 ### Quick Start
 
-In order to execute the script you must have a running OpenSearch cluster so you can supply an endpoint for the data to be ingested too. The current iteration of this data script creates data in a cosine pattern with anomalies injected with a random seed throughout. The dataset created will have two categorical fields to test a multi-entity AD (of type `keyword`) and two fields that can act as the two features fields (cpuTime and jvmGcTime). These two fields are of type `double`.
