+These are some helpful resources to use lemmy on FreeBSD, including rc scripts and syslog/newsyslog configurations.
+
+Also, if after running lemmy the first time, it dies due to being unable to run migrations requiring system trigger,
+run `sql/run_migrations.sql` against your DB and try to start it again..
+
+Someday maybe I will make a port.
