+# 0. Repository Clone Instructions (Git LFS)
+
+The robotic hand STL model files (`.STL`) in this repository are hosted via Git LFS (Large File Storage). A plain `git clone` will only fetch pointer placeholder files, and the MuJoCo simulation will fail because it cannot find the STL models.
+
+**Install Git LFS before cloning:**
+```bash
+sudo apt install git-lfs
+git lfs install
+```
+
+**Then clone the repository:**
+```bash
+git clone https://gitea.robotquan.com/chenshijue/delay-measurement.git
+```
+
+After cloning, the STL files will be automatically downloaded as full content via LFS.
+
+**Verify LFS files were fetched (optional):**
+```bash
+git lfs ls-files        # should list all *.STL files
+```

+# 0. 仓库克隆说明（Git LFS）
+
+本仓库中的机械手 STL 模型文件（`.STL`）使用 Git LFS（Large File Storage）托管。直接 `git clone` 只会拉取到指针占位文件，MuJoCo 仿真会因找不到 STL 而报错。
+
+**克隆前请先安装 Git LFS：**
+```bash
+sudo apt install git-lfs
+git lfs install
+```
+
+**然后克隆仓库：**
+```bash
+git clone https://gitea.robotquan.com/chenshijue/delay-measurement.git
+```
+
+克隆完成后，STL 文件会自动通过 LFS 下载为完整内容。
+
+**验证 LFS 是否拉取成功（可选）：**
+```bash
+git lfs ls-files        # 应列出所有 *.STL 文件
+```
