+## Registry (and Dependency Injection)
 
 [Registry](../core/src/Registry.kt) and it's default implementation - `DependencyInjectingRegistry` - provide
 a simple way to register and require both Klite components and repositories/services of your application.
 
 `DependencyInjectingRegistry` is used by default and can create any classes by recursively creating their constructor
 arguments (dependencies).
 
+You can use `register<MyInterface>(MyImplementation::class)` or `register<MyImplementation>()` to register a specific implementation that needs to be used for an interface.
+
+See [it's tests](test/klite/DependencyInjectingRegistry.kt) for usage examples.
+
 ## Decorators
 
 You can add both global and context-specific [decorators](src/klite/Decorators.kt), including `Before` and `After` handlers.
