-# ShrinkSDK Installer

-`com.cneicy.shrink-installer` is the Git URL bootstrap package for ShrinkSDK.
+`com.cneicy.shrink-installer` 是 ShrinkSDK 的固定版本引导包。通过不可变 Git 标签安装后，在 Unity 中打开 `ShrinkSDK/包管理`。
 
-Install the package from an immutable tag, then open `ShrinkSDK/Packages` in the Unity editor. The window merges the public ShrinkSDK scoped registry without replacing other registries and writes only catalogue-pinned dependencies to `Packages/manifest.json`. Packages which require UniTask also receive its fixed Git revision.
+窗口使用 UI Toolkit 构建，提供：
 
-The installer does not copy templates into `Assets`, does not store credentials, and does not add an unpinned package version.
+- 当前项目直接与间接依赖的真实安装状态；
+- 已安装版本与目录固定版本的对比；
+- 以 `Context` 组合基础、应用与组合根、独立功能、模块集成、编译工具为层级的全部包列表；
+- 基础应用、Context 最小基座、Context 应用宿主、事件与命令、存档、网络、模组开发、常用完整套件八种组合；
+- 保留既有 scoped registry 的安全合并，以及固定版本安装或版本切换。
 
-## Bootstrap URL
+安装器只修改 `Packages/manifest.json` 的 registry 与依赖数据，不写认证信息，不复制模板到 `Assets`，也不添加浮动版本。需要 UniTask 的安装入口会同时固定到目录指定的 Git revision。
