+## What will we build?
+This is might not be a spectacutlar use case for Transistion, but it should give an idea, how to use Transistion.
+This is example consist of a **Text** which will print the active value of the Transition state and a padding which will change depending on this state.
+The value of the Transistion state will change from 0 to 200 over and over again.
+
+## Create a transistion definition
+Transistion requires a TransitionDefinition, so let's build that first.
+
+```kotlin
+private val paddingTransitionDefinition = transitionDefinition {
+...
+}
+```
+
+Inside the TransitionDefinition, we have to define all possible transition states and which transition should be used between two transition states.
+In this example we want to create transition between 0 and 200, so let's create two states for that.
+
+```kotlin
+private val paddingPropKey = FloatPropKey()
+
+private val paddingTransitionDefinition = transitionDefinition {
+ state("A"){ this[paddingPropKey] = 0f }
+ state("B") { this[paddingPropKey] = 200f }
+...
+}
+```  
+
+Inside **transitionDefinition** you have to use the **state()** to define a transition state. It requires a name and a function to initialize a state.
+**paddingPropKey** is a **FloatPropKey**, it's like a state with a float value. It will be constantly updated with the latest value inside the transition.
+
+Now we have two states. One with the Name **A** and a paddingPropKey value of **0f** and one with the Name **B** and a paddingPropKey value of **200f**. Next we have to define a transistion between **A** and **B**.
+
+```kotlin
+private val paddingPropKey = FloatPropKey()
+
+private val paddingTransitionDefinition = transitionDefinition {
+ state("A"){ this[paddingPropKey] = 0f }
+ state("B") { this[paddingPropKey] = 200f }
+
+ transition("A" to "B") {
+        paddingPropKey using repeatable {
+            animation = tween {
+                duration = 1000
+                easing = FastOutLinearInEasing
+            }
+            iterations = Infinite
+        }
+    }
+}
+
+```
+
+With
+```kotlin
+ transition("A" to "B")
+```
+a transistion between state **A** and state **B** is definied. Inside the transition you have to define **how**, **how long** and **how often** the transition should happen.
