Hi!
I am writing a new thread so that it does not end up messy.
Yesterday and today I've been reading and adding @cindex to guix.texi  to make a new patch. I know that you don't mind that much about the number of contributions, but it was for myself mostly, to learn texinfo and to see how it applies to documentation.
I just added a few @cindex at the very beginning of the guix.texi file, to see if it is OK. But had some trouble with makeinfo, I was getting this kind of errors: https://paste.debian.net/1050349/.
Regards!
