CONTRIBUTING.md

+# Contributing to Zstandard
+We want to make contributing to this project as easy and transparent as
+possible.
+
+## Our Development Process
+New versions are being developed in the "dev" branch,
+or in their own feature branch.
+When they are deemed ready for a release, they are merged into "master".
+
+As a consequences, all contributions must stage first through "dev"
+or their own feature branch.
+
+## Pull Requests
+We actively welcome your pull requests.
+
+1. Fork the repo and create your branch from `dev`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation.
+4. Ensure the test suite passes.
+5. Make sure your code lints.
+6. If you haven't already, complete the Contributor License Agreement ("CLA").
+
+## Contributor License Agreement ("CLA")
+In order to accept your pull request, we need you to submit a CLA. You only need
+to do this once to work on any of Facebook's open source projects.

+We use GitHub issues to track public bugs. Please ensure your description is
+clear and has sufficient instructions to be able to reproduce the issue.
+
+Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe
+disclosure of security bugs. In those cases, please go through the process
