 **PlayEdu** 是基于 Java + SpringBoot3.0 开发的开源的企业、机构、大学院校的内部培训解决方案。
 
+### 开始上手
+
+使用 `docker` 安装 `minio` :
+
+> 下面是测试环境安装的 minio .
+
+```
+docker run -p 9000:9000 -p 50000:50000 -d --name playedu-minio \
+  -e "MINIO_ACCESS_KEY=username" \
+  -e "MINIO_SECRET_KEY=password" \
+  minio/minio server --console-address ":50000" /data
+```
+
+如果您想在生产环境中使用，推荐您做好数据卷的挂载并自行配置 `AccessKey` 和 `SecretKey` :
+
+```
+docker run -p 9000:9000 -p 50000:50000 -d --name playedu-minio \
+  -e "MINIO_ACCESS_KEY=自定义用户名" \
+  -e "MINIO_SECRET_KEY=自定义密码" \
+  -v /mnt/data:/data \
+  -v /mnt/config:/root/.minio \
+  minio/minio server --console-address ":50000" /data
+```
