+### 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。
 
-[直达通道(传家宝套餐)](https://bwh88.net/aff.php?aff=117&pid=147)
+> **🔔 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。
 
-&nbsp;
+### 第二步：部署插件
 
-## 功能介绍
+#### 🔹 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。
 
+#### 🔹 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：
 
-- [x] 支持  迅雷看看    字幕下载    Hash匹配
-- [x] 支持  射手影音    字幕下载    Hash匹配
+- **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

+<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>
 
+<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>
 
+<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>
 
-## 使用插件
+<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>
 
-首先下载已编译好的插件 [LINK](https://github.com/91270/Emby.MeiamSub/releases) ，由于 Jellyfin 自身 [BUG](https://github.com/jellyfin/jellyfin/issues/12434) , 会重复下载字幕 。
+---
 
-建议：媒体库不勾选本插件, 自动扫描缺失字幕时不使用该插件，但不影响手动查找字幕
