+Bare Metal context example
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Let's assume there are three servers acting as TG, sample VNF DUT and jump host.
+
+Perform following steps to install NSB:
+
+1. Clone Yardstick repo to jump host.
+2. Add TG and DUT servers to ``yardstick-baremetal`` group in
+   ``install-inventory.ini`` file to install NSB and dependencies. Install
+   python on servers.
+3. Start deployment using docker image based on Ubuntu 16:
+
+.. code-block:: console
+
+   ./nsb_setup.sh
+
+4. Reboot bare metal servers.
+5. Enter to yardstick container and modify pod yaml file and run tests.

+Standalone context example for Ubuntu 18
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Let's assume there are three servers acting as TG, sample VNF DUT and jump host.
+Ubuntu 18 is installed on all servers.
+
+Perform following steps to install NSB:
+
+1. Clone Yardstick repo to jump host.
+2. Add TG server to ``yardstick-baremetal`` group in
+   ``install-inventory.ini`` file to install NSB and dependencies.
+   Add server where VM with sample VNF will be deployed to
+   ``yardstick-standalone`` group in ``install-inventory.ini`` file.
+   Target VM image named ``yardstick-nsb-image.img`` will be placed to
+   ``/var/lib/libvirt/images/``.
+   Install python on servers.
+3. Modify ``nsb_setup.sh`` on jump host:
+
+.. code-block:: console
+
+   ansible-playbook \
+   -e IMAGE_PROPERTY='nsb' \
+   -e OS_RELEASE='bionic' \
+   -e INSTALLATION_MODE='container_pull' \

+
+.. code-block:: console

+   ./nsb_setup.sh -i opnfv/yardstick-ubuntu-18.04:latest -o <openrc_file>
+
+5. Reboot servers.
