+This plugin adds completion for the [Kind](https://kind.sigs.k8s.io/) tool, as well
+as a few aliases for easier use.
+
+To use it, add `kind` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... kind)
+```
+
+## Aliases
+

+| `kicc`  | `kind create cluster`        |
+| `kiccn` | `kind create cluster --name` |
+| `kigc`  | `kind get clusters`          |
+| `kidc`  | `kind delete cluster`        |
