+# Knative Inspect
+
+A light-weight debugging tool for Knative's system components which is heavily
+influenced by [github.com/k14s/kapp](https://github.com/k14s/kapp). It assumes
+Kubernetes as the backend for Knative.
+
+```
+Usage:
+  kni [flags]
+  kni [command]
+
+Available Commands:
+  config-changes Changes to Knative ConfigMaps
+  help           Help about any command
+  inspect        Inspect Knative services
+  kube-version   Print Kubernetes version
+  logs           Knative Component Logs
+  version        Print version
+
+Flags:
+  -h, --help   help for kni
+```
