+
+Expose variables to [Chataigne](http://benjamin.kuperberg.fr/chataigne/en) and any other applications that can interface with it.
+The current implementation makes use of the OSC protocol and supports `Double` and `ColorRGBa`.
+
+## Usage
+
+Defining the variables
+```kotlin
+class SceneVariables : ChataigneOSC(OSC(portIn = 9005, portOut = 12001)) {
+        val myRadius: Double by DoubleChannel("/myRadius")
+        val myOpacity: Double by DoubleChannel("/myOpacity")
+        val myColor: ColorRGBa by ColorChannel("/myColor")
+}
+```
+
+Initiate
+
+```kotlin
+ val animation = SceneVariables()
+```
+
+Update time
+
+```kotlin
+animation.update(seconds)
+```
+
+Use the variables
+
+```kotlin
+animation.myRadius
+animation.myOpacity
+animation.myColor
+```
+
+## Example project
+
+Find the Chataigne example project in `/resources/timeline_example_chataigne.noisette` which works together with demo project `/src/demo/kotlin/ChataigneOSCDemo.kt`
