+# Mattermost chat plugin for Redmine
+
+This plugin posts updates to issues in your Redmine installation to a Mattermost
+channel.
+
+## Screenshot

+
+## Installation
+
+From your Redmine plugins directory, clone this repository as `redmine_mattermost` (note
+the underscore!):
+
+    git clone https://github.com/altsol/redmine_mattermost.git redmine_mattermost
+
+You will also need the `httpclient` dependency, which can be installed by running
+
+    bundle install
+
+from the plugin directory.
+
+Restart Redmine, and you should see the plugin show up in the Plugins page.
+Under the configuration options, set the Mattermost API URL to the URL for an
+Incoming WebHook integration in your Mattermost account.
+
+## Customized Routing
+
+You can also route messages to different channels on a per-project basis. To
+do this, create a project custom field (Administration > Custom fields > Project)
+named `Mattermost Channel`. If no custom channel is defined for a project, the parent
+project will be checked (or the default will be used). To prevent all notifications
+from being sent for a project, set the custom channel to `-`.
+
+For more information, see http://www.redmine.org/projects/redmine/wiki/Plugins.
+
+## Credits
+
+The source code is forked from https://github.com/sciyoshi/redmine-slack. Special thanks to the original author and contributors for making this awesome hook for Redmine. This fork is just refactored to use Mattermost-namespaced configuration options in order to use both hooks (Mattermost and Slack) in a Redmine installation.
