+# Notifications
+
+With real-time notifications you stay informed and can take appropriate actions immediately.
+
+Notifications inform you about incoming assignments or requests, for example, when:
+
+- another user invites you to preview their work
+- when items are assigned for [your review](../content_management/workflow_management/editorial_workflow.md#review-queue)
+- when another user requests that you [release a lock](work_with_versions.md#release-locked-drafts)
+- when items are [sent to trash](copy_move_hide_content.md#remove-content)
+
+## Access notifications
+
+At the top of the main screen you can see a top bar.
+The top bar contains a notification icon.
+When you receive a new notification, a badge appears on the notification icon, with a number of notifications that require your attention, and a message appears on the screen to notify you of new notifications.
+
+![New notification message](new_notification_message.png "New notification message")
+
+If you have already received notifications and didn't act on then, a number of notifications on the badge increases when you receive another one. 
+
+![Notification icon on the top bar](img/top_bar_with_notification_icon.png "Notification icon on the top bar")
+
+Click the notification icon to view a short list with the most recent notifications, arranged from newest to oldest.
+Here, you can click certain notifications in the short list to act on them, according to their originator's request.
+
+You can click the three dots icon on the right side of each individual notification and mark it as read or delete it.
+You can also click **Mark all as read** to mark all notifications as read.
+
+![Short list of notifications](notifications_short_list.png "Short list of notifications")
+
+!!! note "Informative notifications"
+
+    Some notifications are informative only, and do not require your action.
+    An example could be an information that scheduled publication of a content item has been cancelled.
+
+## View all notifications in Notifications screen
+
+The short list holds a limited number of notifications.
+You can see all the notifications that you have received in the **Notifications** screen.
+
+1. In the top bar, click a notification icon. Then, at the bottom of the short list, click **View all notifications...**.
+
+    Here, you can see a list of notifications, together with information about their status and arrival date and time.
+
+    ![Notifications screen](img/notifications_screen.png "Notifications screen")
+
+    !!! note "List pagination"
+    
+        The list can take more than one screen. If it is so, you can click the arrows and numbers at the bottom of the screen to navigate the list.
+
+2. Narrow down the list of displayed notifications by selecting one or more of the following filters:
+
+    - **Notification type**: for example, content item review request
+    - **Status**: unread or read
+    - **Date and time**: start and end of date range within which the notification was received
+
+    ![Notification filters](img/notifications_filters.png "Notification filters")
+
+3. Click **Apply** to confirm your choices.
+
+4. To clear all the filters, click **Clear filters**.
+
+### Act on notifications
+
+In the notification screen, you can act on the notification to fulfill the request of the originator.
+
+To act on a notification, find it in the notifications list and click an icon next to the notification's date and time.
+Depending on the context, the icon can be called differently, for example, **Go to content** or **Accept request**.
+
+### Delete notifications or change their status
+
+You may want to change the status of multiple or individual notifications in the **Notifications** screen, or even delete them completely.
+
+1. Use filters to find the notifications that you want to delete or change their status.
+
+2. To toggle the status of an individual notification, find it in the notifications list and, in its line, next to the notifications date and time, click an envelope icon.
+
+3. To delete multiple notifications at once or mark them as read, in the **Notifications** screen:
+
+    - select checkboxes next to notifications that you want to process
+    - at the top of the list, click **Mark as read** or **Delete**.
