-### RESET pin configuration
-
-On many (all?) nrf52840dk boards, the reset pin is not configured out-of-the box.
-This means, that simply nothing happens if the RESET pin is pressed. To change
-this, RIOT provides a little tool in `dist/tools/nrf52_resetpin_cfg`.
-
-Simply compile, flash, and run that tool on your board, and the reset pin should
-work for the time being.

 ## Flash the board
