I have searched both Squarespace and Cloudflare Support as well as blogs. I don't have any specific instructions on the best way to utilize the Free version of the Cloudflare CDN with Squarespace. If its even possible. I get a notification of SSL on the site.
Squarespace Support gave me this link:
Cloudflare Support DNS Setup instructions
If you can't do it on the Free plan, whats the best method on the Cloudflare premium plan? Change to the Cloudflare Name servers?
