 Code Style
 ==========
 
-Code style is enforced with Checkstyle. The configuration is located at `checkstyle`_.
-You can also just check the style without building the project.
-This checks the code style of all source code under the current directory or from within an individual module.
+The current Java code styles are configured as follows:
+- Indent: Tabs & spaces (2 spaces per tab)
+- Google Java Format: Reformats Java source code to comply with `Google Java Style`_.
+- Configure license headers for Java & XML files
+
+Java code style is checked by `Spotless`_ during the build, and the continuous integration build will verify
+that changes adhere to the style guide.

+Automatically fixing code style issues
+--------------------------------------

+- You can also just check the style without building the project with `mvn spotless:check`.
+- The Java code style can be corrected from the command line by using the following commands: `mvn spotless:apply`.
