+## Model serializers extensions : since ver 1.2.6
+Since ver 1.2.6 there is a possibility to use a custom JSON serializers/deserializers in generated code. By default, there is used
+`StandardJsonSerializerExtension` which is generating code based on standard JavaScript `JSON` object (`JSON.stringify` & `JSON.parse`).
+`Json5ModelSerializerExtension` extension allows to use `JSON5` serializer. Following code snippet is showing how to configure generator:
+
+```
+    ImplementationGenerator implementationGenerator = new Angular4ImplementationGenerator();
+    implementationGenerator.setSerializationExtension(new Json5ModelSerializerExtension());
+    restClassesConverter = new SpringRestToTsConverter(implementationGenerator);
+    tsGenerator.setRestClassesConverter(restClassesConverter);
+
+    tsGenerator.generate(javaPackageSet, OUTPUT_DIR_PATH);
+``` 
+To provide own JSON serializers/deserializers extension, user should implement `ModelSerializerExtension` interface

 ## Nullable types
 TypeScript has s great feature to warn about cases where value could be null. To use it TS compiler option must be set
 `strictNullChecks` and proper fields in model set as nullable or proper parameters in methods which make REST calls.
