+### FastAPI 接口
+
+启动服务后，可使用以下接口：
+
+- `GET /health`：健康检查
+- `GET /nacos/status`：查看 Nacos 注册状态
+- `POST /api/workflows`：执行工作流
+
+示例请求体：
+
+```json
+{
+    "input": "你好，帮我算 1 + 2",
+    "session_id": null,
+    "workflow_type": "conversation"
+}
+```
+
+### Nacos 配置
+
+在 `config/config.ini` 中开启 Nacos：
+
+```ini
+[nacos]
+enabled = true
+server = localhost:8848
+namespace = public
+group_name = DEFAULT_GROUP
+cluster_name = DEFAULT
+heartbeat_interval = 5
+```
+
+### RAGFlow 模板同步
+
+模板文件位于 `config/ragflow_templates`，每个 JSON 对应一个表名与模板列表。
+同步脚本：
+
+```bash
+python scripts/sync_ragflow_templates.py
+```
+
+请在 `config/config.ini` 中配置 `ragflow.upload` 上传接口。
