+The MinIO Go Client SDK provides straightforward APIs to access any Amazon S3 compatible object storage.
 
-This quickstart guide will show you how to install the MinIO client SDK, connect to MinIO, and provide a walkthrough for a simple file uploader.
-For a complete list of APIs and examples, please take a look at the [godoc documentation](https://pkg.go.dev/github.com/minio/minio-go/v7) or [Go Client API Reference](https://min.io/docs/minio/linux/developers/go/API.html).

-## Quick Start Example - File Uploader
-This example program connects to an object storage server, creates a bucket and uploads a file to the bucket.
+## Example - File Uploader
 
-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.
+This sample code 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).
+
+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 and all data uploaded to `play` should be considered public and non-protected.
 
 ### FileUploader.go
+
+This example does the following:
+
+- Connects to the MinIO `play` server using the provided credentials.
+- Creates a bucket named `testbucket`.
+- Uploads a file named `testdata` from `/tmp`.
+- Verifies the file was created using `mc ls`.

-### Run FileUploader
+**1. Create a test file containing data:**
+
+You can do this with `dd` on Linux or macOS systems:
+
+```sh
+dd if=/dev/urandom of=/tmp/testdata bs=2048 count=10
+```
+
+or `fsutil` on Windows:
+
+```sh
+fsutil file createnew "C:\Users\<username>\Desktop\sample.txt" 20480
+```
+
+**2. Run FileUploader with the following commands:**
+
 ```sh
-go run file-uploader.go
-2016/08/13 17:03:28 Successfully created mymusic
-2016/08/13 17:03:40 Successfully uploaded golden-oldies.zip of size 16253413

+go get github.com/minio/minio-go/v7/pkg/credentials
+go run FileUploader.go
+```
+
+The output resembles the following:
 
-mc ls play/mymusic/

+
+**3. Verify the Uploaded File With `mc ls`:**
+
+```sh
+mc ls play/testbucket
+[2023-11-01 14:27:55 UTC]  20KiB STANDARD TestDataFile
