+  Deterministic GIF recording for Jetpack Compose scenarios using a Gradle plugin
 </p>
 
+## Motivation
+
+This plugin was originally created to automate GIF generation
+for the Compose [Charts wiki documentation](https://charts.harisdautovic.com/2.2.0/wiki/examples).
+
+Whenever chart styles, animations, or APIs change,
+all documentation GIFs can be easily regenerated in an automated way.
+
 ## Requirements
 
 - Android app module using Jetpack Compose
