 This script makes it easy to create the endpoint metadata, alert, and event documents needed to test Resolver in Kibana.
-The default behavior is to create 1 endpoint with 1 alert and a moderate number of events (random, typically on the order of 20).
+The default behavior is to create 1 endpoint with 1 alert and a moderate number of events (random, typically on the order of 20). **THE EVENT AND METADATA INDICES WILL BE DELETED AND REMADE BEFORE INSERTING.**
 A seed value can be provided as a string for the random number generator for repeatable behavior, useful for demos etc.
 
 The sample data generator script depends on ts-node, install with npm:
-`npm install -g ts-node`
+
+```npm install -g ts-node```

 Example command sequence to get ES and kibana running with sample data after installing ts-node:
-`yarn es snapshot` -> starts ES
-`npx yarn start --xpack.endpoint.enabled=true --no-base-path` -> starts kibana
-`cd ~/path/to/kibana/x-pack/plugins/endpoint`
-`yarn test:generate --auth elastic:changeme`

+```cd ~/path/to/kibana/x-pack/plugins/endpoint```
