+## Ingress Class Setup
+Create a file anywhere with name as `ingressclass.yaml` and paste the following lines inside it:
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: IngressClass
+metadata:
+  name: nginx-ext
+spec:
+  controller: k8s.io/ingress-nginx
+```
+Save the file and run the following command:
+```
+kubectl apply -f ingressclass.yaml
+```
+Now, we need to restart the ingress nginx controller, to do that hit the command:
+```
+kubectl rollout restart deploy/ingress-nginx-controller
+```

 # USING THE DEPLOYED APPS
 
+## Determining the IP Address - Local
+If you are using a local environment, then you need to run the following commands in order to fetch the IP address of the ingress cluster:
+```
+kubectl get ingress -n <namespace>
+```
+You'll get an output something similar to this:
+```
+NAME                 CLASS       HOSTS                                     ADDRESS          PORTS   AGE
+greenbank-backend    nginx-ext   greenbank.local,greenbank-specapi.local   192.168.35.121   80      5h28m
+...
+```
+In your host file, you need to add an entry for the address you receive here (Here, for example it is `192.168.35.121`) and add the hosts in this entry as mentioned below.
+
+## Determining the IP Address - Remote
+In case you are using a remote virtual instance to deploy the mojafos, you'll need to create the entry of the public IP address of your instance in the host file of your machine instead of the IP of the ingress cluster.

 ## Accessing Mojaloop
 The Mojafos scripts add the required host names to the 127.0.0.1 entry in the /etc/hosts of the "install system" i.e. the system where mojafos is run. To access Mojaloop from beyond this system it is necessary to:-
