 1. It is recommended to upgrade Java to the [latest version](https://www.java.com/en/download/)
 1. Download the [STM32 Core](https://github.com/rogerclarkmelbourne/Arduino_STM32/archive/master.zip) and copy the Arduino_STM32 folder to:
-  - OSX: ```Arduino.app/Contents/Java/hardware```  (you can open Arduino.app by Ctl Clicking on Arduino.app and selecting "Show Package Contents") 
-  - Windows: ```C:\Program Files (x86)\Arduino\hardware``` 
-  - Make sure the folder tree structure is like this .....\hardware\Arduino_STM32\.....and **NOT** ...... \hardware\Arduino_STM32-master\Arduino_STM32-master\......So move the folders /rename accordingly.
