+
+Additional Features and changes will be coming soon!
+
+## Updating the software / firmware
+
+To update the software on the board you can do two things.
+
+1. Use the fimware blob from our release section. To use this, unplug and turn off the module. Using something non conductivem press and hold the button on the RPI 2040 (The BootSelect Button) while powering on the unit via a micro usb cable. You should then see a mass storage drive appear on your computer. Drag the single uf2 file onto the drive. Then the unit should restart with the new firmware.
+
+2. You can also plug the unit into your computer via the micro usb and drag the contents of the Production/Software folder onto the mass storage drive. The unit should reboot when complete. Sometimes if your computer transfers the files too slow this can cause issues with the RPI rebooting before all the software is complete.
