+# Kapp Overview
+
+The Kapp CLI understands how to install and update applications on Kubernetes.
+In the Kapp way of thinking, an "application" is a collection of Kubernetes resources that can be considered
+parts of a single thing.
+
+Full details about the Kapp CLI are here: https://carvel.dev/kapp/
+
+## Creating a Kubernetes Application
+
+Suppose we want to install an application and make it available on our cluster. This might involve the
+following:
+
+1. Create a namespace
+1. Create a deployment
+1. Create a service
+
+These resources work together to comprise the application. But they are independent resources and could be
+managed independantly. If we need to make changes, or delete the application, we need to remember to work
+with every resource.
+
+Further need to make these resources in the correct order. The namespace would need to exist before the other
+resources could be added to it.
+
+```shell
+kapp deploy -a kuard -f .\kuard-application\
+
+kapp inspect -a kuard
+```
