+CUE.NET defines a gradient as a line on which each point represents a specific color.  
+Usually this color is calculated from either a set of _GradientStops_ or any other function.  
+
+Please note that a gradient does **not** define any shape or something similar. It's just calculating a color for the specified offset on itself.  
+A gradient itself is therefore barely useful. That's where [brushes](https://github.com/DarthAffe/CUE.NET/wiki/Understanding-CUE.NET-brushes) come into play.
+Most of them get there color values provided by a gradient.
+
+CUE.NET provides by default two gradients:
+* [Linear-Gradient](https://github.com/DarthAffe/CUE.NET/wiki/Linear-Gradient)
+* [Rainbow-Gradient](https://github.com/DarthAffe/CUE.NET/wiki/Rainbow-Gradient)
+
+Of course you can always [implement your own gradient](https://github.com/DarthAffe/CUE.NET/wiki/Implementing-an-own-gradient).
