Ah you’re suggesting I just use theirs which is:
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [https://www.contributor-covenant.org/it/version/1/4/code-of-conduct/][version]
I guess I don’t know how much you added/changed from their original. So, since you edited/added to their CoC, and I’m wanting to edit/add to yours - I thought perhaps I’d need to attribute you, not Contributor Covenant?
