+# Installation of Micropython .bin on a ESP8266
+Before we can program and use a ESP8266 with python, we need to flash the firmware 
+to MP - a Mirco Python environment especially designed for these microprocessors
+
+We need to dowload the latest MP binary. At the time of writing:
+
+    wget https://micropython.org/resources/firmware/esp8266-1m-20220618-v1.19.1.bin
+
+Then, we need to flash the software to the microcontroller. A script that helps 
+us with this task is called esptool.py which can be downloaded from [HERE|https://github.com/espressif/esptool]:
+
+    esptool.py --port /dev/ttyUSB0 erase_flash
+    esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dout 0 esp8266-1m-20220618-v1.19.1.bin
