+# Kubectl plugin
+
+This plugin adds completion for the [Kubernetes cluster manager](https://kubernetes.io/docs/reference/kubectl/kubectl/),
+as well as some aliases for common kubectl commands.
+
+To use it, add `kubectl` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... kubectl)
+```
+
