 For this reason, we have created a hierarchy of service interfaces that can be used to get the
 exact implementation you require. Below is a table outlining these interfaces:

  In order to take advantage of these interfaces you first need to inject the service for each implemented interface. 
  Using Autofac, as an example, this is simply:
 
 ```csharp
 public class MyResourceService : ICreateService<MyResource>, IDeleteService<MyResource> {
- //...
+   // ...
 }
+```
 
+```csharp
 public class Startup {
   public IServiceProvider ConfigureServices(IServiceCollection services) {
-    // ...
     builder.RegisterType<MyResourceService>().AsImplementedInterfaces();
-    // ...
   }
 }
 ```
