+- 请去下载对应的源码，并删除此目录最后的波浪线
+- 在项目的 `asmdef` 文件中添加对 `UniTask.YooAsset` 的引用
+- 在 UniTask `_InternalVisibleTo.cs` 文件中增加 `[assembly: InternalsVisibleTo("UniTask.YooAsset")]` 后即可使用
+
+代码示例
+
+```csharp
+var handle = YooAssets.LoadAssetAsync<GameObject>("Assets/Res/Prefabs/TestImg.prefab");
+
+await handle.ToUniTask();
+
+var obj = handle.AssetObject as GameObject;
+var go  = Instantiate(obj, transform);
+
+go.transform.localPosition = Vector3.zero;
+go.transform.localScale    = Vector3.one;
+```
