[End User] How to use this plugin?

Installing the plugin
Upload the package to your server using the Joomla! installer. Install this package just like you install all other packages.

Configuring the plugin
The plugin is automaticly enabled, but not yet active. You must go to the plugins, search for MS Slack and open its settings. Enable the plugin and fill in your webhook URL. You can find this URL in your Slack integration named "Incoming WebHooks". You can also find the additional events and custom events in the plugin configuration.

Adding custom events
Custom events can be added in the plugin configuration. Please read the documentation popups of the labels next to the inputs carefully! Enter the custom event name, that will be fired from another extension, and enable it. Enter a message in the editor below and test the event (like ordering in your website). When everything has been setup correctly, you should receive a Slack notification whenever the given event happens.
