-## Response Templating
 Response headers and bodies can optionally be rendered using [Handlebars.Net](https://github.com/rexm/Handlebars.Net) templates.
 This enables attributes of the request to be used in generating the response e.g. to pass the value of a request ID header as a response header or render an identifier from part of the URL in the response body. To use this functionality, add `.WithTransformer()` to the response builder.

 By default, only the response (headers, statuscode, body) are transformed when the  `.WithTransformer()` or `UseTransformer` are defined.
 In case you also want to transform the contents from a referenced file (via `BodyAsFile`), an additional parameter need to added. Like `.WithTransformer(bool)` or `UseTransformerForBodyAsFile = true`.
