 ## Configuration
 
 This integration is not user configurable.
+
+## Re-installing the firmware using the Silicon Labs Web Flasher
+
+The Home Assistant Connect ZBT-1 ships with a full-fledged Zigbee firmware. At this point, there are no known issues with the factory-flashed firmware.
+
+Normally, there is no need to re-install the firmware. Firmware updates for the Connect ZBT-1 are natively supported in Home Assistant 2025.4 and newer if you are running the ZHA integration or OTBR.
+
+If your Home Assistant installation has no add-ons available, you can use the web flasher below to install the latest firmware version for Home Assistant Connect ZBT-1 directly from your browser over USB.
+
+### Prerequisites
+
+- Firmware update through web flasher is only available for Home Assistant SkyConnect devices and for Home Assistant Connect ZBT-1 devices purchased after October 20, 2024.
+
+### To re-install the firmware
+
+1. Plug in your Connect ZBT-1 to your computer.
+2. Select the **Connect** button below.
+
+    <script type="module" src="https://unpkg.com/@nabucasa/sl-web-tools@0.10.1/dist/web/nabucasa-zigbee-flasher.js?module"></script>
+    <nabucasa-zigbee-flasher manifest="/static/firmware/connect-zbt-1/manifest.json"></nabucasa-zigbee-flasher>
+
+3. Select the firmware version you want to install.
