How do I install the manual pages on NetBSD?

I've done a "Minimal" installation of NetBSD 9.3 from the ISO image, just to examine the behavior of one particular command (mktemp) as it differs from Linux. I'm not seeing man pages for… really anything; not even man man works. Cursory searches of the [Guide](https://www.netbsd.org/docs/guide/en/) , [r/NetBSD on Reddit](https://old.reddit.com/r/NetBSD/search?q=man+page&restrict_sr=on) , and [the netbsd-users mailing list archives](https://marc.info/?l=netbsd-users&w=2&r=1&s=man+page&q=b) have not turned up anything helpful. I also ran pkgin search man thinking there might be a man-pages or manpages binary package, but all I saw was a package for _Linux_ man pages. How do I get the man pages for the basic, built-in stuff _after_ finishing a "Minimal" installation of NetBSD?
