     - Replace the `Host Name` value with the IP address of your ROS machine. Ensure that the `Host Port` is set to `10000`.
 
+    - If you are going to run ROS services with docker container introduced [below](#the-ros-side), fill `Host Name` and `Override Unity IP` with the loopback IP address `127.0.0.1`.
+
 1. To call the `Publish()` function, a UI element will be added for user input. In the Hierarchy window, right click to add a new UI > Button. Note that this will create a new Canvas parent as well. 
 	> Note: In the `Game` view, you will see the button appear in the bottom left corner as an overlay. In `Scene` view the button will be rendered on a canvas object that may not be visible.
    
 
 > Note: This project has been tested with Python 2 and ROS Melodic, as well as Python 3 and ROS Noetic.
 
-Most of the ROS setup has been provided via the `niryo_moveit` package. This section will describe the `.launch` files and start the necessary ROS nodes for communication.
+Most of the ROS setup has been provided via the `niryo_moveit` package. This section will describe the `.launch` files and start the necessary ROS nodes for communication. Two methods are provideds to launch ROS nodes and services: either using a ROS docker container or doing it manually in your own ROS environment.
+
+### Use Docker Container
+
+1. [Install Docker Engine](https://docs.docker.com/engine/install/)
+
+2. Build the ROS docker image
+
+  ```bash
+  cd /YOUR/UNITY-ROBOTICS-HUB/REPOSITORY/tutorials/pick_and_place &&
+  git submodule update --init --recursive &&
+  docker build -t unity-robotics:pick-and-place -f docker/Dockerfile .
+  ```
+
+3. Run ROS in a new docker container
+
+  ```bash
+  docker run -it --rm -p 10000:10000 -p 5005:5005 unity-robotics:pick-and-place part_2 /bin/bash
+  ```
+
+4. Terminate docker container
+
+  Press `Ctrl + C` or `Cmd + C` to terminate the docker container.
+
+### Manually Setup ROS
 
 1. The provided files require the following packages to be installed. ROS Melodic users should run the following commands if the packages are not already present:

 > This creates a set of planned trajectories, iterating through a pre-grasp, grasp, pick up, and place set of poses. Finally, this set of trajectories is sent back to Unity.
 
+### Use Docker Container
+
+1. If you are using ROS docker container and have not already build the ROS docker image. Follow the steps in [Part 2](2_ros_tcp.md) to build the `unity-robotics:pick-and-place` docker image.
+
+### Manually Setup ROS
+
 1. If you have not already built and sourced the ROS workspace since importing the new ROS packages, navigate to your ROS workplace, e.g. `Unity-Robotics-Hub/tutorials/pick_and_place/ROS/`, run `catkin_make && source devel/setup.bash`. Ensure there are no errors.
 
 1. If you have not already set the ROS parameter values in the `params.yaml`, navigate to `src/niryo_moveit/config/params.yaml` and open the file for editing. Follow the steps in [Part 2](2_ros_tcp.md) to configure the values.

 ## ROS–Unity Communication
+
+### Use Docker Container
+
+1. If you have not already, [build the ROS docker image](2_ros_tcp.md#use-docker-container) before executing the following command lines.
+
+2. Run ROS in a new docker container
+
+  ```bash
+  docker run -it --rm -p 10000:10000 -p 5005:5005 unity-robotics:pick-and-place part_3 /bin/bash
+  ```
+
+3. Terminate docker container
+
+    Press `Ctrl + C` or `Cmd + C` to terminate the docker container.
+
+### Manually Setup ROS
 
 1. Open a new terminal window in the ROS workspace. Once again, source the workspace.
