I have a free Cloudflare account and manage my DNS for my websites, but do I even need it anymore if I have your service? How would I set up your CDN and manage my DNS if that is the case? Do you have links to relevant articles and videos that can help with this? Additionally, Flying CDN doesn't require a Cloudflare account, as it leverages Cloudflare's Enterprise CDN in its service. Therefore, I believe I don't really need Cloudflare's service if I am utilizing yours and FlyingCDN.
