 Public buckets can be set up in either one of two ways:
 
 - Expose your bucket as a custom domain under your control.
-- Expose your bucket as a Cloudflare-managed subdomain under `https://r2.dev`.
+- Expose your bucket using a Cloudflare-managed `https://r2.dev` subdomain for non-production use cases.
 
-To configure WAF custom rules, caching, access controls, or bot management for your bucket, you must do so through a custom domain.

 ### Minimum TLS Version
 
 To specify the minimum TLS version of a custom hostname of an R2 bucket, you can issue an API call to edit [R2 custom domain settings](/api/resources/r2/subresources/buckets/subresources/domains/subresources/custom/methods/update/).
 
+## Add your domain to Cloudflare
+
+The domain being used must have been added as a [zone](/fundamentals/setup/accounts-and-zones/#zones) in the same account as the R2 bucket.

+- If your domain is already managed by Cloudflare, you can proceed to [Connect a bucket to a custom domain](/r2/buckets/public-buckets/#connect-a-bucket-to-a-custom-domain).
+- If your domain is not managed by Cloudflare, you need to set it up using a [partial (CNAME) setup](/dns/zone-setups/partial-setup/) to add it to your account.
+
+Once the domain exists in your Cloudflare account (regardless of setup type), you can link it to your bucket.
