-### Requirement for Python Client
+### Python Client Module
 
-    sudo apt-get install python-pip
-    pip install protobuf (may need to run as sudo)
+VDMS offers the Python Client Module through the pip package manager, 
+and it is compatible with Python 2.7+ and 3.3+. 
+pip (or pip2 and pip3) will automatically install dependencies (protobuf).
 
-    Add VDMS Python module to PYPATH:
-    export PYTHONPATH="${PYTHONPATH}:<path_to_vdms>/client/python/vdms"
-    # Example:
-    export PYTHONPATH="${PYTHONPATH}:/opt/intel/vdms/client/python/vdms"
+    pip install vdms
