 # Main Makefile. This is basically the same as a component makefile.
 #
-# This Makefile should, at the very least, just include $(SDK_PATH)/make/component_common.mk. By default, 
-# this will take the sources in the src/ directory, compile them and link them into 
-# lib(subdirectory_name).a in the build directory. This behaviour is entirely configurable,
-# please read the ESP-IDF documents if you need to do this.
