 ## General use
 
-### `JmhCleaner` rule
+### `JmhCleaner` extension
 
 JMH is kinda dirty. It leaves after himself a set of tests classes. They are placed in Maven generated sources directory and may cause a false positives in code analysis tools like SonarQube. `JmhCleaner` rule is designed to overcome that and remove any JMH generated classes.
 
-Use it as a standard JUnit test rule or class rule. One needs to pass a test class in constructor.
+Use it as a standard JUnit 5 extension. One needs to pass a test class in constructor.
 
 Example:
 
 ```java
-@ClassRule
-public static JmhCleaner cleaner = new JmhCleaner(MyClassTest.class);
+@RegisterExtension
+static JmhCleaner cleaner = new JmhCleaner(MyClassTest.class);
 ```
 
-### `JavaAgentSkip` rule
+### `JavaAgentSkip` extension
 
-JMH is, as any performance framework, sensitive to all intrussions like running java agents. Those are coverage tools (Jacoco), debuggers, profilers and so on. To overcome that one can use `JavaAgentSkip` rule to automatically skip test is JAva agent is present.

-### All in one
-
-If you like to use both those rules, it's a good idea to place them in explicit order, to ensure cleaning is performed.
-
-```java
-@ClassRule
-public static RuleChain chain = RuleChain
-    .outerRule(new JmhCleaner(ExhibitFactoryIT.class))
-    .around(JavaAgentSkip.ifPresent());
+@RegisterExtension
+static JavaAgentSkip javaAgentSkip = JavaAgentSkip.ifPresent();
 ```
