 ## Configuration
 
-The plugin is enabled by default. Enabling basic authorization will disable the default HTTP Transport module.
+Once the plugin is installed it can be configured in the [elasticsearch modules configuration file](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html#settings). See the [elasticserach directory layout information](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup-dir-layout.html) for more information about the default paths of an ES installation.
