+# This script uses the arduino-cli to compile the arduino sketches using command line (without Arduino IDE).
+# It is very useful to check the library on multiple board types  after bug fixes and improvements. 
+# It runs on a MacOS but you can port it to Linux o Windows easily.
+# Some compilation results (bin and hex files) will be stores in your Download directory (/Users/<username>/Downloads/hex)
+# ATTENTION: be careful with --output-dir arduino-cli option. Before compiling, this option removes all the contents of the last level folder. 
+#            For example: if you use "--output-dir ~/Downloads", all the current content of the Downloads folder will be lost. 
+#                         if you use "--output-dir ~/Downloads/hex", all current content of the hex folder will be lost and the Downloads 
+#                         content will be preserved.
