Fully free and open source?

Hi all.

Does anyone know how to build a complete RoPieee image from source? I see there is a GitHub org, but I wasn’t able to find any image build instructions in my quick skimming of the repos there. I like to keep my network pretty secure, and want to make sure I can trust any software I install. Also, if there is a repo it would allow me to determine if RoPieee is fully GPL compliant.

Any help is appreciated.

RoPieee is free, but not open source.
The kernel tree I use is available on github.
