+# This file contains common pin mappings for the 2018 Creality
+# Ender 3. To use this config, the firmware should be compiled for the
+# AVR atmega1284p.
+
+# Note, a number of Melzi boards are shipped with a bootloader that
+# requires the following command to flash the board:
+#  avrdude -p atmega1284p -c arduino -b 57600 -P /dev/ttyUSB0 -U out/klipper.elf.hex
+# If the above command does not work and "make flash" does not work
+# then one may need to flash a bootloader to the board - see the
+# Klipper docs/Bootloaders.md file for more information.
+
+# See docs/Config_Reference.md for a description of parameters.
