+  Configure Jenkins to poll changes in SCM.--
+
+  <p>
+  Note that this is going to be an expensive operation for CVS, as every polling
+  requires Jenkins to scan the entire workspace and verify it with the server.
+  Consider setting up a "push" trigger to avoid this overhead, as described in
+  <a href="https://jenkins.io/redirect/scm-change-trigger">this document</a>
