+* In here we've specified the Elsa Server Api's assembly by using the `AddAssemblyOf<>` extension method to register the required services (controllers).

 * We don't need to register our workflows one by one anymore. Because now we use `.AddWorkflowsFrom<Startup>()`, and this registers workflows on our behalf. 
 
 * As you may notice here, we use a section named `Elsa` and its sub-sections from the configuration system but we didn't define them yet. To define them open your `appsettings.json` and add the following Elsa section into this file.
