+---
+
+# Notifications
+
+The Ente app can send notifications to notify you of an update, or just to
+remind you of some sweet or helpful memory at the right time.
+
+## New shared photos
+
+Receive notifications when someone adds a photo to a shared album that you're a
+part of.
+
+## "On this day" memories
+
+Receive reminders about memories from this day in previous years. These
+reminders will only be shown if there are enough photos taken across previous
+years of the specific day.
+
+## Birthday notifications
+
+Receive reminders when it's someone's birthday. Tapping on the notification will
+take you to photos of the birthday person. This requires you to first add a
+birthday to a person, and will only be shown if there are enough photos of that
+person.
+
+## Notification permission
+
+By default all notification categories are enabled if you give notification
+permission. You can disable all of the above notification categories from
+`Settings > Notifications`. Notifications currently only work on mobile.
