+###How to use:
 
 1. Download the source from the git https://github.com/Makeblock-official/Makeblock-Libraries
 
-2. copy the makeblock folder to your arduino default library. Your Arduino library folder should now look like this 
-   (on Windows): [arduino installation directory]\libraries\makeblock\src
-   (On MACOS): [arduino Package Contents]\contents\Jave\libraries\makeblock\src

 5. Depending on the type of board you're using, you need to modify the header file to match.
