+# TypeScript/Node.js SDK 使用说明
+
+## 要求
+
+- Node.js >= 8.x
+
+## 安装
+
+你可以使用 `npm` 来管理你的依赖，并通过下面命令安装依赖并写入 package.json
+
+```sh
+$ npm install @alicloud/facebody20191230 -S
+```
+
+## 快速使用
+
+在您开始之前，您需要注册阿里云帐户并获取您的[凭证](https://usercenter.console.aliyun.com/#/manage/ak)。
+SDK 使用 [credentials-nodejs](https://github.com/aliyun/credentials-nodejs/blob/master/README-CN.md) 来管理凭证。
+
+## 使用示例
+
+```javascript
+import Client from "@alicloud/facebody20191230";
+import * as Util from "@alicloud/tea-util";
+// 创建客户端
+const client = new Client({
+  endpoint: "your endpoint",
+  accessKeyId: "your access key id",
+  accessKeySecret: "your access key secret",
+  type: "access_key",
+  regionId: "cn-hangzhou"
+});
+// 初始化 runtimeObject
+const runtimeObject = new Util.RuntimeOptions({});
+// 初始化 request
+const addFaceEntityRequest = new AddFaceEntityRequest({
+  dbName: "dbName",
+  entityId: "entityId",
+  labels: "labels"
+});
+// 调用 api
+const res = await client.addFaceEntity(addFaceEntityRequest, runtimeObject);
+```
+
+## 参数说明
+
+```javascript
+const Config = {
+  AccessKeyId: "AccessKeyId", // AccessKey Id
+  AccessKeySecret: "AccessKeySecret", // AccessKey Secret
+  Type: "Type", // 凭证类型，如有疑问请参考 https://github.com/aliyun/credentials-nodejs/blob/master/README-CN.md#%E5%87%AD%E8%AF%81%E7%B1%BB%E5%9E%8B
