+We have a [buildbot](http://buildbot.notmuchmail.org/grid) (here's
+its
+[configuration](https://github.com/tomprince/buildbot-configs/tree/notmuch)).
+
+Contributions, such as patches, to Notmuch are most welcome. Please refer to the
+[[guide to contributing|contributing]].
+
+## Bug and patch tracking
+
+The tagging and filtering features of notmuch make it quite suitable
+for use as a bug- and patch-tracker. We are currently experimenting
+with using it for this purpose for notmuch development, using a
+utility called [[nmbug]]. The status of bugs and current patches can also be
+followed [online](http://nmbug.tethera.net/status).
+
+Bug reports should be sent to the Notmuch mailing list notmuch@notmuchmail.org.
