+Once all pods are running, access the Mifos web application:

+
+This opens the Mifos X web application in your browser. The nginx reverse proxy in the mifos-community pod forwards API requests to the fineract-server backend.

+- Username: `mifos`

+You can also access the Fineract API directly:

 To check the status of your containers on your local minikube Kubernetes cluster, run:

 You can check Fineract logs using:
