+Preparing configuration/description files
+-----------------------------------------
+
+Put OpenStack RC file (admin_rc.sh), os_carcert and pod.yaml (pod descrition file) in /tmp directory.
+Edit admin_rc.sh and add the following line
+
+.. code-block:: bash
+
+ export OS_CACERT=/tmp/os_cacert
+
+If you are using compass, fuel, apex or joid to deploy your openstack
+environment, you could use the following command to get the required files.
+
+.. code-block:: bash
+
+ bash /utils/env_prepare/config_prepare.sh -i <installer> [--debug]
+
+Note that if we execute the command above, then admin_rc.sh and pod.yml gets created automatically in /tmp folder along with the line `export OS_CACERT=/tmp/os_cacert` added in admin_rc.sh file.
