+While using Zapdos on the command line is the standard and recommended method for using the code and
+visualizing the results, a GUI is available for use through the [!ac](MOOSE) framework. Peacock is a
+general front end for [!ac](MOOSE) input file syntax, simulation, and visualiztion. General directions
+compatible with all [!ac](MOOSE)-based applications can be found [at this link](application_usage/peacock.md).
