+Fill to Gradient node
+~~~~~~~~~~~~~~~~~~~~~
+
+The **Fill to Gradient** node uses the output of the **Fill** node and fills
+all detected areas with one or multiple layers of gradients.

+
+Inputs
+++++++
+
+The **Fill to Gradient** node accepts the output of a **Fill** node (or a
+compatible output of another node) as input.
+
+Outputs
++++++++
+
+The **Fill to Gradient** node outputs the generated gradient.
+
+Parameters
+++++++++++
+
+The **Fill to Gradient** node accepts the following parameters:
+
+* The *Gradient*
+
+* The *Mode* defines how the gradient is spread out on each area (strectch or square).
+
+* *Layers* defines how many layers of the gradient will be applied to each fill area, blended with the min function (darken).
+
+* *Rotate* defines the base rotation of the gradient.
+
+* *Random Rotation* defines how much the rotation should be randomized for each gradient.
+
+* *Random Offset* defines how much each gradient get's randomly offset.
