how to configure custom domain correctly?

i am kind of new to the plasmic, version’s done. now i wanna try saving the website with my custom domain but i wanna try do something but it always gives me errors like: “Invalid conguration”, “Set the following records on your DNS provider to continue: Type - CNAME; Name - www; Value - cname.plasmicdev.com”. what did i do wrong? what should i do?

Hi, where did you get your domain from what is your domain name server? You’ll need to update that to point the domain to the plasmic server by entering that information as the cname or a record.

well, i am kind of young and dont know what to do with cname or a record, the domain used is .com of course. which one can i use?? i just want to know what to fix and probably it will work
