+
+## Running Tests
+
+The new code should contain tests that check new behavior.
+
+Run tests `./gradlew test` to check that code works as behavior.
+
+## Code Style
+
+The code base should remain clean, following industry best practices for organization, javadoc and style, as much as possible.
+
+To run the Code Style check use `./gradlew spotlessCheck`.
+
+If check found any errors, you can apply Code Style by running `./gradlew spotlessApply`
