The quickstarts tell users to run
$ helm install microprofile-openapi -f charts/helm.yaml wildfly/wildfly
and then
oc get deployment microprofile-openapi -w
and then tells them to inspect the output. This is both verbose and a bit fiddly.

Instead Helm comes with a --wait flag, and a configurable timeout, so my suggestion is to replace those commands with the much simpler
helm install "${application}" todo-backend-chart/ --wait --timeout=10m0s

The timeout shown is the default, and it should hopefully be clear enough to users what they need to adjust if it is not long enough.
