When starting fwbuilder after installing fwbuilder, fwbuilder-common,
fwbuilder-doc
(each of them is version 5.3.7-4.1), I am offered the option to watch
the Quick Start Guide by clicking on the "Watch the guide" in bottom
right corner of the pop up dialog.

This action gets the browser to open the link:
http://www.fwbuilder.org/4.0/quick_start_guide_1.html
However, as of today, the domain www.fwbuilder.org cannot be resolved.

1. fwbuilder.org is registered in the whois database.
2. The quick start guide does not seem to be available from
   fwbuilder-doc.
   At any case, in /usr/share/doc/fwbuilder-doc, there is no
   file whose name may hint at its being the quick start guide.
3. I looked for the file in Internet Archive:

https://web.archive.org/web/*/http://www.fwbuilder.org/4.0/quick_start_guide_1.html*
   and even there, I did not find the quick start guide.
