+# Feishu Bot Setup Guide
+
+[中文](./feishu-bot-setup.zh-CN.md)
+
+Use this guide to pair BitFun through a Feishu bot.
+
+## Setup Steps
+
+### Step 1
+
+Open the Feishu Developer Platform and log in:
+
+<https://open.feishu.cn/app?lang=en-US>
+
+### Step 2
+
+Create a custom app.
+
+### Step 3
+
+Add the bot feature:
+
+Features - Bot - Add
+
+### Step 4
+
+Add permission scopes:
+
+Permissions & Scopes - Add Scopes - Search for `im:` - Select all scopes that do not require approval - Add Scopes
+
+### Step 5
+
+Copy the app credentials:
+
+Credentials & Basic Info - App ID and App Secret
+
+### Step 6
+
+Open BitFun and start the Feishu bot connection:
+
+Remote Connect - IM Bot - Feishu Bot - Fill in App ID and App Secret - Connect
+
+### Step 7
+
+Return to the Feishu Developer Platform.
+
+### Step 8
+
+Configure event subscriptions:
+
+Events & callbacks - Event configuration - Subscription mode - Persistent connection - Save
+
+Then add message events:
+
+Add Events - Search for `im.message` - Select all - Confirm
+
+### Step 9
+
+Configure callback subscriptions:
+
+Events & callbacks - Callback configuration - Subscription mode - Persistent connection - Save
+
+Then add card action callbacks:
+
+Add callback - Search for `card.action.trigger` - Select it - Confirm
+
+### Step 10
+
+Publish the bot.
+
+### Step 11
+
+Open Feishu, search for the bot name, open the chat, enter any message, and send it.
+
+### Step 12
+
+Enter the 6-digit pairing code shown in BitFun Desktop, send it, and wait for the connection to succeed.

+# 飞书机器人配置指南
+
+[English](./feishu-bot-setup.md)
+
+适用于通过飞书机器人完成 BitFun 远程连接配对。
+
+## 配置步骤
+
+### 第一步
+
+打开飞书开发者平台并登录：
+
+<https://open.feishu.cn/app?lang=zh-CN>
+
+### 第二步
+
+创建企业自建应用。
+
+### 第三步
+
+添加机器人能力：
+
+添加应用能力 - 机器人 - 添加
+
+### 第四步
+
+开通权限：
+
+权限管理 - 开通权限 - 搜索 `im:` - 选择所有免审权限 - 确认开通权限
+
+### 第五步
+
+复制应用凭证：
+
+凭证与基础信息 - App ID 和 App Secret
+
+### 第六步
+
+打开 BitFun 并启动飞书机器人连接：
+
+远程连接 - IM 机器人 - 飞书机器人 - 填写 App ID 和 App Secret - 连接
+
+### 第七步
+
+回到飞书开发者平台。
+
+### 第八步
+
+配置事件订阅：
+
+事件与回调 - 事件配置 - 订阅方式 - 使用长连接接收事件 - 保存
+
+然后添加消息事件：
+
+添加事件 - 搜索 `im.message` - 全选 - 确认添加
+
+### 第九步
+
+配置回调订阅：
+
+事件与回调 - 回调配置 - 订阅方式 - 使用长连接接收事件 - 保存
+
+然后添加卡片动作回调：
+
+添加回调 - 搜索 `card.action.trigger` - 选中 - 确认添加
+
+### 第十步
+
+发布机器人。
+
+### 第十一步
+
+打开飞书应用，搜索机器人名称，点击机器人打开对话框，输入任意消息并发送。
+
+### 第十二步
+
+输入 BitFun Desktop 显示的 6 位配对码，发送后等待连接成功。
