+### Extension Load Queue
+
+### Purpose
+
+This queue mechanism allows asynchronous loading of extensions by setting a property on the "window" object in the browser. This property has a Symbol data type, which makes it difficult for external manipulations to access it.
+
+### Interface
+
+```typescript
+// create a unique symbol
+export const GLOBAL_SYMBOL: unique symbol = Symbol.for('someController');
+
+// get the store
+const store = getScriptStore<SomeController>(GLOBAL_SYMBOL);
+
+// get the controller
+const controller = useController<SomeController>(store);
 ```
