+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

-## 🚀 快速安装
+## 安装
 
-### 第一步：获取插件
-前往 [GitHub Releases](https://github.com/91270/Emby.MeiamSub/releases) 下载最新版本的发布包。
+### Jellyfin 存储库
 
-> **🔔 推荐建议**：在媒体库设置中**不勾选**本插件作为默认自动下载器。建议仅在手动“搜索字幕”时使用，以获得更精准的人工筛选体验。
+推荐通过插件存储库安装，以便接收后续更新。
 
-### 第二步：部署插件
+1. 打开 Jellyfin 控制台的“插件 → 存储库”。
+2. 添加存储库名称 `MeiamSub`。
+3. 填写以下地址：
 
-#### 🔹 方式 A：Jellyfin 存储库安装 (强烈推荐)
-Jellyfin 用户可直接添加官方存储库，实现一键安装与自动更新：
-1. 控制台 -> **插件** -> **存储库** -> 点击“添加”。
-2. 输入名称 `MeiamSub` 和 URL：  
-   `https://github.com/91270/MeiamSubtitles.Release/raw/main/Plugin/manifest-stable.json`
-3. 在“目录”中找到插件并安装，重启服务即可。
+   ```text
+   https://github.com/91270/MeiamSubtitles.Release/raw/main/Plugin/manifest-stable.json
+   ```
 
-#### 🔹 方式 B：手动安装 (Emby/通用)
-将下载的 `.dll` 文件（Jellyfin 用户请下载 `.zip` 并解压完整目录）放入服务器的 `plugins` 文件夹：
+4. 在“目录”中分别安装 `MeiamSub.Assrt` 或 `MeiamSub.Thunder`。
+5. 重启 Jellyfin。
 
-- **Windows**: `AppData\Local\jellyfin\plugins` 或 `Emby-Server\programdata\plugins`
-- **Linux/Docker**: `/config/plugins` 或 `/var/lib/emby/plugins`
-- **群晖/威联通**: 对应套件安装目录下的 `plugins` 文件夹

-## ❓ 常见问题排查 (FAQ)
+#### Emby
 
-<details>
-<summary><b>1. 为什么在 Jellyfin 10.11+ 中搜不到字幕？</b></summary>
-新版 Jellyfin 采用了三位字母的语言代码（如 <code>zho</code>）。请确保您已升级至本插件的 <b>v1.0.13.0</b> 或更高版本，该版本已完美解决语言映射兼容性。
-</details>
+1. 解压 `Emby_v*.zip`。
+2. 将需要的插件 DLL 放入 Emby 的 `plugins` 目录。
+3. 不要额外复制 `SharpCompress.dll`；Assrt 复用 Emby 自带版本。
+4. 重启 Emby。
 
-<details>
-<summary><b>2. 为什么射手网有时候返回结果为空？</b></summary>
-由于射手网 API 维护状态不佳，对于部分冷门资源或 Hash 不匹配的文件，API 可能会返回非法数据。插件目前已增加防御逻辑，会自动忽略这些无效返回以保护服务器稳定。
-</details>
+#### Jellyfin
 
-<details>
-<summary><b>3. 安装本插件后会影响 Open Subtitles 吗？</b></summary>
-不会。本插件已将优先级 (Order) 调整为 100（低优先级），并在代码层面优化了并发逻辑，确保官方插件能优先获取请求机会。
-</details>
+1. 解压 `Jellyfin_v*.zip`。
+2. 将需要的整个插件目录复制到 Jellyfin 的 `plugins` 目录。
+3. Assrt 目录中的 `SharpCompress.dll` 是 Jellyfin 所需依赖，请勿单独删除。
+4. 重启 Jellyfin。
 
-<details>
-<summary><b>4. 如何提供有效的错误反馈？</b></summary>
-如果确定有字幕但搜不到，请在 Issue 中提供日志里的 <code>Target</code> 文件名、计算出的 <code>FileHash</code> 以及 <code>ResponseBody</code> 内容。
-</details>
+### 从旧版本升级
 
----
+- 升级到 v1.0.16.0 或更高版本后，删除旧的 Shooter DLL 和插件目录；Shooter 已停止维护和发布。
+- 同一个插件不要同时保留多个版本，否则服务器可能重复加载或启动失败。
+- Emby Assrt 只需保留插件 DLL，不要额外复制 `SharpCompress.dll`。

+## 配置
 
----
+### Assrt
 
-## ⭐️ 给个星星
+1. 从 [Assrt](https://assrt.net/) 获取 API Token。
+2. 打开插件配置页，将 Token 填入 `Assrt API Token`。
+3. 在媒体库的字幕下载器中启用 `MeiamSub.Assrt`。
 
-如果你喜欢这个项目，请给一个 **Star**！这对我非常重要。
+未配置 Token 时，Assrt 会跳过搜索并在日志中给出提示。
 
-如果你有稳定的 Google Drive 团队盘资源可供媒体库插件测试，欢迎联系：`91270#QQ.COM`
+### Thunder
 
----
-*Powered by Meiam*
+Thunder 默认使用视频文件计算 CID。Jellyfin 版本还可在插件设置中启用元数据搜索，用影片名称辅助匹配。
+
+## 自动下载说明
+
+建议先通过“搜索字幕”手动确认匹配效果，再决定是否启用媒体库自动下载。
+
+- 同一媒体库的字幕下载语言只应添加一次。例如只保留一个 `zho`，重复添加会让服务器发起多次下载请求。
+- Emby 与 Jellyfin 如果共用媒体目录，会采用不同的字幕文件命名方式，因此目录中可能同时出现 `.zh-CN.*` 和 `.zho.*` 文件。
+- `SearchAllProviders` 表示同时搜索多个字幕源，不代表下载全部搜索结果。
+- 自动下载行为由 Emby/Jellyfin 调度；插件只响应服务器发出的搜索与下载请求。
+
+## 常见问题
+
+### 搜不到字幕
+
+- 确认字幕语言已选择中文，并使用最新版插件。
+- Assrt 用户请确认 Token 已填写且有效。
+- Thunder 依赖视频文件内容计算 CID，请确认服务器能够读取媒体文件。
+- 某些影片或版本可能没有对应资源，可尝试启用元数据搜索或手动选择其他结果。
+
+### 自动生成了多个字幕文件
+
+首先检查媒体库的“字幕下载语言”是否存在重复项。服务器会为每个语言项分别执行一次下载，产生 `.0`、`.1` 等后缀。
+
+手动连续下载不同的搜索结果时，服务器也会为避免覆盖已有字幕而添加数字后缀。这属于 Emby/Jellyfin 的文件保存行为，不表示插件正在循环下载。
+
+### Assrt 提示找不到 SharpCompress
+
+- Emby：仅安装插件 DLL，不要携带其他版本的 `SharpCompress.dll`。
+- Jellyfin：确保 Assrt 插件目录中包含发布包附带的 `SharpCompress.dll`。
+
+### 如何反馈问题
+
+请在 [Issues](https://github.com/91270/MeiamSubtitles/issues) 中提供：
+
+- Emby/Jellyfin 版本与操作系统；
+- 插件名称和版本；
+- 媒体文件名、容器格式及问题复现步骤；
+- 对应时间段的服务器日志。
+
+提交日志前请删除 Token、媒体路径和其他隐私信息。
