+STM32MP135F Discovery Kit
+
+Intro
+=====
+
+This configuration supports the STM32MP135F Discovery Kit (DK)
+platform:
+
+  https://www.st.com/en/evaluation-tools/stm32mp135f-dk.html
+
+How to build
+============
+
+ $ make stm32mp135f_dk_defconfig
+ $ make
+
+How to write the microSD card
+=============================
+
+Once the build process is finished you will have an image called
+"sdcard.img" in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an microSD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Boot the board
+==============
+
+ (1) Insert the microSD card in connector CN15
+
+ (2) Plug a micro-USB cable in connector CN11 and run your serial
+     communication program on /dev/ttyACM0.
+
+ (3) Plug a USB-C cable in CN6 to power-up the board.
+
+ (4) The system will start, with the console on UART, but also visible
+     on the screen.
