+Copy the configuration templates and change the file according to your needs.
 
 ```bash
 # in folder deployment/digital-ocean/https/
-$ kubectl apply -f issuer.yaml
+cp templates/issuer.template.yaml ./issuer.yaml
+cp templates/ingress.template.yaml ./ingress.yaml
 ```
 
-Create an ingress service in namespace `human-connection`. _Change the domain name_ according to your needs:
+At least, **change email addresses** in `issuer.yaml`. For sure you also want
+to _change the domain name_ in `ingress.yaml`.
+
+Once you are done, apply the configuration:
 
 ```bash
 # in folder deployment/digital-ocean/https/
-$ kubectl apply -f ingress.yaml
+$ kubectl apply -f .
 ```
 
+By now, your cluster should have an external IP address assigned. If you visit
+your dashboard, this is how it should look like:
