 definition [here](https://github.com/AxonFramework/AxonFramework/blob/master/axon_code_style.xml). Simply import the XML
 file in under "Settings -> Code Style -> Scheme -> Import Scheme". Doing so should make the code style selectable
 immediately.
+
+### Project Build
+
+The project is built with Apache Maven, supplied by the Maven Wrapper `mvnw`. For separate aspects of the build Maven 
+profiles are used.
+
+For a **regular** build, execute from your command line: `./mvnw`. This will run the build and execute JUnit tests
+of all modules and package the resulting artifacts. 
+
+There is an example project supplied, and you can skip its build by passing `-DskipExamples` to your build command. 
+
+The long-running integration tests (starting Spring Boot Application and/or running Kafka in a TestContainer) are 
+provided and **ARE NOT** executed by default. A special **itest** build is needed to run those long-running tests. 
+If you want to run them, please call `./mvnw -Pitest` from your command line. If you need to provide additional 
+integration tests, make sure the class name ends with `IntegrationTest`.
+
+The project uses JaCoCo to measure test coverage of the code and will automatically generate coverage reports on regular
+and itest build. If you are interested in the overall test coverage, please run `./mvnw -Pcoverage-aggregate` 
+(without calling `clean`) after your run the **regular** and **itest** builds and check the resulting aggregated report 
+in `./coverage-report-generator/target/site/jacoco-aggregate/index.html`
+
