+
+Legend:
+
+✅ Deployed to Maven Central: Public API modules that external users can depend on
+
+❌ Not Deployed: Internal infrastructure, test utilities, and build configuration
+
+### Why Two Parent POMs?
+
+As you can see in the table above, not all modules are intended to be deployed on Maven Central. The distinction is made by using two parent POMs. 
+
+The base POM is `openfasttrace-parent`, it mainly contains common dependencies and build configuration. On top of that, `openfasttrace-mc-deployable-parent` adds signing and Maven central deployment. 
+
+This structure ensures that only user-facing components are published to Maven Central while keeping internal development tools and build infrastructure private.
