+# Module kotlin-reflect
+
+## Kotlin JVM reflection extensions
+
+The library provides the runtime component that enables full support of the reflection features in `kotlin.reflect` package 
+and extensions for the reflection types.
+
+It's provided as an optional artifact separate from the standard library to reduce the required size of the runtime dependencies
+for applications that do not use reflection features. 
+
+# Package kotlin.reflect.full
+
+Extensions for [Kotlin reflection](https://kotlinlang.org/docs/reference/reflection.html) types like [kotlin.reflect.KClass], [kotlin.reflect.KType], and others.
+
+# Package kotlin.reflect.jvm
+
+Extensions for conversion between [Kotlin reflection](https://kotlinlang.org/docs/reference/reflection.html) and
+Java reflection types and other JVM-specific extensions.
