+## Overview
+
+Push notifications enhance the Pixelfed experience by delivering real-time updates directly to users' devices. These notifications inform users about new followers, likes, comments, and other important interactions, keeping them engaged with their community.
+
+## Availability
+
+Currently, push notifications are limited to the official Pixelfed mobile applications. We plan to support web push and 3rd party applications in the future.
+
+
+## Instance Approval and API Key Requirement
+
+To enable push notifications on your Pixelfed instance, you must obtain manual approval and a unique API key from the Pixelfed team. This process helps maintain the integrity and performance of the push notification service across the network.
