 # AstrBot 管理面板
 
-基于 CodedThemes/Berry 模板开发。
\ No newline at end of file
+基于 CodedThemes/Berry 模板开发。
+
+## 环境变量
+
+- `VITE_ASTRBOT_RELEASE_BASE_URL`（可选）
+  - 默认值：`https://github.com/AstrBotDevs/AstrBot/releases`
+  - 用途：管理面板内“更新到最新版本”外部跳转所使用的 release 基地址。集成方可按需覆盖（例如 Desktop 指向其自身发布页）。
+  - 建议传入仓库的 `.../releases` 基地址（不带 `/latest`）。
