+### Ghost Application
+
+"Ghost is a powerful app for new-media creators to publish, share, and grow a business around their content. It comes with modern tools to build a website, publish content, send newsletters & offer paid subscriptions to members."
+https://ghost.org/
+
+### Quick start
+
+#### Get KPT Pacakge
 ```bash
-# Fetch ghost helm charts
-helm fetch --untar bitnami/ghost
-# By default networking, metrics are disabled. 
-helm template example ghost > rendered.yaml
-rm -rf ghost
-# Restructure the KRM resources by app. This should give two directories: ./mariadb /ghost 
-kubectl-slice -f rendered.yaml --template '{{ index "app.kubernetes.io/name" .metadata.labels }}/{{.kind | lower}}-{{.metadata.name|dottodash}}.yaml' -o ghost
-rm rendered.yaml
+export NAMESPACE=<YOUR NAMESPACE>
+# make sure the namespace is correct and exists. Otherwise, create the namespace
+kubectl create namespace ${NAMESPACE}
+
+# You get this Ghost package by running
+kpt pkg get https://github.com/GoogleContainerTools/kpt.git/package-examples/ghost@main ${NAMESPACE} --for-deployment
+```
+
+#### Update the KRM resources to your own data
+
+Updating the KRM resources are easy with variant constructor
+```bash
+kpt fn render ${NAMESPACE}
+```
+
+#### Deploy the KRM resources to your cluster
+
+```bash
+# Initialize inventory info. You only need to run this if do not have resourcesgroup.yaml
+kpt live init ${NAMESPACE}
+
+kpt live apply ${NAMESPACE}
 ```
