+***************
+Using the tool
+***************
+
+Charts folder contains three different charts - ``proxchart, testpmd chart and trex chart``. Any of the one can be used for testing.
+Pyscript folder contains ``main.py`` - the main python script that depploys the helm chart of user's choice and returns important configuration of the charts, such as PodIP, Cluster IP, Interface IPs etc.
+
+************************
+Important Configurations
+************************
+
+In order to run the python script, we need to install Pipenv to create virtual environment.
+
+Steps:
+
+1. Install
+
+.. code-block:: console
+
+    pip install --user pipenv
+
+2. To activate the environment
+
+.. code-block:: console
+
+    pipenv shell
+
+The last command will automatically read Pipfile.lock and will create an virtual environment.
+
+Once this configuration is done. We can move on to run our python script.
+
+*************************************************
+Procedure to automatically deploy the helm chart
+*************************************************
+
+Steps:
+
+1. After activating your virtual environment, run the ``main.py``.
+
+.. code-block:: console
+
+    python main.python
+
+2. Enter the location of the chart you want to deploy.
+
+For example, lets deploy proxchart
+
+.. code-block:: console
+
+    Enter the location of helm chart: ../charts/proxchart
+
+3. The last command will execute the entire ``main.py`` and will return all the required information about the chart.

+Future Enhancements

+
+In future, more information can be extracted by adding new functions to the file. The process of getting interfaces using regex can be made more proficient.
