+# Work Scheduler
+
+The **workScheduler** module provides the APIs for registering, canceling, and querying Work Scheduler tasks, which do not have real-time constraints.
+
+The system executes Work Scheduler tasks at an appropriate time, subject to the storage space, power consumption, temperature, and more.
+
+>  **NOTE**
+>
+>  - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+>  - The APIs of this module can be used only in the stage model.
+>  - For details about the restrictions, see [Restrictions on Using Work Scheduler Tasks](../../task-management/background-task-overview.md#restrictions-on-using-work-scheduler-tasks).
+
+
+## Modules to Import
+
+```js
+import workScheduler from '@ohos.resourceschedule.workScheduler';
