 ReactiveUI Source Generators automatically generate ReactiveUI objects to streamline your code. These Source Generators are designed to work with ReactiveUI V19.5.31+ and support the following features:
 
 - `[Reactive]` With field and access modifiers, partial property support (C# 13 Visual Studio Version 17.12.0), partial properties with initializer support (C# preview only)
-- `[Reactive(SetModifier = AccessModifier.Protected)]` With field and access modifiers, (Not Required for partial properties, configure set accessor with the property decalaration).
+- `[Reactive(SetModifier = AccessModifier.Protected)]` With field and access modifiers, (Not Required for partial properties, configure set accessor with the property declaration).
 - `[Reactive(Inheritance = InheritanceModifier.Virtual)]` With field and access modifiers. This will generate a virtual property.
-- `[Reactive(UseRequired = true)]` With field and access modifiers. This will generate a required property, (Not Required for partial properties, use required keyword for property decalaration).
+- `[Reactive(UseRequired = true)]` With field and access modifiers. This will generate a required property, (Not Required for partial properties, use required keyword for property declaration).
+- `[Reactive(nameof(RaiseProperty1), nameof(RaiseProperty2))]` With field and property changed notification for additional properties.
 - `[ObservableAsProperty]` With field, method, Observable property and partial property support (C# 13 Visual Studio Version 17.12.0)
 - `[ObservableAsProperty(ReadOnly = false)]` Removes readonly keyword from the generated helper field
 - `[ObservableAsProperty(PropertyName = "ReadOnlyPropertyName")]`
