+Updating Firmware
-------
+-----------------
-
-You can upload a new version of the firmware.
-Reset the device, 
-and select the "Update" button instead of configuring WiFi.
-Then you can upload the new .bin firmware file.
-
-You may have to reconfigure networking after this.

-### Uploading from CLI
