-Hello world!
+Getting Started - Ground Station
+================================
+
+The Ground Station as a whole allows all the different systems and hardware to
+communicate with each other. The Ground Station has four main components including:
+	* Command Line Interface (CLI)
+	* Graphical User Interface (GUI)
+	* Frontend
+	* Backend
+Both the CLI and GUI are user interfaces. The GUI uses all the same commands and the 
+CLI but has extra functionality. The GUI shows the controls graph, provides extra
+navigation help, and will soon support real time graphing of the data. The Frontend
+does all the reading from and writing to the backend via a socket connected to the 
+backend. The backend is primarily a server that manages all connections and where all
+data passes through between the VRPN (Camera System), the quad, and user interfaces.
+**Figure 1** shows the main components and their interaction. Both user interfaces use
+the frontend to manage the writing and parsing of return messages from the backend.
