Hello,Hi
Unless I misunderstood the point you're trying to state, I don't see any issue here.
I was looking at Arch Linux Arm's (ALARM) website and I realised, a lot of their support just points right back to the ArchWiki.
I thought the ArchWiki was only designed for the official distribution (Arch Linux) and not any other ports for other architectures?
While the Arch wiki is primarily designed to host information
about the official Arch Linux distribution, it is nonetheless a
source of information everyone is free to point to (just like any
other wiki).
Even people from completely different distributions (I mean, not
necessarily Arch-derivatives) often use and point to the
Arch wiki. As long as the info stored on it are relevant for your
case, I don't see any reason why you shouldn't use it.
