How to install tig docs via Homebrew?

I installed tig via Homebrew and tig works okay, but is there are way to also cleanly install its man pages via brew too instead of from source (i.e. avoiding make install-doc as described at https://github.com/jonas/tig/blob/master/INSTALL.adoc)

Solution

If you installed Homebrew with standard install directories, i.e. relatives to /opt/homebrew, there are 2 commands to register the binaries and man files to be used:
/usr/bin/sudo -s
echo /opt/homebrew/bin >/etc/paths.d/homebrew
echo /opt/homebrew/share/man >/etc/manpaths.d/homebrew
exit
If you are using bash or zsh as your actual shell, you will have to enter one simple command to take into account these 2 environment modifications:
. /etc/profile
If you want to learn more how these 2 directories are used under MacOS X, read:
man path_helper
