+Introduction
+============
+
+ucloud is a modern, IPv6 first virtual machine management system.
+It is an alternative to `OpenNebula <https://opennebula.org/>`_,
+`OpenStack <https://www.openstack.org/>`_ or
+`Cloudstack <https://cloudstack.apache.org/>`_.
+
+ucloud is the first cloud management system that puts IPv6
+first. ucloud also has an integral ordering process that we missed in
+existing solutions.
+
+The ucloud documentation is separated into various sections for the
+different use cases:
+
+* :ref:`The user guide <user-guide>` describes how to use an existing
+  ucloud installation
+* There are :ref:`setup instructions <setup-install>` which describe on how to setup a new
+  ucloud instance
+* :ref:`The admin guide <admin-guide>` describe on how to
+  administrate ucloud
