+    | kubectl apply -f -
+
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/default-backend.yaml \
+    | kubectl apply -f -

+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/without-rbac.yaml \
+    | kubectl apply -f -
+```
+
+### Install with RBAC roles
+
+Please check the [RBAC](rbac.md) document.
+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/rbac.yaml \
+    | kubectl apply -f -
+
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/with-rbac.yaml \
+    | kubectl apply -f -
+```
+
+Custom Service Provider Deployment
+----------------------------------
+
+There are cloud provider specific yaml files.
+
+### minikube
+
+For standard usage:
+
+``` console
+minikube addons enable ingress
+```
+
+For development:
+
+1.  Disable the ingress addon:
+
+    ``` console
+    $ minikube addons disable ingress
+    ```
+
+2.  Use the [docker daemon](https://github.com/kubernetes/minikube/blob/master/docs/reusing_the_docker_daemon.md)
+3.  [Build the image](../docs/development.md)
+4.  Perform [Mandatory commands](#mandatory-commands)
+5.  Install the `nginx-ingress-controller` deployment [without RBAC roles](#install-without-rbac-roles) or [with RBAC roles](#install-with-rbac-roles)
+6.  Edit the `nginx-ingress-controller` deployment to use your custom image. Local images can be seen by performing `docker images`.
+
+    ``` console
+    $ kubectl edit deployment nginx-ingress-controller -n ingress-nginx
+    ```
+
+    edit the following section:
+
+    ``` yaml
+    image: <IMAGE-NAME>:<TAG>
+    imagePullPolicy: IfNotPresent
+    name: nginx-ingress-controller
+    ```
+
+7.  Confirm the `nginx-ingress-controller` deployment exists:
+
+``` console
+$ kubectl get pods -n ingress-nginx 
+NAME                                       READY     STATUS    RESTARTS   AGE
+default-http-backend-66b447d9cf-rrlf9      1/1       Running   0          12s
+nginx-ingress-controller-fdcdcd6dd-vvpgs   1/1       Running   0          11s
+```
+
+### AWS
+
+In AWS we use an Elastic Load Balancer (ELB) to expose the NGINX Ingress controller behind a Service of `Type=LoadBalancer`.
+This setup requires to choose in which layer (L4 or L7) we want to configure the ELB:
+
+-   [Layer 4](https://en.wikipedia.org/wiki/OSI_model#Layer_4:_Transport_Layer): use TCP as the listener protocol for ports 80 and 443.
+-   [Layer 7](https://en.wikipedia.org/wiki/OSI_model#Layer_7:_Application_Layer): use HTTP as the listener protocol for port 80 and terminate TLS in the ELB
+
+Patch the nginx ingress controller deployment to add the flag `--publish-service`
+
+``` console
+kubectl patch deployment -n ingress-nginx nginx-ingress-controller --type='json' \
+  --patch="$(curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/publish-service-patch.yaml)"
+```
+
+For L4:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/service-l4.yaml
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l4.yaml
+```
+
+For L7:
+
+Change line of the file `provider/aws/service-l7.yaml` replacing the dummy id with a valid one `"arn:aws:acm:us-west-2:XXXXXXXX:certificate/XXXXXX-XXXXXXX-XXXXXXX-XXXXXXXX"`
+Then execute:
+
+``` console
+kubectl apply -f provider/aws/service-l7.yaml
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/aws/patch-configmap-l7.yaml
+```
+
+This example creates an ELB with just two listeners, one in port 80 and another in port 443
+
+![Listeners](../docs/images/elb-l7-listener.png)
+
+If the ingress controller uses RBAC run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-with-rbac.yaml
+```
+
+If not run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-without-rbac.yaml
+```
+
+### GCE - GKE
+
+Patch the nginx ingress controller deployment to add the flag `--publish-service`
+
+``` console
+kubectl patch deployment -n ingress-nginx nginx-ingress-controller --type='json' \
+  --patch="$(curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/publish-service-patch.yaml)"
+```
+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/gce-gke/service.yaml \
+    | kubectl apply -f -
+```
+
+If the ingress controller uses RBAC run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-with-rbac.yaml
+```
+
+If not run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-without-rbac.yaml
+```
+
+**Important Note:** proxy protocol is not supported in GCE/GKE
+
+### Azure
+
+Patch the nginx ingress controller deployment to add the flag `--publish-service`
+
+``` console
+kubectl patch deployment -n ingress-nginx nginx-ingress-controller --type='json' \
+  --patch="$(curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/publish-service-patch.yaml)"
+```
+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/azure/service.yaml \
+    | kubectl apply -f -
+```
+
+If the ingress controller uses RBAC run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-with-rbac.yaml
+```
+
+If not run:
+
+``` console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/patch-service-without-rbac.yaml
+```
+
+**Important Note:** proxy protocol is not supported in GCE/GKE
+
+### Baremetal
+
+Using [NodePort](https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport):
+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/baremetal/service-nodeport.yaml \
+    | kubectl apply -f -
+```
+
+Using Helm
+----------
+
+NGINX Ingress controller can be installed via [Helm](https://helm.sh/) using the chart [stable/nginx](https://github.com/kubernetes/charts/tree/master/stable/nginx-ingress) from the official charts repository.
+To install the chart with the release name `my-nginx`:
+
+``` console
+helm install stable/nginx-ingress --name my-nginx
+```
+
+If the kubernetes cluster has RBAC enabled, then run:
+
+``` console
+helm install stable/nginx-ingress --name my-nginx --set rbac.create=true
+```
+
+Verify installation
+-------------------
+
+To check if the ingress controller pods have started, run the following command:
+
+``` console
+kubectl get pods --all-namespaces -l app=ingress-nginx --watch
+```
+
+Once the operator pods are running, you can cancel the above command by typing `Ctrl+C`.
+Now, you are ready to create your first ingress.
+
+Detect installed version
+------------------------
+
+To detect which version of the ingress controller is running, exec into the pod and run `nginx-ingress-controller version` command.
+
+``` console
+POD_NAMESPACE=ingress-nginx
+POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app=ingress-nginx -o jsonpath={.items[0].metadata.name})
+kubectl exec -it $POD_NAME -n $POD_NAMESPACE -- /nginx-ingress-controller --version
+```
+
+Deploying the config-map
+------------------------
+
+A config map can be used to configure system components for the nginx-controller. In order to begin using a config-map
+make sure it has been created and is being used in the deployment.
+
+It is created as seen in the [Mandatory Commands](#mandatory-commands) section above.
+
+``` console
+curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/configmap.yaml \
+    | kubectl apply -f -
+```
+
+and is setup to be used in the deployment [without-rbac](without-rbac.yaml) or [with-rbac](with-rbac.yaml) with the following line:
+
+``` yaml
+- --configmap=$(POD_NAMESPACE)/nginx-configuration
+```
+
+For information on using the config-map, see its [user-guide](../docs/user-guide/configmap.md).
