+
+### To create the group
+In ~/.gnupg/gpg.conf:
+```
+auto-key-retrieve

+group engineers = fdamstra@keybase.io Brad Duane
+#group salt = fdamstra@keybase.io Brad Duane mdr-engineering@defpoint.com mdr.eng@accenturefederal.com
+group salt = fdamstra@keybase.io Brad Duane mdr-engineering@defpoint.com
