+${project.name}
+
+    This POM is the common parent of all of the {{{/extensions/}Maven extensions}}
+    in the Apache Maven project.
+
+* The <<<run-its>>> Profile
+
+    This POM provides <<<run-its>>> profile for running Integration Tests to check real extension execution.
+    A default configuration for <<<maven-invoker-plugin>>> is defined, that every extension needs to enhance
+    to match its prerequisite. Then ITs are launched in every extension with following command:
+
++---+
+mvn -Prun-its verify
++---+
+
+
+* Site Publication
+
+    Since Maven extensions are always mono-module builds, this parent POM has configured <<<maven-scm-publish-plugin>>>
+    {{{/plugins/maven-scm-publish-plugin/examples/one-module-configuration.html}mono module optimization}}
+    to ease site build & deployment in only one integrated and simplified command:
+
++-----+
+mvn -Preporting site-deploy
++-----+
+
+* History
