Missing step to setup virtual env in CONTRIBUTING.md

Is your feature request related to a problem?

As a new comer I was setting up development environment on my local machine following the instructions CONTRIBUTING.md.

The instructions were difficult to follow due to the sequence of the steps. Some steps are missing while some need more explanation.
Respective commands to run on a Windows environment are missing as well.

Attached file where I've tried to rewrite the steps to setup dev environment while checking the sequence of commands on my local machine too.
Please leave your feedback and suggestions for further improvements.

Describe the solution you'd like

I'd like to rewrite CONTRIBUTION.md in sequential order to make it clear so new comers don't have difficulty going through the steps.
