Adding in RPM support for Hugo

I see that there are deb packages but no RPM packages for Hugo. I wrote a RPM spec for the latest Hugo release and built x86_64 packages for CentOS 6, CentOS 7, Fedora 21, Fedora 22, Fedora 22 and Fedora 23 on my Copr account.

What would be the preferred method for adding the spec to the project and RPMs to the releases? Should I just fork the repo and create a packages directory with the spec file and a README (or a wiki page) with the steps on building your own RPM?
