+
+## Enqueue Workflows from External Applications
+
+Use `client.Enqueue()` to submit workflows from outside your DBOS application. Since the Client runs externally, workflow and queue metadata must be specified explicitly by name.
+
+**Incorrect (trying to use RunWorkflow from external code):**
+
+```go
+// RunWorkflow requires a full DBOS context with registered workflows
+dbos.RunWorkflow(ctx, processTask, "data", dbos.WithQueue("myQueue"))
+```
+
+**Correct (using Client.Enqueue):**
+
+```go
+client, err := dbos.NewClient(context.Background(), dbos.ClientConfig{
+	DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
+})
+if err != nil {
+	log.Fatal(err)
+}
+defer client.Shutdown(10 * time.Second)
+
+// Basic enqueue - specify workflow and queue by name
+handle, err := client.Enqueue("task_queue", "processTask", "task-data")
+if err != nil {
+	log.Fatal(err)
+}
+
+// Wait for the result
+result, err := handle.GetResult()
+```
+
+**Enqueue with options:**
+
+```go
+handle, err := client.Enqueue("task_queue", "processTask", "task-data",
+	dbos.WithEnqueueWorkflowID("custom-id"),
+	dbos.WithEnqueueDeduplicationID("unique-id"),
+	dbos.WithEnqueuePriority(10),
+	dbos.WithEnqueueTimeout(5*time.Minute),
+	dbos.WithEnqueueQueuePartitionKey("user-123"),
+	dbos.WithEnqueueApplicationVersion("2.0.0"),
+)
+```
+
+Enqueue options:
+- `WithEnqueueWorkflowID`: Custom workflow ID
+- `WithEnqueueDeduplicationID`: Prevent duplicate enqueues
+- `WithEnqueuePriority`: Queue priority (lower = higher priority)
+- `WithEnqueueTimeout`: Workflow timeout
+- `WithEnqueueQueuePartitionKey`: Partition key for partitioned queues
+- `WithEnqueueApplicationVersion`: Override application version
+
+The workflow name must match the registered name or custom name set with `WithWorkflowName` during registration.
+
+Always call `client.Shutdown()` when done.
