 You can also check out the [provided samples](https://github.com/ivaylokenov/MyTested.AspNetCore.Mvc/tree/master/samples) for real-life ASP.NET Core MVC application testing.
 
-Basically you can create a test case by using the fluent API the library provides. You are given a static `MyMvc` class from which all assertions can be easily configured.
+First we need to create a `TestStartup` class in the root of the test project in order to register the dependency injection services. The easiest way is to inherit from the web project's `Startup` class and replace some of the services with mocked ones by using the provided extension methods.

 Basically, MyTested.AspNetCore.Mvc throws an unhandled exception with a friendly error message if the assertion does not pass and the test fails.
