AFAIK unless somethings changed you arent able to use Namesevers as they are used for the main domain, you will have to use a A domain or a CNAME to cover the domain. Sorry to break the news to you.
You answered your own question. They said to set CNAME or A record. As for the Nameservers, unless GitHub says otherwise, you are going to ask what the A Record or CNAME should be set on your domain name. Then, if you don't know how, ask your Domain Register about setting the CAME or A Record to what it needs to be for your domain name.
