+### 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
+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}
+```
