+About Chest GUI
+=====
+
+A chest GUI is basically a dynamic menu that uses items and the standard chest layout to present a list of options in game.
+
+These items cannot be removed from the chest and the click event is instead passed on as a ChestGUIEvent. Because the mod requesting this might not be on the client, the event is sent in both locations by utilizing a network packet. 
+
+
+
+ChestGUIEvent
+====
+
+This event is the parent of several other events.
+
+OptionInteractEvent
+----
+This event gets dispatched on both the client and server when a option is interacted with. 
+
+OptionUpdateEvent
+----
+To be sent by the mod originating this dynamic menu. This event will instruct the ChestGUI to update a item, or multiple items after a interaction, or something else occuring. If the GUI is not open, this event gets ignored. This event should only be sent when we know the GUI is actually open!
