-=== "Iter8 for Knative"
-    Follow these steps to install Iter8 for Knative. 
+# Installation
 
+## Iter8
 
-    !!! example "Prerequisites"
-        1. Kubernetes cluster with [Knative Serving](https://knative.dev/docs/install/any-kubernetes-cluster/#installing-the-serving-component)
-        2. [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
-        3. [Kustomize v3](https://kubectl.docs.kubernetes.io/installation/kustomize/), and 
-        4. [Go 1.13+](https://golang.org/doc/install)
+!!! example "Prerequisites"
 
-    ## Step 1: Export TAG
-    ```shell
-    export TAG=v0.3.0-pre.4
-    ```
+    1. A Kubernetes cluster
+    2. [kubectl CLI](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
+
+Install Iter8 in your Kubernetes cluster as follows.
 
-    ## Step 2: Install iter8-monitoring
+```shell
+export TAG=v0.3.0-pre.5
+curl -s https://raw.githubusercontent.com/iter8-tools/iter8-install/main/install.sh | bash
+```
+
+??? info "Look inside install.sh"
     ```shell
-    kustomize build github.com/iter8-tools/iter8/install/monitoring/prometheus-operator/?ref=${TAG} | kubectl apply -f -
+    #!/bin/bash
+
+    set -e
+
+    # Step 0: Export TAG
+    export TAG="${TAG:-v0.3.0-pre.5}"

+    kubectl wait --for condition=ready --timeout=300s pods --all -n iter8-system
+
+    set +e
+    ```        
+
+## (Optional) Prometheus add-on
+
+Install Iter8's Prometheus add-on in your cluster as follows.
 
-    ## Step 3: Install Iter8
+```shell
+export TAG=v0.3.0-pre.5
+curl -s https://raw.githubusercontent.com/iter8-tools/iter8-install/main/install-prom-add-on.sh | bash
+```
+

+    kubectl apply -f https://raw.githubusercontent.com/iter8-tools/iter8-install/${TAG}/prometheus-add-on/service-monitors/build.yaml
 
-    ## Step 4: Install iter8ctl
-    ```shell
-    GO111MODULE=on GOBIN=/usr/local/bin go get github.com/iter8-tools/[email protected]
-    ```
+    echo "Verifying Prometheus-addon installation"
+    kubectl wait --for condition=ready --timeout=300s pods --all -n iter8-system
 
-    ## Optional: Customizing Iter8 install
+    set +e
+    ```
 
-    ### Prometheus URL
-    The URL of the Prometheus metrics backend is supplied as part of [this configmap](https://github.com/iter8-tools/iter8/blob/v0.2.5/install/iter8-analytics/config.yaml) during the install process. This URL is intended to match the location of the [iter8-monitoring install](#step-2-install-iter8-monitoring) above. To use your own Prometheus backend, replace the value of the metrics backend URL in the configmap during the install process with the URL of your Prometheus backend. You can use Kustomize or `sed` or any tool of your choice for this customization.
+??? note "Running Iter8 tutorials without this add-on"
+    When you installed Iter8 in the first step above, you also installed several *out-of-the-box* Iter8 metric resources. They are required for running the tutorials documented on this site. 
+
+    The out-of-the-box metric resources have a urlTemplate field. This field is configured as the URL of the Prometheus instance created in this step. 
 
-=== "Iter8 for KFServing"
-    An initial version of Iter8 for KFServing is available [here](https://github.com/iter8-tools/iter8-kfserving) along with installation instructions. An updated version is coming soon and will be documented here.
+    You can skip this step and still run Iter8 tutorials using your own Prometheus instance. To do so, ensure that your Prometheus instance scrapes the end-points that would have been scraped by the Prometheus instance created in this step, and configure the urlTemplate fields of Iter8 metric resources to the URL of your Prometheus instance.
+
+## (Optional) iter8ctl
+The iter8ctl CLI enables real-time observability of Iter8 experiments. 
+
+!!! example "Prerequisites"
+
+    Go 1.13+
 
-=== "Iter8 for Istio"
-    An earlier version of Iter8 for Istio is available [here](https://github.com/iter8-tools/iter8) along with installation instructions. An updated version is coming soon and will be documented here.
