Koji is a system to manage rpm builds via mock on a farm of builders.
It does a lot to manage this, but at the end of the day that is what it
is for.
 
case use from development, list actors, etc., administrator manual.

Koji may be a bit overkill if you're only adding a few packages.
Perhaps you're looking for the tools needed to actually take those
packages and turn them into an installable set?

No, we want use koji, for our own distribucion, we  have infrastructure so what we need is only information about implementation.

thanks

And contribute with fedora in translation,  maintenance with packages. No being spin of fedora.
