+## HTTPS records
+
+HTTPS Service (HTTPS) records allow you to provide a client with information about how it should connect to a server upfront, without the need of an initial plaintext HTTP connection.
+
+If your domain has [HTTP/2 or HTTP/3 enabled](/speed/optimization/protocol/) and [proxied DNS records](/dns/manage-dns-records/reference/proxied-dns-records/), Cloudflare automatically generates HTTPS records on the fly, to advertise to clients how they should connect to your server.
+
+:::caution
+Both HTTP/2 and HTTP/3 configurations also require that you have an SSL/TLS certificate served by Cloudflare. This means that disabling Universal SSL, for example, could impact this behavior.
