+* Relays public channel messages between multiple mattermost, IRC, XMPP, Gitter, Slack, Discord, Telegram, Rocket.Chat, Hipchat (via xmpp), Matrix and Steam. 
-* [Support multiple gateways(bridges) for your protocols](https://github.com/42wim/matterbridge/wiki/Features#support-multiple-gatewaysbridges-for-your-protocols)
+  Pick and mix.
-* [Message edits and deletes](https://github.com/42wim/matterbridge/wiki/Features#message-edits-and-deletes)
+* Support private groups on your mattermost/slack.
-* Preserves threading when possible
+* Allow for bridging the same bridges, which means you can eg bridge between multiple mattermosts.
-* [Attachment / files handling](https://github.com/42wim/matterbridge/wiki/Features#attachment--files-handling)
+* The bridge is now a gateway which has support multiple in and out bridges. (and supports multiple gateways).
-* [Username and avatar spoofing](https://github.com/42wim/matterbridge/wiki/Features#username-and-avatar-spoofing)
+* Edits and delete messages across bridges that support it (mattermost,slack,discord,gitter,telegram)
-* [Private groups](https://github.com/42wim/matterbridge/wiki/Features#private-groups)

-## 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.
-
-## New features
-* general: New {GATEWAY} variable for `RemoteNickFormat` #501. See `RemoteNickFormat` in matterbridge.toml.sample.
-* general: New {CHANNEL} variable for `RemoteNickFormat` #515. See `RemoteNickFormat` in matterbridge.toml.sample.
-* general: Remove hyphens when auto-loading envvars from viper config #545
-* discord: You can mention discord-users from other bridges.
-* slack: Preserve threading between Slack instances #529. See `PreserveThreading` in matterbridge.toml.sample.
-* slack: Add ability to show when user is typing across Slack bridges #559
-* slack: Add rate-limiting
-* mattermost: Add support for mattermost [matterbridge plugin](https://github.com/matterbridge/mattermost-plugin)
-* api: Respond with message on connect. #550
-* api: Add a health endpoint to API #554
-
-## Bugfix
-* slack: Refactoring and making it better.
-* slack: Restore file comments coming from Slack. #583
-* irc: Fix IRC line splitting. #587

-- [Rooms](#rooms)
-- [Messages](#messages)

-
-##### Initialize
-``` Go
-api := gitter.New("YOUR_ACCESS_TOKEN")
-```
-
-##### Users
-
-- Get current user
-
-	``` Go
-	user, err := api.GetUser()
-	```
-
-##### Rooms
-
-- Get all rooms
-	``` Go
-	rooms, err := api.GetRooms()
-	```
-
-- Get room by id
-	``` Go
-	room, err := api.GetRoom("roomID")
-	```
-
-- Get rooms of some user
-	``` Go
-	rooms, err := api.GetRooms("userID")
-	```
-
-- Join room
-	``` Go
-	room, err := api.JoinRoom("roomID", "userID")
-	```
-	
-- Leave room
-	``` Go
-	room, err := api.LeaveRoom("roomID", "userID")
-	```
-
-- Get room id
-	``` Go
-	id, err := api.GetRoomId("room/uri")
-	```
-
-- Search gitter rooms
-	``` Go
-	rooms, err := api.SearchRooms("search/string")
-	```
-##### Messages
-
-- Get messages of room
-	``` Go
-	messages, err := api.GetMessages("roomID", nil)
-	```
-
-- Get one message
-	``` Go
-	message, err := api.GetMessage("roomID", "messageID")
-	```
-
-- Send message
-	``` Go
-	err := api.SendMessage("roomID", "free chat text")
-	```
-
-##### Stream
-
-Create stream to the room and start listening to incoming messages
-
-``` Go
-stream := api.Stream(room.Id)
-go api.Listen(stream)
-
-for {
-    event := <-stream.Event
-    switch ev := event.Data.(type) {
-    case *gitter.MessageReceived:
-        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
-    case *gitter.GitterConnectionClosed:
-        // connection was closed
-    }
-}
-```
-
-Close stream connection
-
-``` Go
-stream.Close()
-```
-
-##### Faye (Experimental)
-
-``` Go
-faye := api.Faye(room.ID)
-go faye.Listen()
-
-for {
-    event := <-faye.Event
-    switch ev := event.Data.(type) {
-    case *gitter.MessageReceived:
-        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
-    case *gitter.GitterConnectionClosed: //this one is never called in Faye
-        // connection was closed
-    }
-}
-```
-
-##### Debug
-
-You can print the internal errors by enabling debug to true
-
-``` Go
-api.SetDebug(true, nil)
-```
-
-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)
-```

+Package toml provides facilities for decoding and encoding TOML configuration
+files via reflection. There is also support for delaying decoding with
+the Primitive type, and querying the set of keys in a TOML document with the
+MetaData type.
+
+The specification implemented: https://github.com/toml-lang/toml
+
+The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
+whether a file is a valid TOML document. It can also be used to print the
+type of each key in a TOML document.
+
+Testing
+
+There are two important types of tests used for this package. The first is
+contained inside '*_test.go' files and uses the standard Go unit testing
+framework. These tests are primarily devoted to holistically testing the
+decoder and encoder.
+
+The second type of testing is used to verify the implementation's adherence
+to the TOML specification. These tests have been factored into their own
+project: https://github.com/BurntSushi/toml-test
+
+The reason the tests are in a separate project is so that they can be used by
+any implementation of TOML. Namely, it is language agnostic.
