 Serialization works in two stages: packing and serialization proper. Packing stage converts concrete objects to generic maps and lists that can then be serialized to a format of choice.

 To start serialization you need a fresh instance of `PackingSession` and call `pack` on and an appropriate packer class (generated for `@SerializableClass` annotated class). This will populate the packing session and return the reference of the "root" object. Then you can use those data to create output in the format of choice. This does move require from library user to write that final piece of logic, but that is not as complex as it sounds. Here is an example of `serializationMapper` function for converting packed objects to JSON for Android:
 
 
-```
+```Kotlin
 fun serializationMapper(obj: Any, path: String = ""): Any = when(obj) {
     is Map<*, *> -> JSONArray().apply {
