+Configuration Overview
+======================
+
+While Jupyter Notebook installs with default configuration settings, Jupyter
+Notebook provides a rich array of options that may be configured to suit
+your workflow. Let's explore four areas of configuration:
+
+- Jupyter's Common Configuration system
+- Notebook server
+- Notebook front-end client
+- Notebook extensions
+
+
+:ref:`Security in Jupyter notebooks <notebook_security>` is a topic worthy of
+serious consideration. Since security policies will vary from organization to
+organization, we encourage you to consult with your security team on settings
+that would be best for your use cases. Our documentation offers some
+responsible security practices, and we recommend that you become familiar
+with the practices.
