In this chapter the annotation based approach of adding documentation to a service was introduced, followed by the possibilities to customize the output of this documentation. Next, the Swagger and Postman features were introduced to provide a sandbox for testing your service, followed by the built-in capability to map natural evolution of an API with versioning. Finally, the validation framework of ServiceStack was introduced and finished off with querying this framework to publish the validation rules.

In the next chapter, we will look into ways of extending ServiceStack, how to write a plugin, and other points for extensions.
