LGTM - for anyone unfamiliar, AUR is the Arch User Repository for unofficial packages, while pacman is the official package manager.

@rwrr It seems like the deno package on pacman is on version 1.4.2 and deno-bin on AUR is version 1.4.6. So it would be great if both of these versions are visible in the README.

I don't think that's a good idea because then the README will have to be repeatedtly updated to show the latest version.

@MarkTiedemann That is not true, it just needs to explain both yay -S deno-bin (as before this PR) and pacman -S deno (instead of yay -S deno). The deno docs don't need to mention version numbers at all, it's just that the AUR package deno-bin will tend to be more up to date than the official package deno, and users may prefer either one.

Oh, I misunderstood. I read @rwrr's comment as saying that both deno versions, pacman 1.4.2 and AUR 1.4.6, should be included in the README. Thanks for clearing this up, @solson!

Yes, I'm fine with both pacman deno and AUR deno-bin being included (as long as no specific version numbers are mentioned).

The month passed, and there is still only an AUR solution in the README.

As an archlinux user I can approve the proposed changes. The official repositories are deemed trustworthy and thus should be the ones recommended here. The Arch User Repository package deno-bin has been removed in favor of the new official package deno, because it provides no real benefit in comparison. The only relevant AUR package at this point is deno-git, which downloads and builds directly from the git repo on the user's computer. If you want to mention this package (which is not mandatory imo), a note about it being user-provided content should be included.

Should the AUR installation method be added back? The forked repository under my personal account has been deleted. If I modify the content, should I reopen a pull request?

Sorry for the delay in review. This looks good to me. Thank you for the inputs & advise.
