-## Format/Style Java Code
+## Further Contribution Guidance
 
-The Java code is formatted according to Google Java Style (AOSP variant). The build automatically checks
-that the code conforms to the style (using [Spotless], which delegates to [google-java-format]), it can
-also be used to format the code (with the Gradle task `spotlessJavaApply`) if the IDE/editor in use
-does not support it.
