+            --version="v0.9.1" --create-namespace --namespace=kueue-system
 ```
 
-then:
+## Build
+Clone the kueue repository and build the projects:

+cd backend && make debug
 ```
 
-## Expose
-```
-oc create route edge --service=svc/backend

-```
+In another terminal run:
 
-## Configure
 ```
-BACKEND_URL=$(oc get route backend -o jsonpath='{.spec.host}')
-FRONTEND_URL=$(oc get route frontend -o jsonpath='{.spec.host}')
-oc set env deployment/backend  FRONTEND_URL=https://$FRONTEND_URL

+cd frontend && make debug
 ```

 ## Test
+Create test data using the resources in `examples/` directory.
 
 ```
-oc create -f https://raw.githubusercontent.com/opendatahub-io/distributed-workloads/2c6a14f792b8d94ad3fc2146316e52ace33b6a1e/examples/kueue-usage/kueue-with-jobs/00-common.yaml
+oc create -f examples/
 ```
-And check that you have some data in the Resource Flavors tab of the application.
+And check that you have some data on the dashboard.
