 ##Description
 This application will communicate to a TbsShield equiped Arduino.  It will expose actions and graph the realtime results.
-See the Tbs4Rpm for a Arduino sketch that this project will communicate with.
+See the [Tbs4Rpm](https://github.com/deHarro/Tbs4Rpm) for a Arduino sketch that this project will communicate with.
 
 ##Install
 To install, clone this into your Vs projects folder, which will place it in a folder named Tbs4Rpm.  VS is not picky where you actually clone this project to on your computer and you may clone this into any folder you want.
