+    Horizon Plugin for Container Management service is
+    released as Zun UI. Zun UI work with Horizon, and
+    service user interfaces for container management to
+    users. For example, Zun UI provides table views and
+    details view for container, these views have twelve
+    operations for container. Also, this has
+    WebSocket-based console view. Zun UI is implemented
+    Angular-based, and supports latest features in Horizon.
+features:
+  - >
+    [`blueprint add-container-operations <https://blueprints.launchpad.net/zun-ui/+spec/add-container-operations>`_]
+    Operations for container, such as 'Start', 'Stop',
+    'Restart', 'Pause', 'Unpause', 'Execute Command' and
+    'Send Kill Signal', are added. Also, while loading
+    details view, then logs of container are shown in
+    'Logs' tab.

+    UI gets the URL for container "tty" from docker and
+    accesses the "tty" via WebSocket to realize console on
+    the browser.
