 Then you may add your sprites or other objects to the grid by calling `Add(object, Point/Vector2/Rectangle/Rect)` or `Move(object, Point/Vector2/Rectangle/Rect)`. Move removes the item first if it was present on the grid.  
 
 ### Parameters
-The first parameter is your item. The grid is generic and there are no constraints for that.  
-The second parameter is always one of the following:
-| Parameter | Description | Info |
-|:----------|:------------|:-----|
-|Point|This is an int-point.|By specifying this you tell the grid you mean the cell at exactly this position.|
-|Vector2|This is a float-vector.|By specifying this you tell the grid that you mean the cell that contains these game-coordinates.|
-|Rectangle|This is a basic int-rectangle. It is not rotated and therefore axis-alinged. So it's an Axis-Aligned-Bounding-Box or AABB.|By specifying this you give the grid a rectangle in the cell-coordinate-system (0-numberOfCellsX, 0-numberOfCellsY).|
-|Rect|This is a special parameter in our utility-package. It's essentially a Rectangle, but with all float parameters.|By specifying this you give the grid a rectangle in the game-coordinate-system.|

+    By specifying this you give the grid a rectangle in the game-coordinate-system.  
+  
 All rectangles this grid works with are axis-aligned.  
 
 You're free to remove them at any time by using one of the remove-methods `Remove(Point/Vector2/Rectangle/Rect)`.
 
 The method `Get(Point/Vector2/Rectangle/Rect)` returns an array of your items with all of them that the grid has encountered in the area you've specified when calling `Get`. If it doesn't find any it returns an empty array.
 
+If you add your sprites by their position, then this is what the grid will basically do:  
 ![Position Test][testposition]
 
+If you add your sprites by their AABBs, then this is what the grid will basically do:  
 ![Rectangle Test][testrectangle]
