+If you want to connect to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). Just assign empty string to the first two parameters of `NewSyslogHook`. It should look like the following.
+
+```go
+import (
+  "log/syslog"
+  "github.com/Sirupsen/logrus"
+  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
+)
+
+func main() {
+  log       := logrus.New()
+  hook, err := logrus_syslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
+
+  if err == nil {
+    log.Hooks.Add(hook)
+  }
+}
+```
