 ## HTTP method
 
-Cloudflare's DNS-over-HTTPS (DOH) endpoint supports `POST` and `GET` for UDP wireformat, and `GET` for JSON format.
+Cloudflare's DNS-over-HTTPS (DOH) endpoint supports `POST` and `GET` for DNS wireformat, and `GET` for JSON format.
 
 When making requests using `POST`, the DNS query is included as the message body of the HTTP request, and the MIME type (`application/dns-message`) is sent in the `Content-Type` request header. Cloudflare will use the message body of the HTTP request as sent by the client, so the message body should not be encoded.
 
-When making requests using `GET`, the DNS query is encoded into the URL. An additional URL parameter of `ct` should indicate the MIME type (see below).
+When making requests using `GET`, the DNS query is encoded into the URL.
 
 ## Valid MIME types
 
-If you use JSON format, set `application/dns-json` URL parameter, and if you use DNS wireformat, use `application/dns-message` as either the URL parameter of `ct` or a `Content-Type` header for `POST` requests.
+If you use JSON format, set `application/dns-json`, and if you use DNS wireformat, use `application/dns-message`.
