+Install pip through deployment host
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You may install pip via the deployment host in environments where the
+deployment host has internet connectivity, but the containers do not.
+
+Configure the ``pip_offline_install`` variable to enable the deployment
+host to fetch pip along with its dependencies, then transfer them to the
+remote container for installation.
+
+Configuration changes are made in ``/etc/openstack_deploy/user_variables.yml``.
