I made a little progress. I edited the index.wml file in
webwml/english/ports/powerpc and made the corresponding html file. It
looks good, it reads like this:
...
Debian on 32-bit PowerPC (powerpc)
It first became an official "release architecture" with Debian GNU/Linux
2.2 ("potato") and had retained that status until the publication of
Debian 9 ("stretch"). The last supported release for 32-bit PowerPC is
Debian 8 ("jessie"). See the release note and installation manual for
further information. Since the powerpc architecture is no longer
officially supported, the repository of powerpc can be found at the
Debian ports website. The latest installer images can be found at
cdimage ports.
Debian on 64-bit PowerPC (ppc64)
In 2012 the ppc64 architecture was added to the Debian ports site. More
information about this port can be found at the ppc64 wiki. The latest
installer images can be found at cdimage ports.
Debian on 64-bit Little Endian PowerPC (ppc64el).
Where can I transfer the edited index.wml file for you guys to read and
comment?
