 ## Quick Start Example - File Uploader
 
-This example program connects to an object storage server, makes a bucket on the server and then uploads a file to the bucket.
+This example connects to an object storage server, creates a bucket, and uploads a file to the bucket.
+It uses the MinIO `play` server, a public MinIO cluster located at [https://play.min.io](https://play.min.io).
 
-We will use the MinIO server running at [https://play.min.io](https://play.min.io) in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.
+The `play` server runs the latest stable version of MinIO and may be used for testing and development.
+The access credentials shown in this example are open to the public.
+All data uploaded to `play` should be considered public and non-protected.
