+# 使用 Sequelize 连接 OceanBase
+
+[English](README.md) | 简体中文
+
+本文介绍如何通过 Sequelize 连接 OceanBase 数据库。
+
+## 准备工作
+
+确保 Node.js 和 npm 已经安装。
+
+## 项目使用
+
+拉取项目并进入相应目录:
+
+```bash
+git clone [email protected]:oceanbase/ob-samples.git
+cd javascript/sequelize
+```
+
+安装依赖:
+
+```bash
+npm install
+```
+
+修改 `index.js` 中的数据库连接串:
+
+```javascript
+const sequelize = new Sequelize("mysql://root:@127.0.0.1:2881/test", {
+  dialect: "mysql",
+  logging: false,
+});
+```
+
+执行 `index.js` 中的示例代码:
+
+```bash
+node index.js
+```
+
+输出以下内容，说明执行成功:
+
+```bash
+[
+  {
+    "id": 1,
+    "email": "[email protected]",
+    "name": "Alice"
+  }
+]
+```
+
+查看对应的 `users` 表，数据已正常插入:
+
+```bash
+mysql> select * from users;
++----+-----------------+-------+
+| id | email           | name  |
++----+-----------------+-------+
+|  1 | [email protected] | Alice |
++----+-----------------+-------+
+1 row in set (0.02 sec)
+```

+# Connect to OceanBase with Sequelize
+
+English | [简体中文](README-CN.md)
+
+This document describes how to connect to OceanBase with Sequelize.
+
+## 准备工作
+
+Make sure `Node.js` and `npm` are installed.
+
+## 项目使用
+
+Clone the project and navigate to the appropriate directory:
+
+```bash
+git clone [email protected]:oceanbase/ob-samples.git
+cd javascript/sequelize
+```
+
+Install dependencies:
+
+```bash
+npm install

+
+Modify the connection string in the `index.js` file:
+
+```javascript
+const sequelize = new Sequelize("mysql://root:@127.0.0.1:2881/test", {
+  dialect: "mysql",
+  logging: false,
+});
+```
+
+Execute `index.js`:
+
+```bash
+node index.js
+```
+
+The output should be as follows, indicating successful execution:

+```bash
+[
+  {
+    "id": 1,
+    "email": "[email protected]",
+    "name": "Alice"
+  }
+]
+```
+
+Check the corresponding `users` table and the data has been inserted:
+
+```bash
+mysql> select * from users;
++----+-----------------+-------+
+| id | email           | name  |
++----+-----------------+-------+
+|  1 | [email protected] | Alice |
++----+-----------------+-------+
+1 row in set (0.02 sec)
