+[Docker Engine](https://docs.docker.com/engine/install/ubuntu/) first. Your user
+must be able to run `docker` commands; use `sudo docker` if required. Run the
+following example based on the
+[RustFS Docker guide](https://docs.rustfs.com/en/installation/container/docker):
 
 ```bash
-cd $HOME
-mkdir minio-service && cd minio-service
-wget https://dl.min.io/server/minio/release/linux-amd64/minio

-By default, `minio` listens on `http://127.0.0.1:9000`, whose default credentials is `minioadmin:minioadmin`,.
+This example exposes the S3 API at `http://127.0.0.1:9000` and uses
+`rustfsadmin:rustfsadmin` for local testing, matching the CI credentials.
 
 **Step-5**, go back to the package directory and start the server. The shipped
-configs already point at the local minio and use paths relative to the package
-directory, so no editing is needed to try it out:
