+
+## Details
+
+[Kubepug](https://kubepug.xyz/) is an open-source project and program that helps administrators of a Kubernetes cluster upgrade by finding deprecated APIs for resources that require either migration or removal from the cluster.
+
+These different API types are usually deprecated in one version and then removed or deleted in a future version based on a selected lifecycle. Kubepug detects these deprecations or deletions by allowing you to set your Kubernetes version, which it will use to validate your cluster or manifest files.
+
+### Objectives

+
+- How to install the Kubepug plugin using Krew
+- How to run KubePub to determine deprecated clusters and manifests
