-# Introduction
-This directory contains Golang code examples on how to upload an object to an S3 bucket running on a Ceph RGW cluster.
-
-# Prerequisite
-Linux machine running an RGW Ceph cluster. Preferrably started with the ``OSD=1 MON=1 MDS=0 MGR=0 RGW=1 ../src/vstart.sh --debug --new `` command.  
-Go installed on the Linux machine.  
-
-## Workflow Procedure
-1. Install AWS CLI version one on your Linux machine as explained [here](https://docs.aws.amazon.com/cli/v1/userguide/install-linux.html)
-2. Create a bucket on the Ceph cluster with the command 
-```
-aws --endpoint-url http://localhost:8000 s3 mb s3://sample-bucket
-```
-3. Navigate through your file system to where the Go example code is using your terminal.
-4. Run ``` go mod tidy ``` to install the required Go packages on the system.
-5. Run the Go program as ``` go run object-upload.go sample-bucket fortuna.txt ``` on the terminal window to test out object upload to Ceph RGW cluster.
