You can update the firmware on a device by loading a binary onto the SD card and inserting it into the RTK Surveyor (see more information [here](https://learn.sparkfun.com/tutorials/sparkfun-rtk-surveyor-hookup-guide/firmware-updates-and-customization)) or by using the following CLI:
+This folder contains the various firmware versions for RTK Products (Surveyor, Express, Express+, and Facet). 
+
+Updating the firmware can be achieved by using one of the following methods:
+
+* Load the firmware on an SD card, then use a serial terminal with *Firmware Upgrade* menu
+* Load the firmware over WiFi when the device is in WiFi AP Config Mode
+* Use the [Windows GUI](https://github.com/sparkfun/SparkFun_RTK_Firmware/Uploader_GUI) and a USB cable. (This method is python based which can also be used on Linux, Mac OS, and Raspberry Pi)
+* Use the command line *batch_program.bat* (see below)
+
+The SD method is generally recommended. For more information see [here](https://learn.sparkfun.com/tutorials/sparkfun-rtk-surveyor-hookup-guide/firmware-updates-and-customization).
