+A collection of documentation, tricks and tips regarding the STM32 Nucleo-64 Board (development kit).
 
-We will mainly cover the `stm32f401re` and `stm32f411re` as these models.
+We will mainly cover the `stm32f401re` and `stm32f411re` as these models (main difference is the higher maximum clock frequency of the `stm32f411re`).

+## Stlink inteface
+The nucleo-64 platform has an onboard `stlink-v2.1` SWD interface (programmer) supported by `openocd`. By default the programmer is connected to the target (`stm32f401re` or similar). 
+
+---
+### Programming external targets
+You may use the board as a programmer (connector `CN4` SWD), in that case you should remove the `CN3` jumpers, and optionally desolder `SB15` (SWO) and `SB12` (NRST). See board documentation for details.
