  • NB: it's better to use a tag version that specify more than ocaml-version

@haochenx I don't have correct accessibility to kxcdev/prr in order to push my commit to the repo.

invitation sent.

though this issue is about adding documents to this repository and the link to kxcdev/prr is simply a pointer of usage example that may help writing such documents. (also this issue is kinda low priority now)
fyi: @kxc-wraikny

@haochenx
I thought this issue is about changing the container image used by CI in kxcdev/prr toghcr.io/kxcteam/ocaml-general:ubuntu.22.04-ocaml.${{ matrix.ocaml-version }}-node.hydrogen-amd64, is that wrong?

[haochenx]

nope. I have changed the title to better reflect my intention (sorry that it wasn't clear before)
