+## Rate Limiting
+
+If you want to move a job back to wait because your queue is rate limited.
+
+```typescript
+const worker = new Worker('my-queue', null, { connection, prefix });
+const token = 'my-token';
+await Job.create(queue, 'test', { foo: 'bar' });
+const job = (await worker.getNextJob(token)) as Job;
+
+await queue.rateLimit(60000);
+await job.moveToWait(token);
+```
