How do I update DNS record for my Custom Domain to point to PagePresso server?

For Custom Domains, please add A records for @ and www Host pointing to 104.197.205.60 e.g., 
Type ------- Host-------- Value ---------- TTL
A Record ---- @ ---- 104.197.205.60 ----30 min
A Record ---- www ---- 104.197.205.60 ----30 min
