If you receive an error that esptool.py only supports Python 2.x try running again with the '''pip2''' command instead of pip (likely your system is using Python 3 and the pip command is getting confused which version to use).

Where /path/to/ESP8266 is the path or name of the serial port that is connected to the ESP8266.  The exact name of the device varies depending on the type of serial to USB converter chip so you might need to look at the serial ports with and without the device connected to find its name.

Once the tool finishes flashing the firmware (you'll usually see a blue light on the ESP8266 module flashing during this process) press the RESET button on the ESP8266 board or disconnect and reconnect it to your computer.  You should be all set to start using the latest MicroPython firmware on the board!
