Point external domain name to website



I bought a server from online.net and i have a wordpress site hosted on it inside a specific a folder.

However, I want to add a second website now, so i created a second folder, however I have my domain name on Gandi and I would like to know what are the proper DNS settings that i should set ?

I have already created an “A” record pointing to the ip of my server, but I do not know what to put on the CNAME?

Thank you in advance for any help you can bring me
