 Programming and Debugging
 *************************

 Flashing
 ========
 
-Flashing Zephyr onto the ``adafruit_feather_nrf52480_express`` board is possible
-using an external programmer. The programmer is attached to the SWD header.
+Flashing Zephyr onto the ``adafruit_feather_nrf52480`` board requires
