+== Getting the right version
+
+The tooling can be made available in two different versions: `release` and `milestone`. The release version represents a stable version of the product
+and can be referenced in your projects in the usual way from the Maven Central repository. There is also the possibility to have the intermediate builds
+made available, these are called `milestone` builds. Instead of Maven Central, these are released via 
+https://github.com/orgs/OpenManufacturingPlatform/packages?repo_name=sds-sdk[GitHub Packages] mechanism. +
+To be able to use the artifacts released in this way in your projects, first the right repository has to be added to your `pom.xml` file:
+[source, xml]
+----
+<repositories>
+  <repository>
+	 <id>github</id>
+	 <name>OpenManufacturingPlatform SDS-SDK</name>
+	 <url>https://maven.pkg.github.com/OpenManufacturingPlatform/sds-sdk</url>
+	 <releases><enabled>true</enabled></releases>
+	 <snapshots><enabled>true</enabled></snapshots>
+  </repository>
+</repositories>
+----
+Then the desired dependencies can be referenced in the usual way. For an example, please refer to 
+https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-apache-maven-registry#installing-a-package[Github - Installing a package].
