 The VMware Cloud on AWS API and samples are currently available as a preview and are subject to change in the future.
 
 ## Quick Start Guide
-This document will walk you through getting up and running with the Python SDK Samples.
-Prior to running the samples you will need to setup a vCenter test environment and
-install local Python packages, the following steps will take you through this process.
 
-Before you can run the SDK samples we'll need to walk you through the following steps:
+### Prepare a Python Development Environment
 
-1. Installing the required Python packages
+We recommend you to install latest [Python](http://docs.python-guide.org/en/latest/starting/installation/) and
-2. Setting up a vSphere test environment
+[pip](https://pypi.python.org/pypi/pip/) on your system.  
-3. Running SDK Samples setup script
 
-### Installing the required Python Packages
+A Python virtual environment is also highly recommended.
-**Note:** The SDK requires Python v2.7+ (preferably v3.6) to run the setup/samples,
+* [Install a virtual env for Python 2](https://virtualenv.pypa.io/en/stable/)
-please make sure you have the appropriate version installed before continuing.
+* [Install a virtual env for Python 3](https://docs.python.org/3/tutorial/venv.html)
-If you are on macOS/OSX/Linux, please note that the system installed version of
-Python may be outdated and/or not be intended for development and we recommended you [install Python](http://docs.python-guide.org/en/latest/starting/installation/) yourself before installing the required packages. [Virtualenv](https://virtualenv.pypa.io/en/stable/) is also highly recommended.
 
-The required packages are:
+### Installing Required Python Packages
-
-* pyVmomi
-* suds (suds-jurko for python3+)
-* vapi-client-bindings
-* vmc-client-bindings
-* vapi-vmc-client
-
-These dependencies are listed in the requirements.txt file and installed using "pip install"; For more details on how to install python packages using pip please refer to the [pip user guide](http://pip.readthedocs.io/en/latest/user_guide/).
 
 ```cmd
-pip install --upgrade --force-reinstall -r requirements.txt --extra-index-url <file:///abs_path/to/sdk/lib/>
+git clone https://github.com/vmware/vsphere-automation-sdk-python.git
+cd vsphere-automation-sdk-python
+pip install --upgrade --force-reinstall -r requirements.txt --extra-index-url file:///`pwd`/lib
 ```
 
 **NOTE:** The SDK also requires OpenSSL 1.0.1+ if you want to connect to vSphere 6.5+ in order to support TLS1.1 & 1.2
 
-### Setting up a vSphere Test Environment
+### Connect to a vCenter Server
-**NOTE:** The samples are intended to be run against a freshly installed **non-Production** vSphere setup as the scripts may make changes to the test environment and in some cases can destroy items when needed.
 
-To run the samples a vSphere test environment is required with the following configuration
+```python
-* 1 vCenter Server
+import requests
-* 2 ESX hosts
+import urllib3
-* 1 NFS Datastore with at least 3GB of free capacity
+from vmware.vapi.vsphere.client import create_vsphere_client
+session = requests.session()
 
-Please have the details of these available but do not have any configuration pre-created on vCenter server or ESXi Hosts, for example there should be no existing datacenters, clusters or attached hosts on the vCenter server.
+# Disable cert verification for demo purpose. 
+# This is not recommended in a production environment.
+session.verify = False
 
-### Running the SDK Sample Setup Script
+# Disable the secure connection warning for demo purpose.
-Before executing the samples we'll need to setup the vSphere test environment using one of the sample scripts. Before we run the script we'll need to edit one of the files and provide IP addresses for the various machine instances.
+# This is not recommended in a production environment.
+urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

+# Connect to a vCenter Server using username and password
+vsphere_client = create_vsphere_client(server='<vc_ip>', username='<vc_username>', password='<vc_password>', session=session)

+#### Running the SDK Sample Setup Script
+
+Before executing the samples we'll need to setup the vSphere test environment using one of the sample scripts (samples/vsphere/vcenter/setup/main.py). The script will perform the following:
+
+* Create 2 test Datacenters 
+* Create a test Cluster
+* Create Test Folders for VM Storage
+* Attach the hosts
+* Create a Distributed Switch
+* Create a Distributed Portgroup
+* Attach the NFS datastore (if Selected) to the hosts

+* Create directories to add sample ports

 ## Resource Maintenance
 ### Maintenance Ownership
+
 Ownership of any and all submitted samples are maintained by the submitter.
+
 ### Filing Issues
+
 Any bugs or other issues should be filed within GitHub by way of the repository’s Issue Tracker.
+
 ### Resolving Issues
+
 Any community member can resolve issues within the repository, however only the board member can approve the update. Once approved, assuming the resolution involves a pull request, only a board member will be able to merge and close the request.
 
 ### VMware Sample Exchange
+
 It is highly recommended to add any and all submitted samples to the VMware Sample Exchange:  <https://code.vmware.com/samples>
 
 Sample Exchange can be allowed to access your GitHub resources, by way of a linking process, where they can be indexed and searched by the community. There are VMware social media accounts which will advertise resources posted to the site and there's no additional accounts needed, as the VMware Sample Exchange uses MyVMware credentials.
