 [NOTE]
 ====
-While RESTEasy supports auto-negotiation, when using Quarkus, it is very important to define the `@Produces` and `@Consumes` annotations.
-They are analyzed at build time and Quarkus restricts the number of JAX-RS providers included in the native executable to the minimum required by the application.
-It allows to reduce the size of the native executable.
+When JSON extension is installed such as `quarkus-resteasy-jsonb` Quarkus will use this by default for most return values, unless the media type is explicitly set via
+and `@Produces` or `@Consumes` annotation (there are some exceptions for well known types, such as `String` and `File`, which default to `text/plain` and `application/octet-stream`
+respectively).
+
+If you don't want JSON by default you can set `quarkus.resteasy-json.default-json=false` and the default will change back to `application/octet-stream`. If you set this
+you will need to add `@Produces(MediaType.APPLICATION_JSON)` and `@Consumes(MediaType.APPLICATION_JSON)` to your endpoints in order to use JSON.
