First public release

**Note:**  this is new pull request against empty develop branch. I'm removing previos pull request.

Team,

I appreciate if you can review the thing I am putting.

I undertand it's kind of big, but any feedback appreciated: documentation, policy writing etc.

Happy to answer any questions.
