+Within the LUA environment you can use events to react to certain things, such as the profile being updated or key being pressed. 
+
+To use events you need to subscribe to them. You can subscribe to the same event more than once if you want.  
+The examples below show how subscribing works.
+
+### ProfileDrawing
+Triggers whenever the profile is being drawn
+#### Parameters
+```lua
+profile profile, profileDrawingEventArgs eventArgs
+```
+#### Event Arguments
+- **DataModel:** An object containing the current DataModel. *(TODO: DataModel explaination)*
+- **Preview:** A boolean indicating whether the draw was done as a preview (for the editor).
+- **Drawing:** The [Drawing](https://github.com/SpoinkyNL/Artemis/wiki/Drawing) object for this frame. Use this to draw your own shapes.
+ 
+#### Example
+```lua
+-- This function will be called after every profile draw.
+function drawHandler(profile, eventArgs)
+	-- Put your code here
+end
+
+-- Subscribe to the event AFTER defining the function which must be subscribed.
+Events.ProfileDrawing.add(drawHandler);
+```
