## Quick Start Example - File Uploader
This example program connects to an object storage server, creates a bucket and uploads a file to the bucket.
We will use the Minio server running at [https://play.minio.io:9000](https://play.minio.io:9000) in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.

### PutObject(bucketName, objectName string, reader io.Reader, contentType string) (n int, err error)
Uploads an object.
Uploads objects that are less than 64MiB in a single PUT operation. For objects that are greater than 64MiB in size, PutObject seamlessly uploads the object as parts of 64MiB or more depending on the actual file size. The max upload size for an object is 5TB.

### PutObjectStreaming(bucketName, objectName string, reader io.Reader) (n int, err error)
Uploads an object as multiple chunks keeping memory consumption constant. It is similar to PutObject in how objects are broken into multiple parts. Each part in turn is transferred as multiple chunks with constant memory usage. However resuming previously failed uploads from where it was left is not supported.
