+      - You can use the handlebars as usual in your response, though some of handlebars were built specifically for http based protocols and might not work as expected. For example, you can not use `code` helper for gRPC. To extract some value from the gRPC request body, you can still use `capture` helper like you would extract information from http request body, but you don't need to specify `from='body'` key/value. You can always load your own handlebars to Camouflage (Check External Helpers section).

+| `enums` | `String` | The type to use to represent `enum` values. Defaults to the numeric value.
+| `bytes` | `Array` or `String` | The type to use to represent `bytes` values. Defaults to `Buffer`.
+| `defaults` | `true` or `false` | Set default values on output objects. Defaults to `false`.
+| `arrays` | `true` or `false` | Set empty arrays for missing array values even if `defaults` is `false` Defaults to `false`.
