 ### Build
 Build and run Unit Tests:
 
-    ./gradlew build
-
+```shell
+./gradlew build
+```
+`
 ## Integration Tests
 
 By default, Integration Tests (ITs) are skipped during builds.
 If you want to run them, you need first to retrieve the related projects which are used as input:
 
-    git submodule update --init its/sources
+```shell
+git submodule update --init
+```
 
 Then build and run the Integration Tests using the `its` property:
 
+```shell
     ./gradlew build -Pits --info --no-daemon
+```
 
 You can also build and run only Ruling Tests using the `ruling` property:
 
-    ./gradlew build -Pruling --info --no-daemon
+```shell
+./gradlew build -Pruling --info --no-daemon
+```
 
 ## License headers
 
 License headers are automatically updated by the spotless plugin but only for Java files. 
 Furthermore, there are files such as `package-info.java` and `module-info.java` that spotless ignores. 
 Also the Go source files are not handled. For those files use a manual script like below to update the license:
-    `find . -type f -name "*.go" -exec sed -i '' 's/2018-2023/2018-2024/' "{}" \;`
+
+```shell
+`find . -type f -name "*.go" -exec sed -i '' 's/2018-2023/2018-2024/' "{}" \;`
+```
