+# matterbridge
+
+Simple bridge between mattermost and IRC. Uses the in/outgoing webhooks.
+Relays public channel messages between mattermost and IRC.
+
+Work in progress. 
+
+## building
+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 $GOPATH
+go get https://github.com/42wim/matterbridge
+```
+
+You should now have matterbridge binary in the bin directory:
+
+```
+$ 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.
+
+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
+
+## config
+### matterbridge
+matterbridge looks for matterbridge.conf in current directory.
+
+Look at matterbridge.conf.sample for an example
+
+
+```
+[IRC]
+server="irc.freenode.net"
+port=6667
+UseTLS=false
+SkipTLSVerify=true
+nick="matterbot"
+channel="#matterbridge"
+
+[mattermost]
+#url is your incoming webhook url (account settings - integrations - incoming webhooks)
+url="http://mattermost.yourdomain.com/hooks/incomingwebhookkey"  
+#port the bridge webserver will listen on
+port=9999
+```
+
+### mattermost
+You'll have to configure the incoming en 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 (9999 is the port specified in [mattermost] section of matterbridge.conf)
