 # General Notes
 
-## Desktop
+## Project Hierarchy
 
-- The desktop GUI is based off of Java Swing.
+Forge is divided into 4 primary projects with additional projects that target specific platform releases.  The primary projects are:
 
-- Use the following build command to create and populate `forge-gui-desktop/target/forge-gui-desktop-<release-name>` for Linux and Windows:
+- forge-ai
+- forge-core
+- forge-game
+- forge-gui
 
-    `mvn -U -B clean -P windows-linux install`
+The platform-specific projects are:
 
-## Mobile
+- forge-gui-android
+- forge-gui-desktop
+- forge-gui-ios
+- forge-gui-mobile
+- forge-gui-mobile-dev
 
-The mobile GUI is based off of [libgdx](https://libgdx.badlogicgames.com/).  As with many other libgdx projects, there is a mobile-dev version "forge-gui-mobile-dev" that runs on the desktop but is separate and distinct from the 'desktop GUI' mentioned above.
+### forge-ai
+
+### forge-core
+
+### forge-game
+
+### forge-gui
+
+### forge-gui-android
+
+Libgdx-based backend targeting Android.  Requires Android SDK and relies on forge-gui-mobile for GUI logic.
+
+### forge-gui-desktop
+
+Java Swing based GUI targeting desktop machines.  
+
+Screen layout and game logic revolving around the GUI is found here.  For example, the overlay arrows (when enabled) that indicate attackers and blockers, or the targets of the stack are defined and drawn by this.
+
+### forge-gui-ios
+
+Libgdx-based backend targeting iOS.  Relies on forge-gui-mobile for GUI logic.
+
+### forge-gui-mobile
+
+Mobile GUI game logic utilizing [libgdx](https://libgdx.badlogicgames.com/) library.  Screen layout and game logic revolving around the GUI for the mobile platforms is found here.
+
+### forge-gui-mobile-dev
+
+Libgdx backend for desktop development for mobile backends.  Utilizes LWJGL.  Relies on forge-gui-mobile for GUI logic.
