+The above example will produce an `asyncapi.md` file where usage of the AsyncAPI document information (i.e. the `title`) is demonstrated.

 Every template must depend on the [`@asyncapi/generator-react-sdk` package](https://github.com/asyncapi/generator-react-sdk), which contains a template file's basic components.

 For example, if you want to generate an output using the above template, you need to have an AsyncAPI document with servers that use `mqtt` to generate your desired output. If your AsyncAPI document has server connections with `kafka`, the generation process will be terminated since the only supported protocol mentioned is `mqtt`.
