Define contribution guidelines and license

[mouss3abbb]

I suggest adding CONTRIBUTION and LICENSE files.
The contribution files should explain the approach to adding to the repo and can be more in-detail explanation for beginners
The license is necessary to any open sources project.

I can handle them if assigned

Yeah sure, great idea. You can start working on it.
