+**Index templates**
+
+This plugin creates ElasticSearch indices by merely writing to them. Consider using [Index Templates](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/indices-templates.html) to gain control of what get indexed and how. See [this example](https://github.com/uken/fluent-plugin-elasticsearch/issues/33#issuecomment-38693282) for a good starting point.
