 ## Config
 
 You need to configure the environment variables as follows:
-- `MINIO_URL`: s3 service address
+- `MINIO_URL`: s3 service address, `<hostname>:<port>`, for example: `example.com:443`, not need protocol part like `https://`
 - `MINIO_SSL`: Whether the s3 service enables SSL verification is required for some providers. Default is `false`
 - `MINIO_USER`: s3 service username
 - `MINIO_PASS`: s3 service password
 - `MINIO_BUCKET_NAME`: s3 service bucket name
 - `MINIO_PATH_STYLE`: path mode, optional values: `VirtualHosted` or `Path`
+  - S3 protocol has two style, `VirtualHosted` use in `<bucketname>.example.com`, and `Path` use in `example.com/<bucketname>`
 - `STATIC_URL`: The uploaded static path address, which is transferred by the server by default. If you want to directly connect to external storage, you need to change it to an externally accessible address

 - `MINIO_PASS`: s3服务密码
 - `MINIO_BUCKET_NAME`: s3服务 bucket 名
 - `MINIO_PATH_STYLE`: 路径模式，可选值: `VirtualHosted` 或 `Path`
+  - S3 协议有两种风格，`VirtualHosted` 用于 `<bucketname>.example.com`，`Path` 用于 `example.com/<bucketname>`
 - `STATIC_URL`: 上传后的静态路径地址，默认走服务器中转，如果想要走外部存储直连的话需要改为外部可访问的地址
