As OpenGarage firmware supports OTA (over-the-air) update, you can upload the firmware through the web interface. At the homepage, find the Update or Update Firmware button and follow that to upload a new firmware. If your OpenGarage is in AP mode and not connected to any WiFi network yet, you can open http://192.168.4.1/update and that's the same interface.
Go to the doc folder to find the user manual as well as the API document for each firmware version.
