+# K3K
+
+A Kubernetes in Kubernetes tool, k3k provides a way to run multiple embedded isolated k3s clusters on your kubernetes cluster.
+
+## Why?
+
+![alt text](https://github.com/galal-hussein/k3k/blob/main/hack/becausewecan.jpg?raw=true)
+
+
+## Usage
+
+K3K consists of a controller and a cli tool, the controller can be deployed via a helm chart and the cli can be downloaded from the releases page.
+
+### Deploy Controller
+
+[Helm](https://helm.sh) must be installed to use the charts.  Please refer to
+Helm's [documentation](https://helm.sh/docs) to get started.
+
+Once Helm has been set up correctly, add the repo as follows:
+
+  helm repo add k3k https://galal-hussein.github.io/k3k
+
+If you had already added this repo earlier, run `helm repo update` to retrieve
+the latest versions of the packages.  You can then run `helm search repo
+k3k` to see the charts.
+
+To install the k3k chart:
+
+    helm install my-k3k k3k/k3k
+
+To uninstall the chart:
+
+    helm delete my-k3k
+
+### Create a new cluster
+
+To create a new cluster you need to install and run the cli or create a cluster object, to install the cli:
+
+```
+wget https://github.com/galal-hussein/k3k/releases/download/v0.0.0-alpha2/k3k
+chmod +x k3k
+sudo cp k3k /usr/local/bin
+```
+
+To create a new cluster you can use:
+```
+k3k cluster create --name example-cluster --token test
+```
