 ### 配置模型
 本程序支持几种模型来源。其中，本地模型（Local）是基于 Akagi 兼容的 Mortal 模型。要获取 Akagi 的模型，请参见 <a href="https://github.com/shinkuan/Akagi" target="_blank"> Akagi Github </a> 的说明。
+
+#### 使用 Akagi OT2模型 
+如需使用 AkagiOT2 模型，请前往 Akagi 的官方 Discord 频道获取对应的 model.pth 和 riichi3p 包并安装。
+
+第一步：下载模型文件 model.pth 和 riichi3p 包
+
+第二步：将 model.pth 放置到目录 `mjai/bot_3p/` 下
+
+第三步：安装 riichi3p 包
+```bash
+pip install riichi3p-${version}.whl
+```
+此处安装对应 python 版本和操作系统的 riichi3p 包。
+
