+```
+

+Add to `TreeWalker` module:
+
+```xml
+<module name="com.smlnskgmail.jaman.checkstyle.checks.UtilityClassPrivateConstructorCheck">
+    <property name="id" value="UtilityClassPrivateConstructorCheck" />
+</module>
+```
+
+## How to contribute
+
+Read [Commit Convention](https://github.com/fartem/repository-rules/blob/master/commit-convention/COMMIT_CONVENTION.md). Make sure your build is green before you contribute your pull request. Then:
