CNAME record setup VestaCP

Zero Trust 1.1.1.1

Hi, I have a setup of WHMCS + VestaCP + Cloudflare Partner Program + RailGun. So basically I setup Cloudflare module for WHMCS and setup the Cloudflare using WHMCS for my domain. Then in my Cloudflare partner panel it shows the domain is online and in WHMCS I get:

" Working with Cloudflare over CNAMES

  • On your authoritative DNS, make sure that each activated record is pointing to its Cloudflare-specified CNAME.
    • For example: If www.example.com has been activated, then your authoritative DNS should set www.example.com as a CNAME to www.example.com.cdn.Cloudflare.net
  • All proxy targets should resolve on the internet.
    • This may require modifying your authoritative DNS for the proxy target.
    • For example, if the proxy target for subdomain.example.com is Cloudflare-resolve-to.example.com then Cloudflare-resolve-to.example.com should be created as an A or CNAME record and pointing to the desired server.

I need to know how should I point my CNAME records in my DNS manager so it would point to Cloudflare. Need Urgent Help Please!!!
