+``INSTALLER_TYPE`` should be one of OPNFV installer, e.g. apex, compass, daisy, fuel
+and joid. Currenty, QTIP only supports installer fuel.

+Getting start with compute QPI
+------------------------------
+
+Notice: All descriptions are based on QTIP container.
+
+Inventory File
+^^^^^^^^^^^^^^
+
+QTIP uses Ansible to trigger benchmark test. Ansible uses an inventory file to
+determine what hosts to work against. QTIP can automatically generate a inventory
+file via OPNFV installer. Users also can write their own inventory infomation into
+``/home/opnfv/qtip/hosts``. This file is just a text file containing a list of host
+IP addresses. For example:
+::
+
+ [hosts]
+ 10.20.0.11
+ 10.20.0.12
+
+QTIP key Pair
+^^^^^^^^^^^^^
+
+QTIP use a SSH key pair to connect to remote hosts. When users execute compute QPI,
+QTIP will generate a key pair named *QtipKey* under ``/home/opnfv/qtip/`` and pass
+public key to remote hosts.
+
+If environment variable *CI_DEBUG* is set to *true*, users should delete it by
+manual. If *CI_DEBUG* is not set or set to *false*, QTIP will delete the key from
+remote hosts before the execution ends. Please make sure the key deleted from remote
+hosts or it can introduce a security flaw.
+
+Commands to run compute QPI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In a QTIP container, you can run compute QPI by using QTIP CLI:
+::
+
+ mkdir result
+ qtip plan run <plan_name> -p $PWD/result
+
+QTIP generates results in the ``$PWD/result`` directory are listed down under the
+timestamp name.
+
+you can get more details from *userguide/cli.rst*.
