+We use GitHub Issues as a place to report bugs, request new features, and to
+track the queue of development work. For usage questions, some of our
+repositories use Discussions as an alternative to the <[email protected]>
+mailing list {% include mailing_list_links.html list="user" %}. For those
+repositories, Discussions are mirrored to the <[email protected]> mailing

+ask usage questions in either location. Maintainers may convert usage type
+Issues to Discussions as appropriate.
