Only if it's been "properly installed"
The man pages for GNU are always hilariously passive aggressive on this point.
"If the documentation has been correctly installed at your site" is what I recall it saying. But I always imagined the real meaning to be something like
"If your sysadmin has drunk the entire bottle of GNU Kool-Aid, you can find an incredibly dense manual by typing ``info foo''. But if they are a normal person who just untarred and ran, well, dear peasant, you are stuck with this man page."
