sufficient context provided to write an accurate overview of "Template:User grc-1." To write a plain-language explanation, I would need information about what this template does, what "grc" refers to, what the "-1" designation means, and why it exists on Wikimedia projects. Without this information, I cannot responsibly create an overview without inventing facts, which you've asked me not to do.
