- fan-out/fan-in, loops, retry, state management, dynamic nodes,
- human-in-the-loop, and nested workflows.
+- **Workflow Runtime（工作流运行时）**：基于图的执行引擎，用于为智能体应用编排确定性执行流程，支持路由、扇出/扇入（fan-out/fan-in）、循环、重试、状态管理、动态节点、人机协同（human-in-the-loop）以及嵌套工作流。
-- **Task API**: Structured agent-to-agent delegation with multi-turn task
- mode, single-turn controlled output, mixed delegation patterns,
- human-in-the-loop, and task agents as workflow nodes.
+- **Task API（任务 API）**：结构化的智能体间委托，支持多轮任务模式、单轮受控输出、混合委托模式、人机协同，以及将任务智能体作为工作流节点。

-## Quick Start
+## 快速开始
-> **Beginner Note:** ADK applications are built using two main classes:
-> **`Agent`** (defines an AI's instructions, tools, and behavior) and
-> **`Workflow`** (orchestrates agents and tasks in a graph-based flow).
