New Contributing Guideline


Dear Community:
As we improve the codebase we feel that it is important to document the lessons, so that they can serve as guidelines for the future contributors and reviewers. We did an upgrade of the contributor guidelines and they
can be found here:
As a community, we need your help in improving this, sharing your lessons and make the contribution process as fun as possible. Please take some time to read the new docs and post your thoughts here. Even better, please send pull requests to include new tips and lessons we learnt through the review process


Add section about testing(c++, python, etc)? Like how to run unit tests locally.


+1, can you send a PR?


OK, will do it later.
