+## Overview
+
+The STM32L476GDISCOVERY is an evaluation board with the ARM Cortex-M4 based
+ultra-low power microcontroller STM32L476VGT6 with 128KiB of RAM and 1MiB of
+ROM Flash.

+
+## 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=stm32l476g-disco 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).
+
+## Accessing RIOT shell
+
+Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface,
+provided by integrated ST-LINK programmer. ST-LINK is connected to the
+microcontroller USART2.
+
+The default baud rate is 115200.
