Update the explanations for DNS configuration
It should be nice to have something clear enough to point people to this page. A few screenshots on the OVH website should help as I advice to use their service.
Additionally, we must change the explanations: CNAME record for root is simply not acceptable. Alternatives are A + AAAA record or HTTP redirection, each with annoying counterparts. OVH does not support ALIAS/ANAME virtual fields, but it may hopefully change one day?
