 ## Usage
 
+**OpenVINO Environment**
+
+Before running any ort samples(Python/C++/C#) with the OpenVINOExecutionProvider it is must to set up the OpenVINO Environment Variables using the full installer package of OpenVINO.
+Initialize the OpenVINO environment by running the setupvars script as shown below. This is a required step:
+   * For Linux run till OpenVINO 2021.4 version:
+   ```
+      $ source <openvino_install_directory>/bin/setupvars.sh
+   ```
+   * For Linux run from OpenVINO 2022.1 version:
+   ```
+      $ source <openvino_install_directory>/setupvars.sh
+   ```
+   * For Windows run till OpenVINO 2021.4 version:
+   ```
+      C:\ <openvino_install_directory>\bin\setupvars.bat
+   ```
+   * For Windows run from OpenVINO 2022.1 version:
+   ```
+      C:\ <openvino_install_directory>\setupvars.bat
+   ```
+   **Note:** If you are using a dockerfile to use OpenVINO-EP, sourcing OpenVINO won't be possible within the dockerfile. You would have to explicitly set the LD_LIBRARY_PATH to point to OpenVINO libraries location. Refer our [dockerfile].(https://github.com/microsoft/onnxruntime/blob/master/dockerfiles/Dockerfile.openvino)

 **C#**
 
 To use csharp api for openvino execution provider create a custom nuget package. Follow the instructions [here](../build/inferencing.md#build-nuget-packages) to install prerequisites for nuget creation. Once prerequisites are installed follow the instructions to [build openvino](../build/eps.md#openvino) and add an extra flag `--build_nuget` to create nuget packages. Two nuget packages will be created Microsoft.ML.OnnxRuntime.Managed and Microsoft.ML.OnnxRuntime.Openvino.
