+## Quickstart
+
+### 构建镜像
+```bash
+docker build -t text2video:v0.1 .
+```
+
+### 模型下载
+模型地址：https://modelscope.cn/models/iic/text-to-video-synthesis
+并放到目录：`/mnt/contest_ceph/zhanghao/models/iic/text-to-video-synthesis`（如更改目录，请修改后面的执行脚本中的模型路径）
+
+### 测试程序
+1. 准备输入数据集，可以参考示例`dataset.json`
+2. 在docker镜像里运行测试程序，会根据`dataset.json`内容，在`output`目录下生成视频文件。
+```bash
+python3 main.py --model "/mnt/contest_ceph/zhanghao/models/iic/text-to-video-synthesis" --json  "dataset.json" --results "results.json" --outdir "output" --device cuda --dtype fp16
+```
+
+## 测试结果
+|      | A100 平均生成时间（秒） | MetaX C500 平均生成时间（秒） |
+|------|-------------------------|----------------------------|
+| 时间 | 12                  | 16                     |
