+# effector/require-pickup-in-persist
+
+Requires every `persist` call of the [`effector-storage`](https://github.com/yumauri/effector-storage) library to include a `pickup` event when using [`Scope`s](https://effector.dev/api/effector/scope/). This ensures the correct initial value is loaded into the store for each `Scope`.
+
+```ts
+import { persist } from "effector-storage/query";
+
+const $store = createStore("example");
+
+// 👎 no pickup, does not work with Scope
+persist({ store: $store });
+```
+
+```ts
+const pickup = createEvent();
+
+// 👍 pickup is specified
+persist({ store: $store, pickup });
+```
