How to register client to smart proxy?

Hi , sorry if this has been asked before but I couldn’t find the answer . I’ve installed katello server and smart proxy based on Foreman :: Plugin Manuals , but how can I register a client to using the smart proxy ? is there a document for this ?

for a client connect to katello server I used this.
yum -y install http: `//katserver.domain.com/pub/ katello-ca-consumer-latest.noarch.rpm

subscription-manager register --org= "org_name" --activationkey= "key1"

You perform effectively the same steps, except that you would use the hostname of the smart proxy:

yum -y install http://mysmartproxy.domain.com/pub/ katello-ca-consumer-latest.noarch.rpm
subscription-manager register --org= "org_name" --activationkey= "key1"
