+The OpenBCI GUI is OpenBCI's powerful software tool for visualizing, recording, and streaming data from the OpenBCI Boards. Data can be displayed in live-time, played back, saved to your computer in .txt or .bdf/.edf format, as well as streamed in live-time to third-party software such as MATLAB.
 It can be launched as a standalone application or as a sketch from Processing (a Java-based programming language). In this guide, we will cover both scenarios.
 
 ## Hardware/Driver Setup for OpenBCI_GUI
 
-Shown below are the three OpenBCI Boards that can be used with the OpenBCI GUI.
+The Ganglion, Cyton, and CytonDaisy Boards are compatible with the OpenBCI GUI.

+**Most users should start by downloading the [standalone GUI](https://www.openbci.com/downloads). The Processing IDE is for adding features, modifying existing code, or testing development versions.**
 
 The OpenBCI GUI is built using [Processing 4](https://processing.org/), a popular, Java-based creative coding framework. If you are interested in adding features or modifying the existing code, it is really easy to do so if you are familiar with Java. If you're not familiar with Java, don't fret! Processing is one of the easiest software packages to pick up as a beginner coder.
