-# Papertrail Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
-
-[Papertrail](https://papertrailapp.com) provides hosted log management. Once stored in Papertrail, you can [group](http://help.papertrailapp.com/kb/how-it-works/groups/) your logs on various dimensions, [search](http://help.papertrailapp.com/kb/how-it-works/search-syntax) them, and trigger [alerts](http://help.papertrailapp.com/kb/how-it-works/alerts).
-
-In most deployments, you'll want to send logs to Papertrail via their [remote_syslog](http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-text-log-files-in-unix/) daemon, which requires no application-specific configuration. This hook is intended for relatively low-volume logging, likely in managed cloud hosting deployments where installing `remote_syslog` is not possible.
-
-## Usage
-
-You can find your Papertrail UDP port on your [Papertrail account page](https://papertrailapp.com/account/destinations). Substitute it below for `YOUR_PAPERTRAIL_UDP_PORT`.
-
-For `YOUR_APP_NAME`, substitute a short string that will readily identify your application or service in the logs.
-
-```go
-import (
-  "log/syslog"
-  "github.com/Sirupsen/logrus"
-  "github.com/Sirupsen/logrus/hooks/papertrail"
-)
-
-func main() {
-  log       := logrus.New()
-  hook, err := logrus_papertrail.NewPapertrailHook("logs.papertrailapp.com", YOUR_PAPERTRAIL_UDP_PORT, YOUR_APP_NAME)
-
-  if err == nil {
-    log.Hooks.Add(hook)
-  }
-}
