# Sample Makefile to build simple project.

# This Makefile expect all source files (.c) to be at the same level, in the
-# current working directory.
+# $(SRC_PATH) directory.
+#
+# This Makefile expect all embedded library files (.c) to be at the same level, in the
+# $(LIBRARY_PATH) directory.
#
# It will automatically generate dependencies, compile all files, and produce a
-# binary using the provided name.
+# binary using the provided name linked against the library if necessary.
#
# Set BINARY_NAME to the name of the binary file to build.
-# Set BUILD_TYPE to either debug or release
+# Set LIBRARY_NAME to the name of the library file to build.
+# The default path for the library code and object is lib.
+# By default the linker will look for $(BINARY_NAME) library name.
+# Set BUILD_TYPE to either debug or release.
