-* [Mattermost] (https://github.com/mattermost/platform/)
-* [IRC] (http://www.mirc.com/servers.html)
-* [XMPP] (https://jabber.org)
-* [Gitter] (https://gitter.im)
-* [Slack] (https://www.slack.com)
-
-## binaries
-Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)
-* For use with mattermost 3.3.0+ [v0.6.1](https://github.com/42wim/matterircd/releases/tag/v0.6.1)
-* For use with mattermost 3.0.0-3.2.0 [v0.5.0](https://github.com/42wim/matterircd/releases/tag/v0.5.0)
-
-
-## Docker
-Create your matterbridge.conf file locally eg in ```/tmp/matterbridge.conf```
-
-```
-docker run -ti -v /tmp/matterbridge.conf:/matterbridge.conf 42wim/matterbridge:0.6.1
-```
-
-## Compatibility
-### Mattermost 
-* Matterbridge v0.6.1 works with mattermost 3.3.0 and higher [3.3.0 release](https://github.com/mattermost/platform/releases/tag/v3.3.0)
-* Matterbridge v0.5.0 works with mattermost 3.0.0 - 3.2.0 [3.2.0 release](https://github.com/mattermost/platform/releases/tag/v3.2.0)
-
-
-#### Webhooks version
-* Configured incoming/outgoing [webhooks](https://www.mattermost.org/webhooks/) on your mattermost instance.
-
-#### Plus (API) version
-* A dedicated user(bot) on your mattermost instance.
-
-
-## building
-Go 1.6+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)
-
-```
-cd $GOPATH
-go get github.com/42wim/matterbridge
-```
-
-You should now have matterbridge binary in the bin directory:
-
-```
-$ ls bin/
-matterbridge
-```
-
-## running
-1) Copy the matterbridge.conf.sample to matterbridge.conf in the same directory as the matterbridge binary.  
-2) Edit matterbridge.conf with the settings for your environment. See below for more config information.  
-3) Now you can run matterbridge. 
-
-```
-Usage of ./matterbridge:
-  -conf string
-        config file (default "matterbridge.conf")
-  -debug
-        enable debug
-  -plus
-        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
-  -version
-        show version
-```
-
-## config
-### matterbridge
-matterbridge looks for matterbridge.conf in current directory. (use -conf to specify another file)
-
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
-
-### mattermost
-#### webhooks version
-You'll have to configure the incoming and outgoing webhooks. 
-
-* incoming webhooks
-Go to "account settings" - integrations - "incoming webhooks".  
-Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
-This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
-
-* outgoing webhooks
-Go to "account settings" - integrations - "outgoing webhooks".  
-Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.  
-
-e.g. http://192.168.1.1:9999 (192.168.1.1:9999 is the BindAddress specified in [mattermost] section of matterbridge.conf)
-
-#### plus version
-You'll have to create a new dedicated user on your mattermost instance.
-Specify the login and password in [mattermost] section of matterbridge.conf
-
-## FAQ
-Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
-### Mattermost doesn't show the IRC nicks
-If you're running the webhooks version, this can be fixed by either:
-* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-If you're running the plus version you'll need to:
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-Also look at the ```RemoteNickFormat``` setting.

-## FAQ
-Please look at [matterbridge.toml.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample) for more information first. 
-### Mattermost doesn't show the IRC nicks
-If you're running the webhooks version, this can be fixed by either:
-* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.toml.
-
-If you're running the plus version you'll need to:
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.toml.
-
-Also look at the ```RemoteNickFormat``` setting.

+This package allows you to automate actions on Valve's Steam network. It is a Go port of SteamKit.
+
+To login, you'll have to create a new Client first. Then connect to the Steam network
+and wait for a ConnectedCallback. Then you may call the Login method in the Auth module
+with your login information. This is covered in more detail in the method's documentation. After you've
+received the LoggedOnEvent, you should set your persona state to online to receive friend lists etc.
+
+Example code
+
+You can also find a running example in the `gsbot` package.
+
+	package main
+
+	import (
+		"io/ioutil"
+		"log"
+
+		"github.com/Philipp15b/go-steam"
+		"github.com/Philipp15b/go-steam/protocol/steamlang"
+	)
+
+	func main() {
+		myLoginInfo := new(steam.LogOnDetails)
+		myLoginInfo.Username = "Your username"
+		myLoginInfo.Password = "Your password"
+
+		client := steam.NewClient()
+		client.Connect()
+		for event := range client.Events() {
+			switch e := event.(type) {
+			case *steam.ConnectedEvent:
+				client.Auth.LogOn(myLoginInfo)
+			case *steam.MachineAuthUpdateEvent:
+				ioutil.WriteFile("sentry", e.Hash, 0666)
+			case *steam.LoggedOnEvent:
+				client.Social.SetPersonaState(steamlang.EPersonaState_Online)
+			case steam.FatalErrorEvent:
+				log.Print(e)
+			case error:
+				log.Print(e)
+			}
+		}
+	}
+
+
+Events
+
+go-steam emits events that can be read via Client.Events(). Although the channel has the type interface{},
+only types from this package ending with "Event" and errors will be emitted.
