+Automatic installation of Yardstick using ansible
+-------------------------------------------------
+
+Automatic installation can be used as an alternative to the manual.
+Yardstick can be installed on the bare metal and to the container. Yardstick
+container can be either pulled or built.
+
+Bare metal installation
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Use ansible script ``install.yaml`` to install Yardstick on Ubuntu server:
+
+.. code-block:: console
+
+    ansible-playbook -i install-inventory.ini install.yaml \
+    -e YARDSTICK_DIR=<path to Yardstick folder>
+
+.. note:: By default ``INSTALLATION_MODE`` is ``baremetal``.
+
+.. note:: By default Ubuntu 16.04 is chosen (xenial). It can be changed to
+   Ubuntu 18.04 (bionic) by passing ``-e OS_RELEASE=bionic`` parameter.
+
+.. note:: To install Yardstick in virtual environment pass parameter
+   ``-e VIRTUAL_ENVIRONMENT=True``.
+
+To build Yardstick NSB image pass ``IMG_PROPERTY=nsb`` as input parameter:
+
+.. code-block:: console
+
+    ansible-playbook -i install-inventory.ini install.yaml \
+    -e IMAGE_PROPERTY=nsb \
+    -e YARDSTICK_DIR=<path to Yardstick folder>
+
+.. note:: In this ``INSTALLATION_MODE`` mode either Yardstick image or SampleVNF
+   images will be built. Image type is defined by parameter ``IMAGE_PROPERTY``.
+   By default Yardstick image will be built.
+
+Container installation
+^^^^^^^^^^^^^^^^^^^^^^
+
+Use ansible script ``install.yaml`` to pull or build Yardstick
+container. To pull Yardstick image and start container run:
+
+.. code-block:: console
+
+    ansible-playbook -i install-inventory.ini install.yaml \
+    -e YARDSTICK_DIR=<path to Yardstick folder> \
+    -e INSTALLATION_MODE=container_pull
+
+.. note:: In this ``INSTALLATION_MODE`` mode either Yardstick image or SampleVNF
+   images will be built. Image type is defined by variable ``IMG_PROPERTY`` in
+   file ``ansible/group_vars/all.yml``. By default Yardstick image will be
+   built.
+
+.. note:: Open question: How to know if Docker image is built on Ubuntu 16.04 and 18.04?
+   Do we need separate tag to be used?
+
+To build Yardstick image run:
+
+.. code-block:: console
+
+    ansible-playbook -i install-inventory.ini install.yaml \
+    -e YARDSTICK_DIR=<path to Yardstick folder> \
+    -e INSTALLATION_MODE=container
+
+.. note:: In this ``INSTALLATION_MODE`` mode neither Yardstick image nor SampleVNF
+   image will be built.
+
+.. note:: By default Ubuntu 16.04 is chosen (xenial). It can be changed to
+   Ubuntu 18.04 (bionic) by passing ``-e OS_RELEASE=bionic`` parameter.
