Following example shows connecting via sftp client using `minioadmin` credentials, and list a bucket named `runner`:

```
sftp -P 8022 minioadmin@localhost
minioadmin@localhost's password:
Connected to localhost.
sftp> ls runner/
chunkdocs  testdir
```

Following example shows how to download an object locally via `sftp` client:

```
sftp> get runner/chunkdocs/metadata metadata
