+* Development releases (follows master) can be downloaded [here](https://dl.bintray.com/42wim/nightly/)
+
+### Building
+Go 1.8+ 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).
+
+After Go is setup, download matterbridge to your $GOPATH directory.
 
 ```
 cd $GOPATH
-go get https://github.com/42wim/matterbridge
+go get github.com/42wim/matterbridge
 ```
 
 You should now have matterbridge binary in the bin directory:

-## 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.  
+## Configuration
+### Basic configuration
+See [howto](https://github.com/42wim/matterbridge/wiki/How-to-create-your-config) for a step by step walkthrough for creating your configuration.
 
-Matterbridge will:
-* start a webserver listening on the port specified in the configuration.
-* connect to specified irc server and channel.
-* send messages from mattermost to irc and vice versa, messages in mattermost will appear with irc-nick
+### Advanced configuration
+* [matterbridge.toml.sample](https://github.com/42wim/matterbridge/blob/master/matterbridge.toml.sample) for documentation and an example.
 
-## config
-### matterbridge
-matterbridge looks for matterbridge.conf in current directory.

+[slack.test]
+Token="yourslacktoken"
+PrefixMessagesWithNick=true
 
-* 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)

+    name = "mygateway"
+    enable=true
 
+    [[gateway.inout]]
+    account = "discord.test"
+    channel="general"

+# v1.12.0
+
+## Breaking changes
+The slack bridge has been split in a `slack-legacy` and `slack` bridge.
+If you're still using `legacy tokens` and want to keep using them you'll have to rename `slack` to `slack-legacy` in your configuration. See [wiki](https://github.com/42wim/matterbridge/wiki/Section-Slack-(basic)#legacy-configuration) for more information.
+
+To migrate to the new bot-token based setup you can follow the instructions [here](https://github.com/42wim/matterbridge/wiki/Slack-bot-setup).
+
+Slack legacy tokens may be deprecated by Slack at short notice, so it is STRONGLY recommended to use a proper bot-token instead.
+

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+You can also define your own `io.Writer` in case you want to persist the logs somewhere.
+For example keeping the errors on file
+
+``` Go
+logFile, err := os.Create("gitter.log")
+api.SetDebug(true, logFile)
+```
+
+##### App Engine
+
+Initialize app engine client and continue as usual
+
+``` Go
+c := appengine.NewContext(r)
+client := urlfetch.Client(c)
+
+api := gitter.New("YOUR_ACCESS_TOKEN")
+api.SetClient(client)
+```

+# Steam for Go
+
+This library implements Steam's protocol to allow automation of different actions on Steam without running an actual Steam client. It is based on [SteamKit2](https://github.com/SteamRE/SteamKit), a .NET library.
+
+In addition, it contains APIs to Steam Community features, like trade offers and inventories.
+
+Some of the currently implemented features:
+
+  * Trading and trade offers, including inventories and notifications
+  * Friend and group management
+  * Chatting with friends
+  * Persona states (online, offline, looking to trade, etc.)
+  * SteamGuard with two-factor authentication
+  * Team Fortress 2: Crafting, moving, naming and deleting items
+
+If this is useful to you, there's also the [go-steamapi](https://github.com/Philipp15b/go-steamapi) package that wraps some of the official Steam Web API's types.
+
+## Installation
+
+    go get github.com/Philipp15b/go-steam
+
+## Usage
+
+You can view the documentation with the [`godoc`](http://golang.org/cmd/godoc) tool or
+[online on godoc.org](http://godoc.org/github.com/Philipp15b/go-steam).
+
+You should also take a look at the following sub-packages:
+
+  * [`gsbot`](http://godoc.org/github.com/Philipp15b/go-steam/gsbot) utilites that make writing bots easier
+  * [example bot](http://godoc.org/github.com/Philipp15b/go-steam/gsbot/gsbot) and [its source code](https://github.com/Philipp15b/go-steam/blob/master/gsbot/gsbot/gsbot.go)
+  * [`trade`](http://godoc.org/github.com/Philipp15b/go-steam/trade) for trading
+  * [`tradeoffer`](http://godoc.org/github.com/Philipp15b/go-steam/tradeoffer) for trade offers
+  * [`economy/inventory`](http://godoc.org/github.com/Philipp15b/go-steam/economy/inventory) for inventories
+  * [`tf2`](http://godoc.org/github.com/Philipp15b/go-steam/tf2) for Team Fortress 2 related things
+
+## Working with go-steam
+
+Whether you want to develop your own Steam bot or directly work on go-steam itself, there are are few things to know.
+
+ * If something is not working, check first if the same operation works (under the same conditions!) in the Steam client on that account. Maybe there's something go-steam doesn't handle correctly or you're missing a warning that's not obviously shown in go-steam. This is particularly important when working with trading since there are [restrictions](https://support.steampowered.com/kb_article.php?ref=1047-edfm-2932), for example newly authorized devices will not be able to trade for seven days.
+ * Since Steam does not maintain a public API for most of the things go-steam implements, you can expect that sometimes things break randomly. Especially the `trade` and `tradeoffer` packages have been affected in the past.
+ * Always gather as much information as possible. When you file an issue, be as precise and complete as you can. This makes debugging way easier.
+ * If you haven't noticed yet, expect to find lots of things out yourself. Debugging can be complicated and Steam's internals are too.
+ * Sometimes things break and other [SteamKit ports](https://github.com/SteamRE/SteamKit/wiki/Ports) are fixed already. Maybe take a look what people are saying over there? There's also the [SteamKit IRC channel](https://github.com/SteamRE/SteamKit/wiki#contact).
+
+## Updating go-steam to a new SteamKit version
+
+To update go-steam to a new version of SteamKit, do the following:
+
+	go get github.com/golang/protobuf/protoc-gen-go/
+    git submodule init && git submodule update
+    cd generator
+    go run generator.go clean proto steamlang
+
+Make sure that `$GOPATH/bin` / `protoc-gen-go` is in your `$PATH`. You'll also need [`protoc`](https://developers.google.com/protocol-buffers/docs/downloads), the protocol buffer compiler. At the moment, we use Protocol Buffers 2.6.1 with `proco-gen-go`-[2402d76](https://github.com/golang/protobuf/tree/2402d76f3d41f928c7902a765dfc872356dd3aad).
+
+To compile the Steam Language files, you also need the [.NET Framework](https://www.microsoft.com/net/downloads)
+on Windows or [mono](http://www.go-mono.com/mono-downloads/download.html) on other operating systems.
+
+Apply the protocol changes where necessary.

+
+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.

+/*
+This package includes some basics for the Steam protocol. It defines basic interfaces that are used throughout go-steam:
+There is IMsg, which is extended by IClientMsg (sent after logging in) and abstracts over
+the outgoing message types. Both interfaces are implemented by ClientMsgProtobuf and ClientMsg.
+Msg is like ClientMsg, but it is used for sending messages before logging in.
+
+There is also the concept of a Packet: This is a type for incoming messages where only
+the header is deserialized. It therefore only contains EMsg data, job information and the remaining data.
+Its contents can then be read via the Read* methods which read data into a MessageBody - a type which is Serializable and
+has an EMsg.
+
+In addition, there are extra types for communication with the Game Coordinator (GC) included in the gamecoordinator sub-package.
+For outgoing messages the IGCMsg interface is used which is implemented by GCMsgProtobuf and GCMsg.
+Incoming messages are of the GCPacket type and are read like regular Packets.
+
+The actual messages and enums are in the sub-packages steamlang and protobuf, generated from the SteamKit data.
