 ## Coding Style Guidelines
+Our code base is formatted according to the [Google Java Style Guide](https://google.github.io/styleguide/javaguide.html).

+The project is configured to use the [google-java-format-gradle-plugin](https://github.com/sherter/google-java-format-gradle-plugin) which can be utilized as follows:  
+
+* Execute the task `googleJavaFormat` to format all `*.java` files in the project:
+
+`./gradlew goJF`
+
+* Execute the task `verifyGoogleJavaFormat` to verify that all `*.java` files are formatted properly:
+
+`./gradlew verGJF`
