+### DISCLAIMER
+### This is an example Makefile and it MUST be configured to suit your needs.
+### For detailed explanations about all of the available options, please refer
+### to https://github.com/sudar/Arduino-Makefile/blob/master/arduino-mk-vars.md
+
+### How to setup a project using a board definition provided by the 3rd party
+### =========================================================================
+
+### Some vendors provide definitions/configuration of their boards separately,
+### as so-called addon packages. Originally, they are supposed to be used in
+### the Arduino IDE but they can be used with Arduino-Makefile as well:
+
+### 1. get the package from the vendor
+###    if they provide .json file, look into it and take the URL of the package
+###       archive from there
+###
+### 2. extract the package into your ARDUINO_SKETCHBOOK directory
+###    you have to end with the directory structure like this, in your
+###    ARDUINO_SKETCHBOOK directory (sparkfun is the vendor name):
+
+###        hardware/
+###        ├── sparkfun/
+###        │   └── avr/
+###        │       ├── boards.txt
+###        │       ├── bootloaders/
+###        │       ├── driver/
+###        │       ├── platform.txt
+###        │       ├── signed_driver/
+###        │       └── variants/
+
+### 3. Create this Makefile (use your vendor/package name)
+
+###        ALTERNATE_CORE      = sparkfun
+###        include ~/Arduino-Makefile/Arduino.mk
+
+### 4. run 'make show_boards'
+###    check that you can see (only) boards provided by this vendor
+
+### 5. select the name of your board
+###    and add a line "BOARD_TAG = ...." to your Makefile
+
+### 6. if your board has more cpu variants, run 'make show_submenu'
+###    to see them; select your one and add a line "BOARD_SUB = ...."
+###    to your Makefile
+
+#####
+
+### The basic configuration should be done now.
+### The example follows:
+
+ARDUINO_SKETCHBOOK  = $(HOME)/sketchbook
+ALTERNATE_CORE      = sparkfun
+BOARD_TAG           = promicro
+BOARD_SUB	    = 8MHzatmega32U4
+include $(ARDMK_DIR)/Arduino.mk
