I've purchased a domain, built the site documentation in Jekyll but now I need email accounts for that domain I have forwarding to the Github Pages repo. Per research I did not see this question asked. In the DNS of the company I am using do I just need to add the hosting account I have, such as Hostgator with the nameserver accounts for Github? In the end I would have four listed nameservers if I am understanding the setup correctly.
How should a domain setup be completed if the site is hosted with Github Pages but I need domain name email accounts, such as firstname.lastname@example.org?
