+Installing a plug-in into yardstick
+===================================
+
+Abstract
+========
+
+Yardstick currently provides a ``plugin`` CLI command to support integration
+with other OPNFV testing projects. Below is an example invocation of yardstick
+plugin command and Storperf plug-in sample.
+
+
+Installing Storperf into yardstick
+==================================
+
+Storperf is delivered as a Docker container from
+https://hub.docker.com/r/opnfv/storperf/tags/.
+
+There are two possible methods for installation in your environment:
+
+* Run container on Jump Host
+* Run container in a VM
+
+In this introduction we will install Storperf on Jump Host.
+
+
+Step 0: Environment preparation
+>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
+
+Running Storperf on Jump Host
+Requirements:
+
+* Docker must be installed
+* Jump Host must have access to the OpenStack Controller API
+* Jump Host must have internet connectivity for downloading docker image
+* Enough floating IPs must be available to match your agent count
+
+Before installing Storperf into yardstick you need to check your openstack
+environment and other dependencies:
+
+1. Make sure docker is installed.
+2. Make sure Keystone, Nova, Neutron, Glance, Heat are installed correctly.
+3. Make sure Jump Host have access to the OpenStack Controller API.
+4. Make sure Jump Host must have internet connectivity for downloading docker image.
+5. You need to know where to get basic openstack Keystone authorization info, such as
+   OS_PASSWORD, OS_TENANT_NAME, OS_AUTH_URL, OS_USERNAME.
+6. To run a Storperf container, you need to have OpenStack Controller environment
+   variables defined and passed to Storperf container. The best way to do this is to
+   put environment variables in a "storperf_admin-rc" file. The storperf_admin-rc
+   should include credential environment variables at least:
+
+* OS_AUTH_URL
+* OS_TENANT_ID
+* OS_TENANT_NAME
+* OS_PROJECT_NAME
+* OS_USERNAME
+* OS_PASSWORD
+* OS_REGION_NAME
+
+For this storperf_admin-rc file, during environment preparation a "prepare_storperf_admin-rc.sh"
+script can be used to generate it.
+::
+
+  #!/bin/bash
+  AUTH_URL=${OS_AUTH_URL}
+  USERNAME=${OS_USERNAME:-admin}
+  PASSWORD=${OS_PASSWORD:-console}
+  TENANT_NAME=${OS_TENANT_NAME:-admin}
+  VOLUME_API_VERSION=${OS_VOLUME_API_VERSION:-2}
+  PROJECT_NAME=${OS_PROJECT_NAME:-$TENANT_NAME}
+  TENANT_ID=`keystone tenant-get admin|grep 'id'|awk -F '|' '{print $3}'|sed -e 's/^[[:space:]]*//'`
+  rm -f ~/storperf_admin-rc
+  touch ~/storperf_admin-rc
+  echo "OS_AUTH_URL="$AUTH_URL >> ~/storperf_admin-rc
+  echo "OS_USERNAME="$USERNAME >> ~/storperf_admin-rc
+  echo "OS_PASSWORD="$PASSWORD >> ~/storperf_admin-rc
+  echo "OS_TENANT_NAME="$TENANT_NAME >> ~/storperf_admin-rc
+  echo "OS_VOLUME_API_VERSION="$VOLUME_API_VERSION >> ~/storperf_admin-rc
+  echo "OS_PROJECT_NAME="$PROJECT_NAME >> ~/storperf_admin-rc
+  echo "OS_TENANT_ID="$TENANT_ID >> ~/storperf_admin-rc
+
+
+Step 1: Plug-in configuration file preparation
+++++++++++++++++++++++++++++++++++++++++++++++
+
+To install a plug-in, first you need to prepare a plug-in configuration file in
+YAML format and store it in the "plugin" directory. The plugin configration file
+work as the input of yardstick "plugin" command. Below is the Storperf plug-in
+configuration file sample:
+::
+
+  ---
+  # StorPerf plugin configuration file
+  # Used for integration StorPerf into Yardstick as a plugin
+  schema: "yardstick:plugin:0.1"
+  plugins:
+    name: storperf
+  deployment:
+    ip: 192.168.23.2
+    user: root
+    password: root
+
+In the plug-in configuration file, you need to specify the plug-in name and the
+plug-in deployment info, including node ip, node login username and password.
+Here the Storperf will be installed on IP 192.168.23.2 which is the Jump Host
+in my local environment.
+
+Step 2: Plug-in install/remove scripts preparation
+++++++++++++++++++++++++++++++++++++++++++++++++++
+
+Under "yardstick/resource/scripts directory", there are two folders: a "install"
+folder and a "remove" folder. You need to store the plug-in install/remove script
+in these two folders respectively.
+
+The detailed installation or remove operation should de defined in these two scripts.
+The name of both install and remove scripts should match the plugin-in name that you
+specified in the plug-in configuration file.
+For example, the install and remove scripts for Storperf are both named to "storperf.bash".
+
+
+Step 3: Install and remove Storperf
++++++++++++++++++++++++++++++++++++
+
+To install Storperf, simply execute the following command
+::
+
+  # Install Storperf
+  yardstick plugin install plugin/storperf.yaml
+
+removing Storperf from yardstick
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To remove Storperf, simply execute the following command
+::
+
+  # Remove Storperf
+  yardstick plugin remove plugin/storperf.yaml
+
+What yardstick plugin command does is using the username and password to log into the deployment target and then execute the corresponding install or remove script.
