 This will run the [./k3s-servers.yml](./k3s-servers.yml) playbook and execute
 its roles.
+
+## After successful k3s installation
+
+To access our Kubernetes cluster from our host machine to work on it via
+flux and such we need to manually copy a k3s config from one of our server nodes to our host machine.
+Then we need to install `kubectl` on our host machine and optionally `kubectx` if we're already
+managing other Kubernetes instances.
+Then we replace the localhost address inside of the config with the IP of our load balancer.
+Finally we'll need to set the KUBECONFIG variable.
+
+```sh
+mkdir ~/.kube/
+scp k3s-server00:/etc/rancher/k3s/k3s.yaml ~/.kube/config
+chown $USER ~/.kube/config
+sed -i "s/127.0.0.1/192.168.20.22/" ~/.kube/config
+export KUBECONFIG=~/.kube/config
+```
+
+Install flux and continue in the flux repository.
