+
+## Update Modulino firmware in Arduino IDE
+
+1. Connect the Modulino to your Arduino UNO R4 WiFi.
+
+2. Connect the board to your computer and open Arduino IDE.
+
+3. [Go to the Library Manager](https://support.arduino.cc/hc/en-us/articles/5145457742236-Add-libraries-to-Arduino-IDE) and install the [Modulino](https://www.arduino.cc/reference/en/libraries/modulino/) and [ArduinoGraphics](https://www.arduino.cc/reference/en/libraries/arduinographics/) libraries.
+
+4. In the top menu bar, open **File > Examples > Modulino > Utililities > FirmwareUpdater**.
+
+5. Click ![Upload button](img/symbol_upload2.png) **Upload** to upload the sketch to your Arduino UNO R4 WiFi.
+
+6. The firmware update is complete when the sketch is successfully uploaded to the board and the text `PAS` is displayed on the LED matrix.
+
+7. You can now test the Modulino by uploading an example from **File > Examples > Modulino**.

+## Update Modulino firmware in Arduino Cloud Editor
+
+1. Connect the Modulino to your Arduino UNO R4 WiFi.
+
+2. Connect the board to your computer and [open the Cloud Editor](https://support.arduino.cc/hc/en-us/articles/13809101080732-Open-the-Cloud-Editor).
+
+3. Go to the **Examples** tab on the left-side panel, and select **From Libraries**.
+
+4. Search for "Modulino" and open **Modulino > Utililities > FirmwareUpdater**.
+
+5. Copy the "FirmwareUpdater" example to a new sketch.
+
+    !["Examples" tab in Cloud Editor showing Modulino examples, with 'FirmwareUpdater' selected and 'Copy in your sketches' highlighted](img/modulino_firmwareUpdater.png)
+
+6. Click ![Upload button](img/symbol_upload_cloud.png) **Upload** to upload the sketch to your Arduino UNO R4 WiFi.
+
+7. The firmware update is complete when the sketch is successfully uploaded to the board and the text `PAS` is displayed on the LED matrix.
+
+8. You can now test the Modulino by [importing a Modulino Template](https://support.arduino.cc/hc/en-us/articles/14826942993308-Import-an-Arduino-Cloud-Template).
