+### Moving Discussions and Questions to GitHub Discussions
+
+For issues labeled with `question` or `discuss`, it is recommended to move them to GitHub Discussions instead:
+
+* **Questions**: User questions that do not appear to be bugs or enhancements should be moved to GitHub Discussions.
+* **Discussions**: Topics for discussion should be moved to GitHub Discussions. If the discussion leads to a new feature or bug identification, it can be moved back to Issues.

 In all cases, issues may be closed by maintainers if they don't receive a timely response when
 further information is sought, or when additional questions are asked.
