Sorry it might be my turn on the Dunce hat but what is so "Git" here other than the contribution calendar popularized by Github then copied by Gitlab?
Like I get it, but English is fluid and is it really that far to make the assumptive leap from "git" to "github/lab/service", seems pretty clear what they meant (even if it's not completely/technically/um-actually correct because git != github).
(Okay there's also `git` in the URL, I noticed, which means whoever made the page had that mental mapping in mind but still...)
I just feel clickbaited that this item is at the top of this forum. I'll stop engaging with this now. Nothing of interest for me here.
