+Helper modules help you to interact with Kompendium.
+
+Some functionality is not possible or difficult to do with Kompendium by default. Modules in this folder help you to get
+functionality that would otherwise be difficult.
+
+The first one of which is [Protobuf java converter](protobuf_java_converter.md) which translates java protobuf classes 
+to `customTypes` entries.

+The `Protobuf java converter` functions allow you to generate documentation from your generated Java classes.
+Since Kompendium relies a lot on `KProperties` we have yet to find a way to connect this with our Java.
+For now the documentation is generated for the `customTypes` in `NotarizedApplication`.
+
+## Usage with Kotlinx
+
+setup:
+```kotlin
+ install(ContentNegotiation) {
+  json(Json {
+    encodeDefaults = false
+    // Combine the kompendium serializers with your custom java proto serializers 
+    serializersModule =
+      KompendiumSerializersModule.module + SerializersModule { serializersModule = yourCustomProtoSerializers }
+  })
+}
+```
+
+For one message and all its nested sub messages:
+```kotlin
+private fun Application.mainModule() {
+  // ...
+  install(NotarizedApplication()) {
+    spec = baseSpec
+    customTypes = MyJavaProto.getDefaultInstance().createCustomTypesForTypeAndSubTypes().toMap()
+  }
+}
+```
+
+For multiple messages and their submesages:
+```kotlin
+private fun Application.mainModule() {
+  // ...
+  install(NotarizedApplication()) {
+    spec = baseSpec
+    customTypes = MyJavaProto.getDefaultInstance().createCustomTypesForTypeAndSubTypes()
+      .plus(AnotherJavaProto.getDefaultInstance().createCustomTypesForTypeAndSubTypes()).toMap()
+  }
+}
+```
+
+### Example User
+
+The protobuf that is used on our endpoint
+```proto
+message User {
+  string id = 1;
+  string email = 2;
+  string mobile_phone = 3;
+  string name = 4;
+}
+```
+
+A custom serializer deserializer:
+```kotlin
+@OptIn(ExperimentalSerializationApi::class)
+object UserSerializer : KSerializer<User> {
+
+  override val descriptor: SerialDescriptor = buildClassSerialDescriptor("User") {
+    element("id", serialDescriptor<String>())
+    element("email", serialDescriptor<String>())
+    element("mobile_phone", serialDescriptor<String>())
+    element("name", serialDescriptor<String>())
+  }
+
+  override fun deserialize(decoder: Decoder): User {
+    return decoder.decodeStructure(descriptor) {
+      var id: String? = null
+      var email: String? = null
+      var mobilePhone: String? = null
+      var name: String? = null
+
+      loop@ while (true) {
+        when (val index = decodeElementIndex(descriptor)) {
+          CompositeDecoder.DECODE_DONE -> break@loop
+          0 -> id = decodeStringElement(descriptor, index)
+          1 -> email = decodeStringElement(descriptor, index)
+          2 -> mobilePhone = decodeStringElement(descriptor, index)
+          3 -> name = decodeStringElement(descriptor, index)
+          else -> throw   RuntimeException(
+            "Unexpected index field ${descriptor.getElementName(index)}"
+          )
+        }
+      }
+      // building the protobuf object
+      val user = User.newBuilder().apply {
+        id?.let { v -> this.id = v }
+        email?.let { v -> this.email = v }
+        mobilePhone?.let { v -> this.mobilePhone = v }
+        name?.let { v -> this.name = v }
+      }.build()
+      user
+    }
+  }
+
+  override fun serialize(encoder: Encoder, value: User) {
+    encoder.encodeStructure(descriptor) {
+      encodeStringElement(descriptor, 0, value.id)
+      encodeStringElement(descriptor, 1, value.email)
+      encodeStringElement(descriptor, 2, value.mobilePhone)
+      encodeStringElement(descriptor, 3, value.name)
+    }
+  }
+}
+```
+Setting the content type:
+```kotlin
+install(ContentNegotiation) {
+  json(Json {
+    encodeDefaults = false
+    // Combine the kompendium serializers with your custom java proto serializers 
+    serializersModule =
+      KompendiumSerializersModule.module + SerializersModule { 
+        serializersModule = SerializersModule {
+          contextual(UserSerializer)
+        }
+      }
+  })
+}
+```
+The installation of the noterized application:
+```kotlin
+install(NotarizedApplication()) {
+  spec = baseSpec
+  customTypes = User.getDefaultInstance().createCustomTypesForTypeAndSubTypes().toMap()
+}
+```
+Route configuration as you normally would with one exception which is `createType()` to create kotlin type from a javaClass.
+
+```kotlin
+private fun Route.userDocumentation() {
+  install(NotarizedRoute()) {
+    post = PostInfo.builder {
+      summary("My User API")
+      description("Create a user")
+      request {
+        requestType(User::class.createType())
+        description("My user creation object")
+      }
+      response {
+        responseCode(HttpStatusCode.OK)
+        responseType(CreateUserResponse::class.createType())
+        description("Returns simulation object")
+      }
+      canRespond {
+        responseCode(HttpStatusCode.NotFound)
+        responseType<String>()
+        description("Indicates that the user could not be found")
+      }
+    }
+  }
+}
+```
