 Contributions are welcome (of course!); we require a simple one-page CLA to help simplify distribution
 (corporate users want to know how contributions are handled), one per contributor. Feel free to submit
 Pull Requests and we will get you through this formality.
 
+One special case is that for reporting possible security issues ("vulnerabilities"), we recommend filing a
+[Tidelift security contact](https://tidelift.com/security) (NOTE: you do NOT have to be a subscriber to do this).
