+`IUiNotificationService` is used to show toastr style notifications on the user interface.
+
+## Quick Example
+
+Simply inject `IUiNotificationService` to your page or component and call the `Success` method to show a success message.
+
+```csharp
+namespace MyProject.Blazor.Pages
+{
+    public partial class Index
+    {
+        public IUiNotificationService UiNotificationService { get; }
+
+        public Index(IUiNotificationService uiNotificationService)
+        {
+            UiNotificationService = uiNotificationService;
+        }
+
+        public async Task DeleteAsync()
+        {
+            //Delete entity
+            await UiNotificationService.Success("The product 'Acme Atom Re-Arranger' has been successfully deleted.");
+        }
+    }
+}
+```
+

+
+If you inherit your page or component from `AbpComponentBase` class, you can use the `Notify` property to access the `IUiNotificationService`.
+
+```csharp
+namespace MyProject.Blazor.Pages
+{
+    public partial class Index : AbpComponentBase
+    {
+        public async Task DeleteAsync()
+        {
+            //Delete entity
+            await Notify.Success("The product 'Acme Atom Re-Arranger' has been successfully deleted.");
+        }
+    }
+}
+```
+
+## Notification Types
+
+There are four types of pre-defined notifications;
+
+* `Info(...)`
+* `Success(...)`
+* `Warn(...)`
+* `Error(...)`
+
+All of the methods above gets the following parameters;
+
+* `message`: The message (`string`) to be shown.
+* `title`: An optional (`string`) title.
+* `options`: An optional (`Action`) to configure notification options.
+
+## Notification Configuration
+
+It is easy to change default notification options if you like to customize notifications. Provide an `action` to the `options` parameter and change the default values.
+
+```csharp
+await UiNotificationService.Success("The product 'Acme Atom Re-Arranger' has been successfully deleted.", options: (options) =>
+    {
+        options.OkButtonIcon = "custom-icon";
+        options.OkButtonText = L["CustomOK"];
+    });
+```
+
+List of the options that you can change by providing the `action` parameter.
+
+* `OkButtonText` : Custom text for the Ok button.
+* `OkButtonIcon` : Custom icon for the Ok button
