-### API Diff
-
-This plugin uses the [Gradle JApiCmp](https://github.com/melix/japicmp-gradle-plugin) plugin
-to generate API Diff reports for each Spring Framework module. This plugin is applied once on the root
-project and creates tasks in each framework module. Unlike previous versions of this part of the build,
-there is no need for checking out a specific tag. The plugin will fetch the JARs we want to compare the
-current working version with. You can generate the reports for all modules or a single module:
-
-```
-./gradlew apiDiff -PbaselineVersion=5.1.0.RELEASE
-./gradlew :spring-core:apiDiff -PbaselineVersion=5.1.0.RELEASE
-```

-The reports are located under `build/reports/api-diff/$OLDVERSION_to_$NEWVERSION/`.

+
+Dealing with generic types in Spring applications written in Kotlin may require, for some use cases, to understand
+Kotlin https://kotlinlang.org/docs/generics.html#declaration-site-variance[declaration-site variance]
+which allows to define the variance when declaring a type, which is not possible in Java which supports only use-site
+variance.
+
+For example, declaring `List<Foo>` in Kotlin is conceptually equivalent to `java.util.List<? extends Foo>` because
+`kotlin.collections.List` is declared as
+https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/[`interface List<out E> : kotlin.collections.Collection<E>`].
+
+This needs to be taken in account by using the `out` Kotlin keyword on generic types when using Java classes,
+for example when writing a `org.springframework.core.convert.converter.Converter` from a Kotlin type to a Java type.
