Thanks so much for this contribution!  I have a feeling that a lot of people are going to need these records soon!

+HTTPS adds an HTTPS record to a domain. The name should be the relative label for the record. Use `@` for the domain apex. The HTTPS record is a special form of the SVCB resource record.
+
+The priority must be a positive number, the address should be an ip address, either a string, or a numeric value obtained via [IP](../top-level-functions/IP.md).
+
+The params may be configured to specify the `alpn`, `ipv4hint`, `ipv6hint`, `ech` or `port` setting. Several params may be joined by a space. Not existing params may be specified as an empty string `""`
+
+Modifiers can be any number of [record modifiers](https://docs.dnscontrol.org/language-reference/record-modifiers) or JSON objects, which will be merged into the record's metadata.
