+## Use Queues for Concurrent Workflows
+
+Queues run many workflows concurrently with managed flow control. Use them when you need to control how many workflows run at once.
+
+**Incorrect (uncontrolled concurrency):**
+
+```go
+// Starting many workflows without control - could overwhelm resources
+for _, task := range tasks {
+	dbos.RunWorkflow(ctx, processTask, task)
+}
+```
+
+**Correct (using a queue):**
+
+```go
+// Create queue before Launch()
+queue := dbos.NewWorkflowQueue(ctx, "task_queue")
+
+func processAllTasks(ctx dbos.DBOSContext, tasks []string) ([]string, error) {
+	var handles []dbos.WorkflowHandle[string]
+	for _, task := range tasks {
+		handle, err := dbos.RunWorkflow(ctx, processTask, task,
+			dbos.WithQueue(queue.Name),
+		)
+		if err != nil {
+			return nil, err
+		}
+		handles = append(handles, handle)
+	}
+	// Wait for all tasks
+	var results []string
+	for _, h := range handles {
+		result, err := h.GetResult()
+		if err != nil {
+			return nil, err
+		}
+		results = append(results, result)
+	}
+	return results, nil
+}
+```
+
+Queues process workflows in FIFO order. All queues must be created with `dbos.NewWorkflowQueue` before `Launch()`.
