Indeed -- I find it kind of hard to believe that someone with truly zero programming experience knows what github or even knows what source control is.
I have no doubts about the main thrust, just some details seem as if they are embellished.
Github and source control are the very first things out of my mouth when someone expresses interest in programming. They were the first things that were recommended to me. I basically say to go get set up on github and walk through the tutorials, and 'follow' me while you're at it. Instant community feeling and the new programmer can always Stack Overflow 'how to revert my last commit'. It's low-hanging fruit to get set up.
Next, I usually suggest grabbing an introductory reference and a bunch of small projects (usually my go-to is Project Euler) in the language of their choice. What she's doing is exactly what I'd recommend if you were brand new and wanted to get a feel for the landscape.
