+// Notes:
+// This file adds support for the Micronucleus bootloader V1 and V2,
+// so you do no longer need the Micronucleus command-line utility.
+//
+// This bootloader is typically used on small ATtiny boards,
+// such as Digispark (ATtiny85), Digispark Pro (ATtiny167),
+// and the respective clones.
+// By default, it bootloader uses the VID/PID 16d0:0753 (MCS Digistump).
+//
+// As the micronucleus bootloader is optimized for size, it implements
+// writing to flash memory only. Since it does not support reading,
+// use the -V option to prevent avrdude from verifing the flash memory.
+// To have avrdude wait for the device to be connected, use the
+// extended option '-x wait'.
+//
+// Example:
+// avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex
