 ## Annotation Reference
 
+### `@injectable`
+
+```dart
+@injectable()
+class MyWidget { ... }
+```
+Marks a class as injectable for CherryPick DI. The code generator will generate a mixin to perform automatic injection of fields marked with `@inject()`.
+
+---
+
+### `@inject`
+
+```dart
+@inject()
+late final SomeService service;
+```
+Applied to a field to request automatic injection of the dependency using the CherryPick DI framework.
+
+---
+
+### `@scope`
+
+```dart
+@inject()
+@scope('profile')
+late final ProfileManager manager;
+```
+Specifies the scope from which the dependency should be resolved for an injected field.
+
+---

 ### `@module`
 
 ```dart
 @module()
-abstract class AppModule extends Module {}
+abstract class AppModule {}
