+tripleo_overcloud_node_delete
+========================
+
+A role to run node delete.
+
+Requirements
+------------
+
+None.
+
+Role Variables
+--------------
+
+* `tripleo_overcloud_node_delete_nodes`: Node ID(s) to delete (otherwise specified in the --baremetal-deployment file)
+* `tripleo_overcloud_node_delete_baremetal_deployment`: Configuration file describing the baremetal deployment
+* `tripleo_overcloud_node_delete_stack`: Name or ID of heat stack to scale (default=Env: OVERCLOUD_STACK_NAME)
+* `tripleo_overcloud_node_delete_templates`: The directory containing the Heat templates to deploy.
+    This argument is deprecated. The command now utilizes a deployment plan, which should be updated prior to running this
+    command, should that be required. Otherwise this argument will be silently ignored.
+* `tripleo_overcloud_node_delete_environment_file`: Environment files to be passed to the heat stack-create or heat stack-update command.
+    (Can be specified more than  once.) This argument is deprecated. The command now utilizes a deployment plan,
+    which should be updated prior to running this command, should that be required. Otherwise this argument will be silently ignored.
+* `tripleo_overcloud_node_delete_timeout`: Timeout in minutes to wait for the nodes to be deleted.
+    Keep in mind that due to keystone session duration that timeout has an upper bound of 4 hours
+* `tripleo_overcloud_node_delete_yes`: Skip yes/no prompt (assume yes)
+* `tripleo_overcloud_node_delete_os_cloud`: (String) OS_CLOUD value to use when running the command. If `tripleo_os_cloud` is defined, it will be the default. Otherwise the default is ''. This variable takes precedence over `tripleo_overcloud_node_delete_rc_file`.
+* `tripleo_overcloud_node_delete_rc_file`: (String) Path to the credential file to use. If `tripleo_rc_file` is defined, it will be the default. Default: "{{ ansible_env.HOME }}/stackrc"
+
+NOTE: Please note that this command should be run against the undercloud so the
+OS_CLOUD or rc file variables should be set to use the 'undercloud' when
+calling this role. If you are not defining `tripleo_os_cloud` or `tripleo_rc_file`,
+stackrc will be used by default.
+
+Output Variables
+----------------
+
+* `tripleo_overcloud_node_delete_output`: (String) The command standard output.
+* `tripleo_overcloud_node_delete_result`: Ansible shell execution results
+
+Dependencies
+------------
+
+None.
+
