+# Kubectl context manager
+Kubectl, the kubernetes client, needs context to work correctly. By default, it uses the file on `~/.kube/config`, which has an horrible design. With this plugin, the better approach is to not have a `~/.kube/config` file and `n` `~/.kube/something-config`. If you do so, you'll be able to manage multiple contexts easily.
+
+This plugin is based on the [aws](https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins#aws) one. The functions that provides are `ksp` and `kgp`. The first one let's you choose between the contexts and the second one shows which one is being used.
+
+See the `~/.kube` directory:
+
+```bash
+tree ~/.kube
+
+/home/whatever/.kube
+├── firstContext-config
+└── secondContext-config
+```
