 # Slacker-Logs
 Provides interface to Slack chat from Laravel/Lumen logging.
 # Installation
-## Composer
+## Download
+### Via Composer
 To install via Composer first make sure Composer is installed.  
 Then need to simply run the command to require the package.  
 `composer require exposuresoftware/slackerlogs`
+## Register with the Container
+In order to make using this package you are only required to write a very simple class and register it
+with your application.
+### Create a Provider
+You `Provider` class can be named whatever you wish but **must** extend the `ExposureSoftware\SlackLogs\Providers\LoggerProvider`
+class.  
+This can be as simple as
+```
+<?php
+
+namespace App\Providers;
+
+use ExposureSoftware\SlackLogs\Providers\LoggerProvider;
+
+class SlackLogProvider extends LoggerProvider {
+    protected $channel = ...;
+    protected $user = ...;
+    protected $hook = ...;
+    protected $level = ...;
+}
+```
+Where each of the values are set to to the values for your application.  
+`$channel` should be the channel name you wish to direct logs to. It should include the `#` that precedes all Slack 
+channels.  
+`$user` is the user that the message will appear to come from. This does not have to be an actual user on your team.  
+`$hook` is the [webhook](https://api.slack.com/incoming-webhooks) your integration will use. Please see the Slack 
+documentation in the link regarding how to set this up and get your webhook.  
+`$level` is an the integer value of the log level you wish to report. This and any higher log levels will be sent to
+Slack. See `Monolog\Logger` for these values and constants available.  
+The available log levels are:
+> DEBUG     = 100
+> INFO      = 200
+> NOTICE    = 250
+> WARNING   = 300
+> ERROR     = 400
+> CRITICAL  = 500
+> ALERT     = 550
+> EMERGENCY = 600
+### Register the Provider with the application
+Add the line to your providers array as follows:
+```
+'providers' => [
+   ...,
+   'App\Providers\SlackLogProvider'
+},
+```
+Changing the fully namespaced class to the name of your `Provider`.
