+## Quickstart
+```shell
+#构建docker镜像
+docker build . -t metax_c500_vl
+
+#运行docker容器
+docker run -it -p 10055:8000 --device=/dev/mxcd --device=/dev/dri -v /home/aiyueqi/mnt/models/vlm/MiniCPM-V-4:/model:ro --name metax_c500_vl_test metax_c500_vl
+```
+等待模型Load完成，出现以下日志时，代表服务启动成功, 且模型加载完成
+```shell
+INFO:     Application startup complete.
+INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
+```
+执行测试程序
+```shell
+python3 test.py
+```
+测试程序执行结果
+```
+Succeed!
+Response: {'output_text': '这幅图片包含几个元素，共同营造出宁静的氛围。主要对象是一个坐在沙滩上的金毛寻回犬和一个穿着格子衬衫的人。狗似乎正与这个人互动，可能是在玩耍或训练，因为它的爪子和人的手在接触。狗戴着颜色鲜艳的项圈，表明它可能接受过训练或习惯于与人互动。这个人看起来很放松，微笑着，暗示着他们之间的亲密关系。背景是一片宁静的海滩，太阳低垂在地平线上，为场景投射出温暖的金色光线。这可能是一天中的早晨或傍晚，因为光线柔和而扩散。海滩上没有其他人，强调了两个人之间的个人时刻。这张图片唤起了和平、陪伴和简单之美的感觉。'}
+```
+停止docker容器
+```
+docker stop metax_c500_translation_test
+```
+## 模型支持
+在Quickstart中运行容器时，通过磁盘目录挂载的方式，指定模型的类型和具体的模型名称，即：
+```
+-v /home/aiyueqi/mnt/models/vlm/MiniCPM-V-4:/model:ro
+```
+目前支持MiniCPM模型, 参考https://modelscope.cn/models/OpenBMB/MiniCPM-V-4
