+This toolset helps to split serial communication interface into 2 ACM ports. 
+
+### Prepating and Flashing
+- To prepare *.bin or *.elf use next command
+`make SERIALNUM-{ID}`
+
+- Connect the programmator pins to you MC according to the datasheet or silkprint
+
+- Upload the firmware to the controller 
+flash write {PATH} 0x8000000
+
+- If everything works correctly, you can connect you MC to USB port and check if your Serial port with the setted ID
+```
+$ ls -la /dev/serial/by-id/usb-*
+ 
+ /dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_ComPort_{ID}-if00 -> ../../ttyACM0
+ /dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_ComPort_{ID}-if02 -> ../../ttyACM1
+```
+
+###for Linux
+- You should install first an open source tools from the [(Link)](https://github.com/stlink-org/stlink) and all the requirements for it
