 # matterbridge
 
-Simple bridge between mattermost and IRC. Uses the in/outgoing webhooks.  
-Relays public channel messages between mattermost and IRC.  
+Simple bridge between mattermost and IRC. 
 
-Requires mattermost 1.2.0+
+* Relays public channel messages between mattermost and IRC.
+* Supports multiple mattermost and irc channels.
+* Matterbridge -plus also works with private groups on your mattermost.
 
-There is also [matterbridge-plus] (https://github.com/42wim/matterbridge-plus) which uses the mattermost API and needs a dedicated user (bot). But requires no incoming/outgoing webhook setup. 
+This project has now [matterbridge-plus](https://github.com/42wim/matterbridge-plus/) merged in. 
+Breaking changes for matterbridge can be found in [migration](https://github.com/42wim/matterbridge/blob/master/migration.md)
+Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
+
+Configuration changes since v0.5.0 can be found in [changelog.md] (https://github.com/42wim/matterbridge/blob/master/changelog.md)
+
+## Requirements:
+* [Mattermost] (https://github.com/mattermost/platform/)
+### Compatibility
+* Matterbridge v0.6.0 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.
 
 ## binaries
-Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/tag/v0.4)
+Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)

-* 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

+# v0.6.0
+## Breaking changes from 0.5 to 0.6
+### commandline
+* -plus switch deprecated. Use ```Plus=true``` or ```Plus``` in ```[general]``` section
+### IRC section
+* ```Enabled``` added (default false)
+Add ```Enabled=true``` or ```Enabled``` to the ```[IRC]``` section if you want to enable the IRC bridge
+### Mattermost section
+* ```Enabled``` added (default false)
+Add ```Enabled=true``` or ```Enabled``` to the ```[mattermost]``` section if you want to enable the mattermostbridge
+### General section
+* Use ```Plus=true``` or ```Plus``` in ```[general]``` section to enable the API version of matterbridge
+
+## New features
+* Matterbridge now bridges between any specified protocol (not only mattermost anymore) 
+* XMPP support added.  See matterbridge.conf.sample for more information
+* RemoteNickFormat {BRIDGE} variable added
+You can now add the originating bridge to ```RemoteNickFormat```  
+eg ```RemoteNickFormat="[{BRIDGE}] <{NICK}> "```
