+Yardstick Installation
+======================
+
+Abstract
+--------
+
+Yardstick currently supports installation on Ubuntu 14.04 or by using a Docker
+image. Detailed steps about installing Yardstick using both of these options
+can be found below.
+
+To use Yardstick you should have access to an OpenStack environment,
+with at least Nova, Neutron, Glance, Keystone and Heat installed.
+
+The steps needed to run Yardstick are:
+
+1. Install Yardstick and create the test configuration .yaml file.
+2. Build a guest image and load the image into the OpenStack environment.
+3. Create a Neutron external network and load OpenStack environment variables.
+4. Run the test case.
+
+
+Installing Yardstick on Ubuntu 14.04
+------------------------------------
+
+.. _install-framework:
+
+Installing Yardstick framework
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Install dependencies:
+::
+
+  sudo apt-get install python-virtualenv python-dev
+  sudo apt-get install libffi-dev libssl-dev git
+
+Create a python virtual environment, source it and update setuptools:
+::
+
+  virtualenv ~/yardstick_venv
+  source ~/yardstick_venv/bin/activate
+  easy_install -U setuptools
+
+Download source code and install python dependencies:
+::
+
+  git clone https://gerrit.opnfv.org/gerrit/yardstick
+  cd yardstick
+  python setup.py install
+
+There is also a YouTube video, showing the above steps:

+
+Installing extra tools
+^^^^^^^^^^^^^^^^^^^^^^
+yardstick-plot
+""""""""""""""
+Yardstick has an internal plotting tool ``yardstick-plot``, which can be installed
+using the following command:
+::
+
+  python setup.py develop easy_install yardstick[plot]
+
+.. _guest-image:
+
+Building a guest image
+^^^^^^^^^^^^^^^^^^^^^^
+Yardstick has a tool for building an Ubuntu Cloud Server image containing all
+the required tools to run test cases supported by Yardstick. It is necessary to
+have sudo rights to use this tool.
+
+This image can be built using the following command while in the directory where
+Yardstick is installed (``~/yardstick`` if the framework is installed
+by following the commands above):
+::
+
+  sudo ./tools/yardstick-img-modify tools/ubuntu-server-cloudimg-modify.sh
+
+**Warning:** the script will create files by default in:
+``/tmp/workspace/yardstick`` and the files will be owned by root!
+
+The created image can be added to OpenStack using the ``glance image-create`` or
+via the OpenStack Dashboard.
+
+Example command:
+::
+
+  glance --os-image-api-version 1 image-create \
+  --name yardstick-trusty-server --is-public true \
+  --disk-format qcow2 --container-format bare \
+  --file /tmp/workspace/yardstick/yardstick-trusty-server.img
+
+
+Installing Yardstick using Docker
+---------------------------------
+
+Yardstick has two Docker images, first one (**Yardstick-framework**) serves as a
+replacement for installing the Yardstick framework in a virtual environment (for
+example as done in :ref:`install-framework`), while the other image is mostly for
+CI purposes (**Yardstick-CI**).
+
+Yardstick-framework image
+^^^^^^^^^^^^^^^^^^^^^^^^^
+Download the source code:
+
+::
+
+  git clone https://gerrit.opnfv.org/gerrit/yardstick
+
+Build the Docker image and tag it as *yardstick-framework*:
+
+::
+
+  cd yardstick
+  docker build -t yardstick-framework .
+
+Run the Docker instance:
+
+::
+
+  docker run --name yardstick_instance -i -t yardstick-framework
+
+To build a guest image for Yardstick, see :ref:`guest-image`.
+
+Yardstick-CI image
+^^^^^^^^^^^^^^^^^^
+Pull the Yardstick-CI Docker image from Docker hub:
+
+::
+
+  docker pull opnfv/yardstick-ci
+
+Run the Docker image:
+
+::
+
+  docker run \
+   --privileged=true \
+    --rm \
+    -t \
+    -e "INSTALLER_TYPE=${INSTALLER_TYPE}" \
+    -e "INSTALLER_IP=${INSTALLER_IP}" \
+    opnfv/yardstick-ci \
+    run_benchmarks
+
+Where ``${INSTALLER_TYPE}`` can be fuel, foreman or compass and ``${INSTALLER_IP}``
+is the installer master node IP address (i.e. 10.20.0.2 is default for fuel).
+
+Basic steps performed by the **Yardstick-CI** container:
+
+1. clone yardstick and releng repos
+2. setup OS credentials (releng scripts)
+3. install yardstick and dependencies
+4. build yardstick cloud image and upload it to glance
+5. upload cirros-0.3.3 cloud image to glance
+6. run yardstick test scenarios
+7. cleanup
+
+
+OpenStack parameters and credentials
+------------------------------------
+
+Yardstick-flavor
+^^^^^^^^^^^^^^^^
+Most of the sample test cases in Yardstick are using an OpenStack flavor called
+*yardstick-flavor* which deviates from the OpenStack standard m1.tiny flavor by the
+disk size - instead of 1GB it has 3GB. Other parameters are the same as in m1.tiny.
+
+Environment variables
+^^^^^^^^^^^^^^^^^^^^^
+Before running Yardstick it is necessary to export OpenStack environment variables
+from the OpenStack *openrc* file (using the ``source`` command) and export the
+external network name ``export EXTERNAL_NETWORK="external-network-name"``,
+the default name for the external network is ``net04_ext``.
+
+Credential environment variables in the *openrc* file have to include at least:
+
+* OS_AUTH_URL
+* OS_USERNAME
+* OS_PASSWORD
+* OS_TENANT_NAME
+
+Yardstick default key pair
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+Yardstick uses a SSH key pair to connect to the guest image. This key pair can
+be found in the ``resources/files`` directory. To run the ``ping-hot.yaml`` test
+sample, this key pair needs to be imported to the OpenStack environment.
+
+
+Examples and verifying the install
+----------------------------------
+
+It is recommended to verify that Yardstick was installed successfully
+by executing some simple commands and test samples. Below is an example invocation
+of yardstick help command and ping.py test sample:
+::
+
+  yardstick –h
+  yardstick task start samples/ping.yaml
+
+Each testing tool supported by Yardstick has a sample configuration file.
+These configuration files can be found in the **samples** directory.
+
+Example invocation of ``yardstick-plot`` tool:
+::
+
+  yardstick-plot -i /tmp/yardstick.out -o /tmp/plots/
+
+Default location for the output is ``/tmp/yardstick.out``.
+
+More info about the tool can be found by executing:
+::
+
+  yardstick-plot -h
