 这是一个 **monorepo**。它的组织方式本身就表达了一条原则:**`spec/` 是上游的语义母本,其余部件是向它对齐的实现。**
 
+## 安装 `cph` 命令行
+
+当前版本 **0.0.1**。从源码安装(本仓库根目录):
+
+```sh
+cargo install --path crates/cph-cli --locked
+```
+
+`render` 包已嵌入二进制(build.rs 编译期拷入 + `include_dir!`),所以装好后**无需任何环境变量、不依赖源码树**即可用。渲染包按版本解压到 per-user cache(`~/.cache/cph/render-<version>/` 或 macOS `~/Library/Caches/cph/...`);开发时可设 `CPH_RENDER_DIR` 指向 live `render/` 目录覆盖。
+
+```sh
+cph --version          # cph 0.0.1
+cph check <工程目录>     # 校验合法性(6 类诊断)
+cph build <工程目录> --target student -o build/student.pdf   # 渲讲义 PDF
+```
+
