+| Type | Requirements | Features |
 | --- | --- | --- |
-| **个人订阅号** | 个人可申请 | 收到消息时会回复一条提示，回复生成后需用户主动发消息获取 |
-| **企业服务号** | 企业申请，需通过微信认证开通客服接口 | 回复生成后可主动推送给用户 |

-### 配置步骤
+### Setup Steps
 
-这些配置需要和 [微信公众号后台](https://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev) 中的保持一致，进入页面后，在左侧菜单选择 **设置与开发 → 基本配置 → 服务器配置**，按下图进行配置：
+These configurations must be consistent with the [WeChat Official Account Platform](https://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev). Navigate to **Settings & Development → Basic Configuration → Server Configuration** and configure as shown below:
 
 <img src="https://cdn.link-ai.tech/doc/20260228103506.png" width="480"/>
 
-1. 在公众平台启用开发者密码（对应配置 `wechatmp_app_secret`），并将服务器 IP 填入白名单
-2. 按上图填写 `config.json` 中与公众号相关的配置，要与公众号后台的配置一致
-3. 启动程序，启动后会监听 80 端口（若无权限监听，则在启动命令前加上 `sudo`；若 80 端口已被占用，则关闭该占用进程）
-4. 在公众号后台 **启用服务器配置** 并提交，保存成功则表示已成功配置。注意 **"服务器地址(URL)"** 需要配置为 `http://{HOST}/wx` 的格式，其中 `{HOST}` 可以是服务器的 IP 或域名
+1. Enable the developer secret on the platform (corresponds to `wechatmp_app_secret`), and add the server IP to the whitelist
+2. Fill in the `config.json` with the official account parameters matching the platform configuration
+3. Start the program, which listens on port 80 (use `sudo` if you don't have permission; stop any process occupying port 80)
+4. **Enable server configuration** on the official account platform and submit. A successful save means the configuration is complete. Note that the **"Server URL"** must be in the format `http://{HOST}/wx`, where `{HOST}` can be the server IP or domain
 
-随后关注公众号并发送消息即可看到以下效果：
+After following the account and sending a message, you should see the following result:
 
 <img src="https://cdn.link-ai.tech/doc/20260228103522.png" width="720"/>
 
-由于受订阅号限制，回复内容较短的情况下（15s 内），可以立即完成回复，但耗时较长的回复则会先回复一句 "正在思考中"，后续需要用户输入任意文字主动获取答案，而服务号则可以通过客服接口解决这一问题。
+Due to subscription account limitations, short replies (within 15s) can be returned immediately, but longer replies will first send a "Thinking..." placeholder, requiring users to send any text to retrieve the answer. Enterprise service accounts can solve this with the customer service API.
 
 <Tip>
-  **语音识别**：可利用微信自带的语音识别功能，需要在公众号管理页面的 "设置与开发 → 接口权限" 页面开启 "接收语音识别结果"。
+  **Voice Recognition**: You can use WeChat's built-in voice recognition. Enable "Receive Voice Recognition Results" under "Settings & Development → API Permissions" on the official account management page.
 </Tip>
 
-## 二、企业服务号
+## 2. Enterprise Service Account
 
-企业服务号与上述个人订阅号的接入过程基本相同，差异如下：
+The setup process for enterprise service accounts is essentially the same as personal subscription accounts, with the following differences:
 
-1. 在公众平台申请企业服务号并完成微信认证，在接口权限中确认已获得 **客服接口** 的权限
-2. 在 `config.json` 中设置 `"channel_type": "wechatmp_service"`，其他配置与上述订阅号相同
-3. 交互效果上，即使是较长耗时的回复，也可以主动推送给用户，无需用户手动获取
+1. Register an enterprise service account on the platform and complete WeChat certification. Confirm that the **Customer Service API** permission has been granted
+2. Set `"channel_type": "wechatmp_service"` in `config.json`; other configurations remain the same
+3. Even for longer replies, they can be proactively pushed to users without requiring manual retrieval
