Documentation of Nexus RPM configuration with clients

We have an OSS Nexus RPM where we trying to host apt/yum packages for our clients servers (CentOS, Redhat, Ubuntu, Debian). I need someone who can bring up a strategy that can be used to find and upload packages, setup few client then test them to make sure they are all getting their packages only from Nexus.into Nexus rpm. One of the big challenges is to take find a to handle dependencies. Once the setup is tested and it is working, I need the full documentation of the the setup delivered.
