-# Syslog Hooks for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>
-
-## Usage
-
-```go
-import (
-  "log/syslog"
-  "github.com/sirupsen/logrus"
-  lSyslog "github.com/sirupsen/logrus/hooks/syslog"
-)
-
-func main() {
-  log       := logrus.New()
-  hook, err := lSyslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
-
-  if err == nil {
-    log.Hooks.Add(hook)
-  }
-}
-```
-
-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"
-  lSyslog "github.com/sirupsen/logrus/hooks/syslog"
-)
-
-func main() {
-  log       := logrus.New()
-  hook, err := lSyslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
-
-  if err == nil {
-    log.Hooks.Add(hook)
-  }
-}
-```
-
-### Different log levels for local and remote logging
-
-By default `NewSyslogHook()` sends logs through the hook for all log levels. If you want to have
-different log levels between local logging and syslog logging (i.e. respect the `priority` argument
-passed to `NewSyslogHook()`), you need to implement the `logrus_syslog.SyslogHook` interface
-overriding `Levels()` to return only the log levels you're interested on.
-
-The following example shows how to log at **DEBUG** level for local logging and **WARN** level for
-syslog logging:
-
-```go
-package main
-
-import (
-	"log/syslog"
-
-	log "github.com/sirupsen/logrus"
-	logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
-)
-
-type customHook struct {
-	*logrus_syslog.SyslogHook
-}
-
-func (h *customHook) Levels() []log.Level {
-	return []log.Level{log.WarnLevel}
-}
-
-func main() {
-	log.SetLevel(log.DebugLevel)
-
-	hook, err := logrus_syslog.NewSyslogHook("tcp", "localhost:5140", syslog.LOG_WARNING, "myTag")
-	if err != nil {
-		panic(err)
-	}
-
-	log.AddHook(&customHook{hook})
-
-	//...
-}
-```
