Add and configure CentOS ond Red Hat Satellite

Hi

I am new to Red Hat Satellite, I have a configured CentOS 7 repos
and i have been trying to add it to the Satellite it registers it but when it comes to adding the katello agent step it says there is no repos.

I have tried following the steps on how to register a host, went through a couple discussions. I am at loss now any help would be appreciated.

Running Satellite 6.6

• If there is also any videos or proper guides on how to configure satellite after the initial install or Satellite for dummies would appreciate if i could be pointed in the corrected location.

We are planning on moving our host from foreman version 1.xx over to Satellite. so any help is more than welcomed.

Thank you
