-Tuning Box - configuration storage for your clouds
+Tuning Box is a configuration storage for your clouds.
 
-Please feel here a long description which must be at least 3 lines wrapped on
-80 cols, so that distribution package maintainers can use it in their packages.
-Note that this is a hard requirement.
+Tuning Box can be used as a centralized storage for all configurations. It
+supports Keystone authentication. By default, Tuning Box installs as a Fuel
+extension but also it can be run as a service.

+------------
+
+#. Download Tuning Box RPM package or code to the Fuel Master node. The
+   package can be built from the source code using::
+
+    $ python setup.py bdist_rpm
+
+#. Tuning Box installs as a Fuel Nailgun extension. Therefore, perform the
+   DB migration and restart the Nailgun service::
+
+    $ nailgun_syncdb
+    $ systemctl restart nailgun.service
+
+#. Configure the Tuning Box keystone service::
+
+    $ export OS_USERNAME=admin OS_PASSWORD=admin OS_PROJECT_NAME=admin OS_AUTH_URL=http://10.20.0.2:5000
+    $ openstack service create --name tuning-box config
+    $ openstack endpoint create --publicurl http://10.20.0.2:8000/api/config --region RegionOne tuning-box
