 an ISP (in system programmer) to do the debugging. This isn't an issue because
 all of the afore mentioned devices have ISP capabilities, but it requires some
 additional steps to get back normal operation after debugging:
- * flash a new arduino bootloader on the device, e.g. [this one](https://raw.

 In contrast to normal use (USB only), for debugging there are two separate
 wiring changes to do:
-* connecting the ISP headers (picture: orange cables).
-* connecting the JTAG header to the respective pins on the Arduino (picture:
-blue cables)
+* connecting the ISP headers
+* connecting the JTAG header to the respective pins on the Arduino
 
 Connecting the ISP headers is straight forward: Pin1 on the Dragon connects
 to Pin1 on the Arduino Mega2560 and so on.
