+**External Download Sources (Advanced):**
+
+varManager can search for missing var packages from external sources (Pixeldrain, Mediafire) and local torrent files as a fallback when Hub doesn't have them:
+
+1. **Link Files Setup:**
+   - Create a `data/links/` folder in your varManager directory
+   - Add `.txt` files containing var package links (one per line)
+   - Format: `VarName.var [whitespace] URL`
+   - Example: `Creator.PackageName.1.var https://pixeldrain.com/u/ABC123`
+
+2. **Torrent Files Setup:**
+   - Create a `data/links/torrents/` subfolder
+   - Place `.torrent` files that contain var packages
+   - The scanner detects var names in torrent metadata and can download missing vars via aria2
+
+3. **Pre-populated Link Files:**
+   - The repo includes working link files in `data/links/` folder (gitignored)
+   - These are real, curated link databases ready to use
+   - Files are included in the repository but not in public releases
+
+4. **Usage:**
+   - Go to Missing Vars page
+   - Enable "External Sources" checkbox
+   - Select desired sources (Pixeldrain, Mediafire)
+   - Click "Fetch Links (Hub + External)"
+   - Hub results always take priority; external sources fill gaps
+
+**Torrent Downloads (aria2):**
+- Place `aria2c.exe` in `data/aria2c.exe`
+- When a missing var has torrent hits and no direct URL, varManager uses aria2 to download only the required `.var` files
+- Downloads go to `varspath\AddonPackages\tmp` and completed `.var` files are moved to `varspath`
+- `.torrent` files in `data/links/torrents/` are never deleted
+
+**Note:** Link files in `data/links/` are gitignored and not included in public releases. Clone the full repository to access them.

 **No Additional Runtime Required:**
 - ❌ No .NET Runtime installation needed
 - ❌ No administrator rights required (for normal operations)

 #### What Happened to the C# Version?
 
-The legacy C# WinForms application (v1.0.4.x) has been **archived** to the `_archived/` folder for reference. All functionality has been migrated to the new Flutter + Rust architecture with feature parity and improvements.

 - Requires .NET 9.0 Runtime
 - No longer actively maintained

+**外部下载源（高级功能）：**
+
+varManager 可以从外部源（Pixeldrain、Mediafire）和本地种子文件搜索缺失的 var 包，作为 Hub 的补充：
+
+1. **链接文件设置：**
+   - 在 varManager 目录下创建 `data/links/` 文件夹
+   - 添加包含 var 包链接的 `.txt` 文件（每行一个）
+   - 格式：`VarName.var [空格或制表符] URL`
+   - 示例：`Creator.PackageName.1.var https://pixeldrain.com/u/ABC123`
+
+2. **种子文件设置：**
+   - 创建 `data/links/torrents/` 子文件夹
+   - 放置包含 var 包的 `.torrent` 文件
+   - 扫描器会检测种子元数据中的 var 名称（仅供参考）
+
+3. **预置链接文件：**
+   - 仓库中包含可用的链接文件，位于 `data/links/` 文件夹（已加入 gitignore）
+   - 这些是真实的、经过整理的链接数据库，可直接使用
+   - 文件包含在仓库中，但不包含在公开发布版本中
+
+4. **使用方法：**
+   - 进入缺失 Var 页面
+   - 勾选 "Enable External Sources"（启用外部源）
+   - 选择所需的源（Pixeldrain、Mediafire）
+   - 点击 "Fetch Links (Hub + External)"（获取链接）
+   - Hub 结果始终优先，外部源用于补充
+
+**Torrent Downloads (aria2):**
+- 放置 `aria2c.exe` 到 `data/aria2c.exe`
+- 当没有直链但有 torrent 命中时，使用 aria2 只下载所需 `.var`
+- 下载路径 `varspath\AddonPackages\tmp`，完成后移动到 `varspath`
+- `data/links/torrents/` 下的 `.torrent` 不会被删除
+
+**注意：** `data/links/` 中的链接文件已加入 gitignore，不会包含在公开发布版本中。需要克隆完整仓库才能访问。
