Does anybody know who to configure Logstash Slack output section in `logstash.conf`?

I tried to do the following using this docs [https://github.com/cyli/logstash-output-slack:](https://github.com/cyli/logstash-output-slack:)

```
slack {
  url => "..."
  channel => ["..."]
  attachments => [{"color" => "#36a64f"},{"title" => "This is a title %{title}"},{"author_name" => %{name}}]
}

```

I received the message but attachment was not formatted properly:  
the color was not set, `%{title}` and `%{name}` fields haven't been transformed to its values.

Could anybody clarify how to set the attachment format correctly?

Is there any clear documentation for Logstash-slack plugin?
