+## Noise function composition
+
+Since ORX 0.4 the orx-noise module comes with functional composition tooling that allow one to create complex noise
+functions.
+
+```kotlin
+// create an FBM version of 1D linear perlin noise
+val myNoise0 = perlinLinear1D.fbm(octaves=3)
+val noiseValue0 = myNoise0(431, seconds)
+
+// create polar version of 2D simplex noise
+val myNoise1 = simplex2D.withPolarInput()
+val noiseValue1 = myNoise1(5509, Polar(seconds*60.0, 0.5))
+
+// create value linear noise with squared outputs which is then billowed
+val myNoise2 = valueLinear1D.mapOutput { it * it }.billow()
+val noiseValue2 = myNoise2(993, seconds * 0.1)
+```

 ## Multi-dimensional noise
 
 These are a mostly straight port from FastNoise-Java but have a slightly different interface.
