-OpenVINO™ Extension API allows you to register custom operations to support models with operations which OpenVINO™ does not support out-of-the-box. While this process historically involved writing C++ code and constructing a separate shared library to be subsequently loaded into Python using the ``add_extension`` API, it is now also possible to implement custom operations directly within the Python API.
+OpenVINO™ Extension API allows you to register custom operations to support models with operations which OpenVINO™ does not support out-of-the-box. While this process historically involved writing C++ code and constructing a separate shared library to be subsequently loaded into Python using the ``add_extension`` API, it is now also possible to implement custom operations directly within the Python API with some known limitations. Operations implemented in python still won't be loaded into the runtime and may be used for building your own Model. 
 
 For those who still wish to use C++, the capability to create a shared library with custom operation implementations is maintained. Please refer to :ref:`Create library with extensions <create_a_library_with_extensions>` for more details on library creation and usage. The remaining part of this document describes how to implement an operation class using both the C++ API and Python API.
