 ### Kotlin Support

+Kotlin classes work with Moshi out of the box, with the exception of annotations. If you need to annotate your Kotlin classes with an `@Json` annotation or otherwise, you will need to use the `moshi-kotlin` artifact, and set up Moshi to use its converter factory. Add the KotlinJsonAdapterFactory last to allow other installed Kotlin type factories to be used, since factories are called in order.
 ```kotlin
 val moshi = Moshi.Builder()
+    // Add any other JsonAdapter factories.
     .add(KotlinJsonAdapterFactory())
     .build()
 ```
