+# Client Automatic Updates
+
+The Automatic Updates feature allows the NetBird client to automatically update itself when a new version is available. This ensures that users always have the latest features and security patches without needing to manually download and install updates.
+
+<Note>
+    Minimum supported agent version: <strong>v0.61.0</strong>.
+    This or higher version must also be installed on the peers you need to Automatically Update.
+</Note>
+
+<Note>
+    This feature also requires an upgraded NetBird Management server.
+    If you're self-hosting NetBird, ensure your server is updated to version <strong>v0.61.0</strong>, which adds support for Automatic Updates.
+</Note>
+
+<Note>
+    This feature is currently under active development and will continue to evolve. Future releases will add Linux support, and handling for long-running peers.
+</Note>
+
+## Enable Automatic Updates
+
+![Automatic Updates](/docs-static/img/how-to-guides/auto-update/dashboard.png)
+
+To enable client auto updates, navigate to [Settings &raquo; Clients](https://app.netbird.io/settings) and enable 'Automatic Updates'.
+
+You can either:
+
+* Update to latest stable version.
+* Update to a specific version.
+
+Once enabled, NetBird clients will automatically check for updates when connecting via the UI and install the specified version if the current version is older than the specified version.
+
+
+## How it works
+
+1. **User-Initiated Connection**: When a Peer connects to Management, it will receive the current Automatic Updates settings.
+2. **Version Check**: The Peer will compare its current version with the version specified in the Automatic Updates settings.
+3. **Update Process**:
+    1. If the Peer is running an older version than specified, it will show a notification to the user indicating that an Automatic Update is under way.
+    2. Client will then download the update package from the official NetBird repository.
+    3. The Peer will then install the update and restart itself to apply the changes.
+
+## Supported Platforms
+
+Automatic Updates are supported on the following platforms only:
+- Windows
+- macOS (with PKG installer)
+
+Linux support is not available at this time due to the variety of distributions and package managers. A future release may include support for popular distributions.
+
+## Backward and Forward Compatibility
+
+* If Management server version &lt; v0.61.0, clients will **not** automatically update.
+* If Management server version &gt;= v0.61.0, NetBird clients with version &gt;= v0.61.0 will automatically update according to the Automatic Updates settings.
+
+## Notes
+
+1. Automatic Updates will be set to "disabled" by default.
+2. If the Peer is unable to download or install the update (e.g., due to network issues), it will show an error notification but will not retry until the next restart.
+3. For long-running Peers, a future release may include support for periodic update checks during runtime.
+4. All notifications related to Automatic Updates will be shown only if NetBird UI is running and Notifications are enabled.
