 Use-Case View
 =============
-TBD(kubi)
+Yardstick Use-Case View shows two kinds of users. One is the Tester who will
+do testing in cloud, the other is the User who is more concerned with test result
+and result analyses.
+
+For testers, they will run a single test case or test case suite to verify
+infrastructure compliance or bencnmark their own infrastructure performance.
+Test result will be stored by dispatcher module, three kinds of store method
+(file, influxdb and http) can be configured. The detail information of
+scenarios and runners can be queried with CLI by testers.
+
+For users, they would check test result with four ways.
+
+If dispatcher module is configured as file(default), there are two ways to
+check test result. One is to get result from yardstick.out ( default path:
+/tmp/yardstick.out), the other is to get plot of test result, it will be shown
+if users execute command "yardstick-plot".
+
+If dispatcher module is configured as influxdb, users will check test
+result on Grafana which is most commonly used for visualizing time series data.
+
+If dispatcher module is configured as http, users will check test result
+on OPNFV testing dashboard which use MongoDB as backend.
