-## Maven Checkstyle Plugin
+## Checkstyle
 
-The [Maven Checkstyle Plugin](https://maven.apache.org/plugins/maven-checkstyle-plugin/)
-uses the latest version of the Checkstyle library
-([Release Notes](http://checkstyle.sourceforge.net/releasenotes.html)) and the
-[Sevntu](http://sevntu-checkstyle.github.io/sevntu.checkstyle/) library.
+The Checkstyle plugin is configured using the
+`kemitix-checkstyle-ruleset-maven-plugin`.
 
-As from version 2.0.0 you no longer provide a `checkstyle.xml` file. Any file you
-provide will be ignored unless you re-configure the maven-checkstyle-plugin yourself.
-
-The ruleset that will be used is defined in
-[kemitix-checkstyle-ruleset](https://github.com/kemitix/kemitix-checkstyle-ruleset).
-See that project's `README.md` file for details on the ruleset.
+The `kemitix-checkstyle-ruleset` provides five levels of checks. The
+default is set to `5-complexity`, the most strict.
 
 ### Configuration
 
-Ref [checkstyle:check](https://maven.apache.org/plugins/maven-checkstyle-plugin/check-mojo.html)
+Set the property `kemitix-checkstyle-ruleset.level` to one of the
+following values to select a less-strict ruleset:
 
-* configLocation: [checkstyle.xml](https://github.com/kemitix/kemitix-checkstyle-ruleset/blob/master/src/main/resources/net/kemitix/checkstyle.xml)
-* consoleOutput: true
-* encoding: UTF-8
-* failOnViolation: true
-* failOnError: true
-* linkXRef: true
+* 1-layout
