 # test-naming-conventions
 
+Almost each project uses unit tests in codebase. It is important to have 
+a common pattern of naming all that tests, because otherwise the project and
+tests itself become a complete mess. It's a quite large discussion about
+different [test naming patterns](https://stackoverflow.com/questions/155436/unit-test-naming-best-practices).
+**test-naming-conventions** maven plugin helps to keep follow a single 
+common test naming rule across all of your test classes.
+## How to use
+In order to use the plugin with the latest version just invoke the next 
+command in the root of your project: 
 ```shell
 mvn com.github.volodya-lombrozo:test-naming-conventions:check
+```
+If you want to use specific version, for example `0.1.0`, just run the next
+command
+```shell
+mvn com.github.volodya-lombrozo:test-naming-conventions:0.1.0:check
 ```
