+
+#### [Optional reading] Release train build details
+
+The release train build does two very important steps as the first things,
+i.e. build the external dependency P2 repositories for both the
+Platform SDK and Simupedia:
+~~~
+stage('External Dependencies') {
+    node {
+        build job: 'SDK/Deploy External Components to Web', parameters: params1
+        build job: 'Member Components/Simupedia/fi.semantum.simupedia.build.p2.site', parameters: params1
+    }    
+}
+~~~
+After that it builds the Platform SDK and Simupedia before building anything else:
+~~~
+stage('SDK') {
+    node {
+        build job: 'SDK/Simantics SDK', parameters: params1
+        // Note that Simantics SDK builds simupedia-git as well
+    }
