 We recommend that you start Minikube with the following parameters, note that the `registry` addon must be enabled.
+Additionally, the ingress addon is also enabled facilitate data-index querying by using an Ingress. Note that the Ingress provided is just en example to expose the data-index graphiql.
+This is not mandatory, and in production environments you must provide your own setup if needed, or even use an OpenShift route, etc.

 To access the Data Index, using Minikube you can run:
 
 ```shell
-minikube service data-index-service-postgresql --url -n data-index-usecase 
+minikube ip
 ```
 
 Example output:
 ```
-http://192.168.49.2:30352
+192.168.49.2
 ```
-The output is the Data Index URL, so you can access the GraphiQL UI by using a url like this http://192.168.49.2:30352/grpahiql/  (host and por might be different in your installation.)

+Use the returned ip to access the data-index-service GraphiQL by using the Ingress with a url like this http://192.168.49.2/graphiql/ (that ip might be different in your installation.)
