+
+## Lsky Telegram Upload Worker
+
+`lsky-telegram-worker.js` 用于把 Telegram 私聊发送的图片或图片文件上传到 Lsky Pro。上传成功后，Bot 会回复 Markdown 图片链接，并使用 Telegram HTML `<pre>` 代码块渲染，便于 Android 客户端点击复制。
+
+### 功能
+
+- 支持 Telegram `photo` 和图片类 `document`。
+- 支持 Telegram `media_group_id` 相册收集后批量上传。
+- 默认单文件大小限制为 `500.00 MB`，可用 `MAX_FILE_MB` 覆盖。
+- 默认上传队列最多收 `500` 张，可用 `MAX_UPLOAD_QUEUE_IMAGES` 覆盖。
+- 返回格式为 `![filename](url)`，并关闭网页预览。
+- 通过 `ALLOWED_TELEGRAM_USER_IDS` 限制可用用户。
+
+### 必需绑定和环境变量
+
+| 名称 | 说明 |
+| --- | --- |
+| `DB` | Cloudflare D1 数据库绑定名，用于暂存相册队列 |
+| `TELEGRAM_BOT_TOKEN` | Telegram Bot Token |
+| `TELEGRAM_WEBHOOK_SECRET` | Telegram Webhook secret token，同时用于 `/init` 初始化鉴权 |
+| `ALLOWED_TELEGRAM_USER_IDS` | 允许使用的 Telegram user id，多个用英文逗号分隔 |
+| `LSKY_API_URL` | Lsky Pro 上传 API 地址 |
+| `LSKY_TOKEN` | Lsky Pro API token |
+
+### 可选环境变量
+
+| 名称 | 默认值 | 说明 |
+| --- | --- | --- |
+| `MAX_FILE_MB` | `500.00` | 单个 Telegram 图片/文件大小上限，单位 MB |
+| `MAX_UPLOAD_QUEUE_IMAGES` | `500` | 单个上传队列最多暂存图片数量 |
+| `ALBUM_WAIT_SECONDS` | `5` | 相册收集等待秒数 |
+| `LSKY_PERMISSION` | `1` | 传给 Lsky Pro 的 `permission` |
+| `LSKY_STRATEGY_ID` | 空 | 传给 Lsky Pro 的 `strategy_id` |
+
+### 部署流程
+
+1. 创建 Telegram Bot，拿到 `TELEGRAM_BOT_TOKEN`。
+2. 创建 Cloudflare D1 数据库，并在 Worker 中绑定为 `DB`。
+3. 创建 Worker，把 [lsky-telegram-worker.js](lsky-telegram-worker.js) 作为 Worker 代码。
+4. 配置上方环境变量。
+5. 访问 `https://<WORKER_URL>/init?secret=<TELEGRAM_WEBHOOK_SECRET>` 初始化 D1 表。
+6. 设置 Telegram Webhook：
+
+```bash
+curl -X POST "https://api.telegram.org/bot<TELEGRAM_BOT_TOKEN>/setWebhook" \
+  -d "url=<WORKER_URL>/webhook" \
+  -d "secret_token=<TELEGRAM_WEBHOOK_SECRET>"
+```
+
+7. 访问 Worker 根路径，若返回 `Lsky Telegram Worker OK - code-block-max500mb-queue500-2026-05-27`，说明 Worker 基本可用。
+
+## Telegram Bot Worker
 
 `tg-bot.js` 是一个部署在 Cloudflare Workers 上的 Telegram 双向私聊中继 Bot（版本 v3.68）。它会把用户私聊消息转发到管理员论坛群的独立 topic 中，管理员在对应 topic 内回复即可把消息发回用户，同时提供验证、过滤、封禁、备注、自动回复、备份和 Telegram 内联管理面板。
