 5. **安装 7-Zip**
     - 从 https://7-zip.org/ 下载并安装
-    - 使用默认安装路径安装:
-      * 64位系统: C:\Program Files\7-Zip
-      * 32位系统: C:\Program Files (x86)\7-Zip
-    - 脚本会自动检测这些路径
+    - 将7-Zip安装目录添加到系统PATH:
+      1. 打开"系统属性" > "环境变量"
+      2. 在"系统变量"中找到"Path"
+      3. 点击"编辑" > "新建"
+      4. 添加7-Zip安装目录(默认为C:\Program Files\7-Zip)
+      5. 点击"确定"保存
+    - 重启终端使PATH生效
 
 6. **下载预训练模型和资源**
     ```cmd
+    git clone https://github.com/Jeffreytsai1004/GaussianHairCut
+    cd GaussianHairCut
     # 在PowerShell中运行:
     # 脚本会自动安装gdown并下载所需资源
