-## 📢 Auto Alerts(WIP)
+## 3. <a name='SystemNotifications'></a>📢 System Notifications
+
+The infrastructure team uses System Notifications to automatically surface important operational notifications in the Konflux UI.
+
+These notifications are generated from monitoring systems or automation scripts as Kubernetes ConfigMaps.
+
+The Konflux UI detects and displays these notifications to inform users about system-wide conditions.
+
+### 3.1. <a name='NotificationJSONFormat'></a>✅ **Notification JSON Format**
+
+System notifications are stored as Kubernetes ConfigMaps in the `system-notifications/` directory.
 
-We enables the infrastructure team to automatically surface specific operational issues or warnings in the Konflux UI.
+Each ConfigMap contains notification data in the `notification-content.json` field as JSON.
 
-These alerts would be auto-generated from monitoring systems or automation scripts, written as Kubernetes ConfigMaps, and automatically picked up by the Konflux UI to inform users of system-wide conditions.
+<strong>Key points:</strong>
 
-### ✅ Alert YAML Format
+- The JSON payload supports these fields for each notification object:
 
-Each file under auto-alerts/ must be a valid Kubernetes ConfigMap, including at minimum:
+  - <strong>title (optional)</strong>: A short heading.
+  - <strong>summary (required)</strong>: A brief, user-facing message displayed as the notification content.
+  - <strong>type (required)</strong>: It sets the bell icon. Allowed values: `info`, `warning`, or `danger`.
+
+- Payload structure:
+
+  We recommend using <strong>a single JSON object representing one notification</strong> in `notification-content.json`.
+
+  However, <strong>a JSON list (array) of notification objects is also allowed</strong> if multiple notifications need to be included in one ConfigMap.
+
+### 3.2. <a name='ExampleNotificationConfigMap'></a>✅ **Example Notification ConfigMap**
 
 ```yaml
 apiVersion: v1
 kind: ConfigMap
 metadata:
-  name: konflux-auto-alert-xyz
+  name: konflux-system-notification-xyz
   namespace: konflux-info
   labels:
-    konflux-auto-alert: "true" # Required. UI filter alerts out by this label.
+    konflux.system.notification: "true"
 data:
-  auto-alert-content.yaml: |
-    enable: true
-    summary: "Builds are delayed due to maintenance"
-    type: "warning"
+  notification-content.json: |-
+    {
+      "summary": "Builds are delayed due to maintenance",
+      "type": "warning",
+      "title": "From Builds Service"
+    }
 ```
 
-🔐 The data.banner-content.yaml should follow the schema defined in `auto-alert-schema.json`
+### 3.3. <a name='NotificationContentValidation'></a>✅ **Notification Content Validation**
 
-### Folder Structure
+To ensure consistency, a GitHub workflow named `notification-validate` automatically checks that all ConfigMaps in the `system-notifications` folder include the required labels and validates all `notification-content.json` objects against the schema defined in [notification-schema.json](./notification-schema.json).
+
+**When does it run?**
+
+- On any pull request that changes:
+  - `notification-schema.json` (schema definition)
+  - Any `yaml` file defined under `system-notifications`
+
+**What does it check?**
+
+- Ensures the JSON structure matches the schema (e.g., required fields, allowed values).
+- Ensure the configmaps are labelled well.
+- Prevents invalid or misconfigured notifications from being merged.
+
+**How to fix validation errors?**
+
+- Review the error message in the PR checks.
+- Compare your changes with the [schema](./notification-schema.json) and your labels.
+
+### 3.4. <a name='FolderStructure'></a>✅ **Folder Structure**
+
+Notifications are organized under the `system-notifications/` directory:
 
 ```bash
 
-auto-alerts/   # Alert ConfigMaps (one file = one alert)
+system-notifications/
 .
-├── alert-1.yaml           # Fully valid ConfigMap YAML
-├── alert-2.yaml
-└── kustomization.yaml     # Auto-generated, includes all alert YAMLs
+├── notification-1.yaml  # A ConfigMap representing one notification
+├── notification-2.yaml
+└── kustomization.yaml   # Auto-generated, includes all notifications YAMLs
 
 ```
+
+When there are no active notifications, both the `system-notifications/` folder and its reference in the parent `kustomization.yaml` should be removed automatically to avoid kustomize errors.
+
+### 3.5. <a name='UIBehavior-1'></a>✅ **UI Behavior**
+
+- The UI discovers and filters notifications by detecting ConfigMaps labeled with
+  `konflux.system.notification: "true".`
+- When a valid notification ConfigMap exists, its notification will be shown in the UI.
+- To remove a notification from the UI, the corresponding ConfigMap must be deleted or renamed so it no longer matches the label.
+- When multiple notifications exist, the UI lists them ordered by their creation time (`creationTimestamp`), <strong>showing the most recent first</strong>.
+- The `type` field control the notification icon shown before the title in the Notification Drawer.
+- If the `title` field is omitted in the JSON, it falls back to using component.metadata.name as the default in the UI.
+- We leveraged [PatternFly Notification Drawer (v5)](https://v5-archive.patternfly.org/components/notification-drawer/html/#ws-core-c-notification-drawer-basic) and [Notification Badge (v5)](https://v5-archive.patternfly.org/components/notification-badge) components to implement the UI, following their design principles for consistency and usability.
+- All notifications are always shown as unread. There is no backend tracking for notification state, so <strong>`read/unread` functionality is not supported</strong>.
+
+### 3.6. <a name='WhentoAddorRemoveNotifications'></a>✅ **When to Add or Remove Notifications**
+
+<strong>These notification ConfigMaps are automatically generated or removed</strong> by monitoring or scripting systems based on current system status.
+
+- Add a notification:
+
+  1. Generate a new ConfigMap YAML file under `system-notifications/`.
+  2. Refresh the `kustomization.yaml` in that folder to include the new file.
+  3. If the folder does not exist (e.g., no prior notifications), create it and its `kustomization.yaml`, and ensure the parent kustomization includes it.
+
+- Remove a notification:
+
+  1. Delete the corresponding ConfigMap YAML file from `system-notifications/`.
+  2. Refresh `kustomization.yaml` to remove the reference.
+  3. If no notifications remain, delete the `system-notifications/` directory and remove its reference from the parent kustomization.
+
+⚙️ Note: <strong>These add/remove operations are expected to be automated</strong>. Manual edits should only be done in emergencies or for debugging.
