+
+## Setup
+
+To enable notifications, simply add this self-configuring plugin package to your project:
+
+```sh
+ cds add notifications 
+```
+
+<img width="1300" alt="cds add notifications" style="border-radius:0.5rem" src="_assets/cdsAddNotifications.gif">
+
+## Usage
+
+In this guide, we use the [Incidents Management reference sample app](https://github.com/cap-js/incidents-app) as the base, to publish notifications.
+
+### Update Notification Configuration
+
+`cds add notifications` will add default configurations for notifications in the `package.json` file.
+
+<img width="1300" alt="Default Notification config" style="border-radius:0.5rem" src="_assets/packageJsonConfig.gif">
+
+#### **Notification Destination**
+
+As a pre-requisite to publish the notification, you need to have a [destination](https://help.sap.com/docs/build-work-zone-standard-edition/sap-build-work-zone-standard-edition/enabling-notifications-for-custom-apps-on-sap-btp-cloud-foundry#configure-the-destination-to-the-notifications-service) configured to publish the notification. In the `package.json` by default destination name `SAP_Notification` is added, you can modify the destination name that you are configuring.
+
+#### **Notification Types Path**
+
+When you run `cds add notifications`, it will add `notificationstype.json` file with template for a notification type in the project root folder.  You can add the notification types in the `notificationtype.json` file for sending the custom notification types.
+
+#### **Notification Type Prefix**
+
+To make notification types unique to the application, prefix is added to the type key. By default, `application name` is added as the prefix. You can update the `prefix` if required.
+
+### Add Notification Types
+
+If you want to send custom notifications in your application, you can add the notification types in the `notificationtype.json` file.
+
+Sample: If you want to send the notification when the new incident is reported, you can modify the `notificationtypes.json` as below:
+
+```jsonc
+[
+  {
+    "NotificationTypeKey": "IncidentReported",
+    "NotificationTypeVersion": "1",
+    "Templates": [
+      {
+        "Language": "en",
+        "TemplatePublic": "Incident Reported",
+        "TemplateSensitive": "Incident '{{name}}' Reported",
+        "TemplateGrouped": "New Incidents",
+        "TemplateLanguage": "mustache",
+        "Subtitle": "Incident '{{name}}' reported by '{{customer}}'."
+      }
+    ]
+  }
+]
+```
+
+### Update handlers to publish notification
+
+In the handler files, connect to the notifications plugin by:
+
+```js
+const alert = await cds.connect.to('notifications');
+```
+
+#### **Simple Notificaiton with title**
+You can use the following signature to send the simple notification with title
+```js
+alert.notify({
+  recipients: recipients,
+  priority: priority,
+  title: title
+});
+```
+#### **Simple Notificaiton with title & description**
+You can use the following signature to send the simple notification with title and description
+```js
+alert.notify({
+  recipients: recipients,
+  priority: priority,
+  title: title,
+  description: description
+});
+```
+#### **Custom Notifications with notification types**
+You can use the following signature to send the custom notification with pre-defined notification types.
+```js
+alert.notify({
+  NotificationTypeKey: 'IncidentCreated',
+  NotificationTypeVersion: '1',
+  Priority: 'NEUTRAL',
+  Properties: [
+    {
+      Key: 'name',
+      IsSensitive: false,
+      Language: 'en',
+      Value: 'Engine overheating',
+      Type: 'String'
+    },
+    {
+      Key: 'customer',
+      IsSensitive: false,
+      Language: 'en',
+      Value: 'John',
+      Type: 'String'
+    }
+  ],
+  Recipients: recipients
+});
+```
+
+### Sample Application with notifications
+
+#### **In Local Environment**
+In local environment, when you publish notification, it is mocked to publish the nofication to the console.
+

+
+#### **In Production Environment**
+
+Once application is deployed and integrated with SAP Build Work Zone, you can see the notification under fiori notifications icon!
