+|`apiVersion`| String | Determines which **major** version of the [Parser-API](https://github.com/asyncapi/parser-api) the template uses. For example, `v1` for `v1.x.x`. If not specified, the Generator assumes the template is not compatible with the [Parser-API](https://github.com/asyncapi/parser-api) so it will use the [Parser-JS v1 API](https://github.com/asyncapi/parser-js/tree/v1.18.1#api-documentation). If the template uses a version of the [Parser-API](https://github.com/asyncapi/parser-api) that is not supported by the Generator, the Generator will throw an error.
 |`supportedProtocols`| [String] | A list with all the protocols this template supports.
 |`parameters`| Object[String, Object] | An object with all the parameters that can be passed when generating the template. When using the command line, it's done by indicating `--param name=value` or `-p name=value`.
 |`parameters[param].description`| String | A user-friendly description about the parameter.
