-command-line tools installingas root:
+.. note::
 
-.. code-block:: console
-
-   # pip install [--upgrade] <package-name>
-
-To remove the package:
-
-.. code-block:: console
-
-   # pip uninstall <package-name>
-
-If you need even newer versions of the clients, pip can install directly
-from the upstream git repository using the :option:`-e` flag. You must specify
-a name for the Python egg that is installed. For example:
-
-.. code-block:: console
-
-   # pip install -e git+https://git.openstack.org/openstack/python-novaclient#egg=python-novaclient

-If you support the EC2 API on your cloud, you should also install the
-euca2ools package or some other EC2 API tool so that you can get the
-same view your users have. Using EC2 API-based tools is mostly out of
-the scope of this guide, though we discuss getting credentials for use
-with it.
