+### This Sample is created for this blog
+https://medium.com/@Tarek360/annotation-processor-to-avoid-boilerplate-af0b8820297d
+
+This Android project sample demonstrates how to generate a class by an [annotation processor](/processor/src/main/java/com/tarek360/EasyJSONProcessor.kt) written in Kotlin.
+
+The generated code is in Java but the [annotation processor](/processor/src/main/java/com/tarek360/EasyJSONProcessor.kt) written in Kotlin.
