 # Building the OpenVINO™ Python API
 
 **Refer to ["How to build OpenVINO" in OpenVINO™ developer documentation](../../../../docs/dev/build.md) for general building instructions.**
-
 For each platform, you can build and install the API as a part of OpenVINO™ Toolkit or as a Python wheel.
-A Python wheel is a portable package that allows you to install OpenVINO™ in either your Python distribution or a dedicated virtual environment.

+## Using Python Wheels for OpenVINO™
+Wheels are portable python packages that are ready to install upon download. They are the de facto binary distributions in Python and avoid the compiling of extension modules and associated dependency issues on the user end. Thus, wheel installation is faster, smoother and makes the lives of both developers and users easier. The ```.whl``` format is the default preference for ```pip``` when you run a ```pip install``` command.
+
+OpenVino wheels for various platforms are available through [PyPI](https://pypi.org/project/openvino/#files) and allow you to install OpenVINO™ in either your Python distribution or a dedicated virtual environment.
+
+OpenVino builds two different wheels with separate ```setup.py``` files for [```openvino```](../wheel/setup.py) and [```openvino-dev```](../../../../tools/openvino_dev/setup.py). To build the wheels while building the project from source, your ```cmake``` command must include ```-DENABLE_PYTHON=ON``` and ```-DENABLE_WHEEL=ON```. Once built, the wheels should be available under ```openvino_install_dir/tools``` 
+
+While wheels are certainly convenient, please do note that development with wheels offers less customization than building from source and exporting ```PYTHONPATH``` and other environment variables to OpenVINO directories. Wheels are usually available for specific, packaged versions and may not contain the most recent changes that are available if you choose to clone the repo and build on your own.
