+s3-benchmark is a performance testing tool provided by Wasabi for performing S3 operations (PUT, GET, and DELETE) for objects. Besides the bucket configuration, the object size and number of threads varied be given for different tests.
+
+The testing tool is loosely based on the Nasuni (http://www6.nasuni.com/rs/nasuni/images/Nasuni-2015-State-of-Cloud-Storage-Report.pdf) performance benchmarking methodologies used to test the performance of different cloud storage providers
+
+# Prerequisites
+To leverage this tool, the following prerequisites apply
+•	Git development environment
+•	Ubuntu Linux shell programming skills
+•	Access to a Go 1.7 development system (only if the OS is not Ubuntu Linux 16.04)
+•	Access to the appropriate AWS EC2 (or equivalent) compute resource (optimal performance is realized using m4.10xlarge EC2 Ubuntu with 10 GB ENA)
 
-The test is loosely based on the Nasuni benchmark used to test the performance of different cloud
-storage providers.
 
 # Building the Program
-Obtain a local copy of the repository using the following git command:
+Obtain a local copy of the repository using the following git command with any directory that is convenient:
 
 ```
 git clone https://github.com/wasabi-tech/s3-benchmark.git
 ```
 
+You should see the following files in the s3-benchmark directory.
+LICENSE	README.md		s3-benchmark.go	s3-benchmark.ubuntu
+
 If the test is being run on Ubuntu version 16.04 LTS (the current long term release), the binary
-executable s3-benchmark.ubuntu will run the benchmark without building. 
+executable s3-benchmark.ubuntu will run the benchmark testing without having to build the executable. 
 
-Otherwise, to build the test, you must install Go 1.7 development system along with the supporting libraries
-given in the import section.
+Otherwise, to build the s3-benchmark executable, you must issue this following command:
+/usr/bin/go build s3-bechmark.go

 # Note
-Your benchmark results may vary most often because of limitations of your network connection to the cloud storage
-provider.  Wasabi performance claims are tested under conditions that remove any latency (which can be shown using 
-the ping command) and bandwidth bottlenecks that restrict how fast data can be moved.  For more information,
