+__Installation
+For a thorough wiki on installing a Universal Robot, [this wiki](http://wiki.ros.org/universal_robot) will likely be a good place to start. If you are also working with most newer versions of UR software (v3.x and up) there is a strong likelihood that you will require the newer ```ur_modern_driver``` ([found here](https://github.com/ThomasTimm/ur_modern_driver)) which has an in detail explanation of how to install/run your UR arm.
 
 __Installation from Source__ 
 There are releases available for ROS Hydro and ROS Indigo. However, for the latest features and developments you might want to install from source.
