 ====================
 To build a specific module, run the command: `mvn clean install` in the module directory.
 
+It can happen that your module is part of a parent module e.g. `parent-boot-1`,`parent-spring-5` etc, then you will need to build the parent module first so that you can build your module.
+We have created a `parents` profile that you can use to build just the parent modules, just run the profile as:
+`mvn clean install -Pparents`
+
