+--------------------------------------- Instructions ---------------------------------------
+
+------- Require this in your script like so: 
+
+-- self.GameIntensityCalculator = require("Activities/Utility/GameIntensityCalculator");
+-- self.GameIntensityCalculator:Initialize(Activity, bool newGame, bool verboseLogging, number intensityValuePerHPBarLost, number intensityDegradationRatePerSecond);
+
+-- Call self.GameIntensityCalculator:UpdateGameIntensityCalculator() every frame.
+
+-- The main update function will return an intensity number between 0 and 1.
+-- This corresponds to how much damage has been dealt directly within all the player's views.
+-- Use the two number arguments to control how the intensity value rises and falls.
+-- One "HP Bar" is considered a standard 100 HP.
+
+------- Saving/Loading
+
+-- Saving and loading requires you to also have the SaveLoadHandler ready.
+-- Simply run OnSave(instancedSaveLoadHandler) and OnLoad(instancedSaveLoadHandler) when appropriate.
+
+--------------------------------------- Misc. Information ---------------------------------------
