 ### 运行已有品牌
 
+建议优先使用仓库内 `.fvm` 的 Flutter / Dart，避免全局版本不一致。
+
+Windows PowerShell：
+
+```powershell
+cd apps/aixue
+..\..\.fvm\flutter_sdk\bin\flutter.bat run
+```
+
+macOS / zsh：
+
 ```bash
 cd apps/aixue
-flutter run
+../../.fvm/flutter_sdk/bin/flutter run
 ```
 
 也可以替换为：
 
-```bash
+```powershell
 cd apps/test
-flutter run
+..\..\.fvm\flutter_sdk\bin\flutter.bat run
 ```
 
 ```bash
 cd apps/yunxiao
-flutter run
+../../.fvm/flutter_sdk/bin/flutter run
 ```
 
 ### 生成或重建品牌应用
 
-```bash
-dart run tool/generate_app.dart aixue
-dart run tool/generate_app.dart test
-dart run tool/generate_app.dart yunxiao
+请在仓库根目录执行。
+
+Windows PowerShell：
+
+```powershell
+.\.fvm\flutter_sdk\bin\dart.bat run tool\generate_app.dart aixue
+.\.fvm\flutter_sdk\bin\dart.bat run tool\generate_app.dart test
+.\.fvm\flutter_sdk\bin\dart.bat run tool\generate_app.dart yunxiao
 ```
 
+macOS / zsh：
+
+```bash
+./.fvm/flutter_sdk/bin/dart run tool/generate_app.dart aixue
+./.fvm/flutter_sdk/bin/dart run tool/generate_app.dart test
+./.fvm/flutter_sdk/bin/dart run tool/generate_app.dart yunxiao
+```
+
+注意：生成脚本会删除并重建已有的 `apps/<品牌名>/` 目录。
+
 生成脚本会自动完成：
 
 - 创建 Flutter Android 应用到 `apps/<品牌名>/`
