+## 📚 What is OpenVINO™ C# API ?
+
+[OpenVINO™](www.openvino.ai)  is an open-source toolkit for optimizing and deploying AI inference.
+
+- Boost deep learning performance in computer vision, automatic speech recognition, natural language processing and other common tasks
+- Use models trained with popular frameworks like TensorFlow, PyTorch and more
+- Reduce resource demands and efficiently deploy on a range of Intel® platforms from edge to cloud
+
+&emsp;    This project is mainly based on OpenVINO ™ OpenVINO launched by tool kit ™  C # API, aimed at driving OpenVINO ™   Application on the C # platform.
+
+&emsp;    OpenVINO ™  The C # API is based on OpenVINO ™   C API development, supported platforms and OpenVINO ™  Consistent, please refer to OpenVINO for specific information ™。

+
+&emsp;    C # supports NuGet Package installation and one-stop installation on platforms such as Linux and Window. Therefore, in order to facilitate more users, a NuGet Package for use on the Window platform has been released for the convenience of everyone.
+
+| Package                 | Description                                                  | Link                                                         |

+
+## ⚙ How to install OpenVINO™ C# API?
+
+The following article provides installation methods for OpenVINO™ C# API on different platforms, which can be installed according to your own platform.
+
+- [Windows](docs/en/windows_install.md)
+
+- [Linux](docs/en/linux_install.md)
+
+## 🏷How to use OpenVINO™ C# API?
+
+- **Quick start**
+  - [Deploying the Yolov8 full series model using OpenVINO™ C# API](demos/yolov8/README.md)
+
+- **Simple usage**
+
+If you don't know how to use it, simply understand the usage method through the following code.
+
+```c#
+namespace test 
+{
+    internal class Program
+    {
+        static void Main(string[] args)
+        {
+            Core core = new Core();
+            Model model = core.read_model("./model.xml");
+            CompiledModel compiled_model = core.compiled_model(model, "AUTO"); 
+            InferRequest infer_request = compiled_model.create_infer_request(); 
+            Tensor input_tensor = infer_request.get_tensor("images"); 
+            infer_request.infer(); 
+            Tensor output_tensor = infer_request.get_tensor("output0"); 
+            core.free(); 
+        }
+    }
+}
+```
+
+The classes and objects encapsulated in the project, such as Core, Model, Tensor, etc., are implemented by calling the C API interface and have unmanaged resources. They need to be handled by calling the **dispose() ** method, otherwise memory leakage may occur.

+## 📚 简介
+
+[OpenVINO™ ](www.openvino.ai)是一个用于优化和部署 AI 推理的开源工具包。
+
+- 提升深度学习在计算机视觉、自动语音识别、自然语言处理和其他常见任务中的性能
+- 使用流行框架（如TensorFlow，PyTorch等）训练的模型
+- 减少资源需求，并在从边缘到云的一系列英特尔®平台上高效部署
+
+&emsp;    该项目主要是基于OpenVINO™工具套件推出的 OpenVINO™ C# API，旨在推动  OpenVINO™  在C#平台的应用。
+
+&emsp;    OpenVINO™ C# API 由于是基于 OpenVINO™  C API 开发，所支持的平台与OpenVINO™ 一致，具体信息可以参考 OpenVINO™。

+
+## ⚙ 如何安装
+
+以下文章提供了OpenVINO™ C# API在不同平台的安装方法，可以根据自己使用平台进行安装。
+
+- [Windows](docs/cn/windows_install.md)
+
+- [Linux](docs/cn/linux_install.md)
+
+## 🏷开始使用
+
+- **快速体验**
+
+  [使用OpenVINO™ C# API部署Yolov8全系列模型](demos/yolov8/README_cn.md)
+
+- **使用方法**
+
+如果你不知道如何使用，通过下面代码简单了解使用方法。
+
+```c#
+namespace test 
+{
+    internal class Program
+    {
+        static void Main(string[] args)
+        {
+            Core core = new Core();  // 初始化 Core 核心
+            Model model = core.read_model("./model.xml");  // 读取模型文件
+            CompiledModel compiled_model = core.compiled_model(model, "AUTO");  // 将模型加载到设备
+            InferRequest infer_request = compiled_model.create_infer_request();  // 创建推理通道
+            Tensor input_tensor = infer_request.get_tensor("images");  // 获取输入节点Tensor
+            infer_request.infer();  // 模型推理
+            Tensor output_tensor = infer_request.get_tensor("output0");  // 获取输出节点Tensor
+            core.free();  // 清理 Core 非托管内存
+        }
+    }
+}
+```
+
+项目中所封装的类、对象例如Core、Model、Tensor等，通过调用 C api 接口实现，具有非托管资源，需要调用**dispose()**方法处理，否则就会出现内存泄漏。
