+## Bug-tracking and patches
+
+Patches are most welcome and should be sent to notmuch@notmuchmail.org.
+Please try to follow the [[patch submission guidelines|patchformatting]]
+when submitting patches.
+
+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 current patches can also be
+followed [online](http://nmbug.tethera.net/status).
