suggestion to add contributing doc in Readme

[malingyan2017]

Hi,
I noticed that in the readme file, there is no contributing guide or authors' contact information.
although that information is presented in your website, I feel that it might be beneficial to have the how to contribute guide in the readme file, since it is the very first place people would look at when they open the page in Github.
Thank you!

What should this document say? From the perspective of a potential contributor, what information is missing?

I have created a first draft of the Contribution Guidelines here: #2675

Please let me know if there are any changes that need to be made so I can update it appropriately
