 ```
 Usage of ./matterbridge:
   -conf string
-        config file (default "matterbridge.conf")
+        config file (default "matterbridge.toml")
   -debug
         enable debug
-  -plus
-        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
+  -gops
+        enable gops agent
   -version
         show version
 ```
 
-## config
-### matterbridge
-matterbridge looks for matterbridge.conf in current directory. (use -conf to specify another file)
+## Docker
+Create your matterbridge.toml file locally eg in ```/tmp/matterbridge.toml```
+```
+docker run -ti -v /tmp/matterbridge.toml:/matterbridge.toml 42wim/matterbridge
+```
 
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
+# Changelog

-### mattermost
-#### webhooks version
-You'll have to configure the incoming and outgoing webhooks. 
+# FAQ
 
-* 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)  
+See [FAQ](https://github.com/42wim/matterbridge/wiki/FAQ)
 
-* 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.

+## Bugfix since rc1
+* steam: Fix channel id bug in steam (channels are off by 0x18000000000000)
+* telegram: Add UseInsecureURL option for telegram (default false)
+  WARNING! If enabled this will relay GIF/stickers/documents and other attachments as URLs
+  Those URLs will contain your bot-token. This may not be what you want.
+  For now there is no secure way to relay GIF/stickers/documents without seeing your token.
+* irc: detect charset and try to convert it to utf-8 before sending it to other bridges. #209 #210
+* general: various improvements
+
+
+# v0.16.0-rc1
+## Breaking Changes
+* URL,UseAPI,BindAddress is deprecated. Your config has to be updated.
+  * URL => WebhookURL
+  * BindAddress => WebhookBindAddress
+  * UseAPI => removed 
+  This change allows you to specify a WebhookURL and a token (slack,discord), so that
+  messages will be sent with the webhook, but received via the token (API)
+  If you have not specified WebhookURL and WebhookBindAddress the API (login or token) 
+  will be used automatically. (no need for UseAPI)
+
+## New features
+* steam: New protocol support added (http://store.steampowered.com/)
+* discord: WebhookURL posting support added (thanks @saury07) #204
+  Discord API does not allow to change the name of the user posting, but webhooks does.

+* slack: Remove label from URLs (slack). #205
+
+# v0.15.0

+## New features
+* irc: Limit message length. ```MessageLength=400```
+  Maximum length of message sent to irc server. If it exceeds <message clipped> will be add to the message.
+* irc: Add NOPINGNICK option. 
+  The string "{NOPINGNICK}" (case sensitive) will be replaced by the actual nick / username, but with a ZWSP inside the nick, so the irc user with the same nick won't get pinged.   
+  See https://github.com/42wim/matterbridge/issues/175 for more information

+Package toml provides facilities for decoding and encoding TOML configuration

+
+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.
