 The Nucleo-L031K6 is a board from ST's Nucleo family supporting ARM Cortex-M0
 STM32L031K6T6 microcontroller with 8KiB of RAM and 32KiB of Flash.
 
+## Pinout
 
-## Flashing the Board Using ST-LINK Removable Media
-
-On-board ST-LINK programmer provides via composite USB device removable media.
-Copying the HEX file causes reprogramming of the board. This task
-could be performed manually; however, the cpy2remed (copy to removable
-media) PROGRAMMER script does this automatically. To program board in
-this manner, use the command:
-```
-make BOARD=nucleo-l031k6 PROGRAMMER=cpy2remed flash
-```
-@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
-      can be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
