+#### 二、编译并安装  `InfiniLM`
+  - 克隆项目
   
+    由于仓库中含有子模块，所以在克隆时请添加 `--recursive` 或 `--recurse-submodules`，如：
 
-- 编译并安装 `InfiniLM` Python 包
-  - 安装第三方依赖
-  ```bash
+    ```shell
+    git clone --recursive https://github.com/InfiniTensor/InfiniCore.git
+    ```
+
+    或者在普通克隆后进行更新：
+
+    ```shell
     git submodule update --init --recursive
     ```
 
+
   - 安装 InfiniLM Python 包
     ```bash
       pip install -e .
     ```
