   *All the above parameters are optional.*
   You can use all the properties of the [swagger specification](https://swagger.io/specification/v2/) and [openapi specification](https://swagger.io/specification/), if you find anything missing, please open an issue or a pr!
 
-  *Please note that when you specify `openapi` option, it will take precedence and ignore the `swagger` option.
+  fastify-swagger will generate Swagger v2 by default. If you pass the `opeanapi` option it will generate OpenAPI instead.
 
   Example of the `fastify-swagger` usage in the `dynamic` mode, `swagger` option is available [here](examples/dynamic-swagger.js) and `openapi` option is avaiable [here](examples/dynamic-openapi.js).
