+Additions allow you to add arbitrary C# to the generated classes
+before they are compiled.  This can be helpful for providing convenience
+methods or adding pure C# classes.
+
+== Adding Methods to Generated Classes ==
+
+Let's say the library being bound has a Rectangle class with a constructor
+that takes an x and y position, and a width and length size.  It will look like
+this:
+
+public partial class Rectangle
+{
+    public Rectangle (int x, int y, int width, int height)
+    {
+        // JNI bindings
+    }
+}
+
+Imagine we want to add a constructor to this class that takes a Point and
+Size structure instead of 4 ints.  We can add a new file called Rectangle.cs
+with a partial class containing our new method:
+
+public partial class Rectangle
+{
+    public Rectangle (Point location, Size size) :
+        this (location.X, location.Y, size.Width, size.Height)
+    {
+    }
+}
+
+At compile time, the additions class will be added to the generated class
+and the final assembly will a Rectangle class with both constructors.
+
+
+== Adding C# Classes ==
+
+Another thing that can be done is adding fully C# managed classes to the
+generated library.  In the above example, let's assume that there isn't a
+Point class available in Java or our library.  The one we create doesn't need
+to interact with Java, so we'll create it like a normal class in C#.
+
+By adding a Point.cs file with this class, it will end up in the binding library:
+
+public class Point
+{
+    public int X { get; set; }
+    public int Y { get; set; }
+}
