+Without InfluxDB, Yardstick stores results for runnning test case in the file
+``/tmp/yardstick.out``. However, it's unconvenient to retrieve and display
+test results. So we will show how to use InfluxDB to store data and use
+Grafana to display data in the following sections.
 
-Create InfluxDB container and config with the following command::
+Automatically deploy InfluxDB and Grafana containers (**recommended**)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-  yardstick env influxdb
+Firstly, enter the Yardstick container::
 
+  docker exec -it yardstick /bin/bash
 
-Create Grafana container and config::
+Secondly, create InfluxDB container and configure with the following command::
 
-  yardstick env grafana
+  yardstick env influxdb
+
+Thirdly, create and configure Grafana container::
 
-Then you can run a test case and visit http://host_ip:3000(user:admin,passwd:admin) to see the results.
+  yardstick env grafana
 
-note: Using **yardstick env** command to deploy InfluxDB and Grafana requires
-Jump Server's docker API version => 1.24. You can use the following command to
-check the docker API version:
+Then you can run a test case and visit http://host_ip:3000 (``admin``/``admin``) to see the results.
 
-::
+**NOTE:** Executing ``yardstick env`` command to deploy InfluxDB and Grafana requires Jumphost's docker API version => 1.24. Run the following command to check the docker API version on the Jumphost::
