+# How to use Kubeinvaders on Minikube
+
+## Prerequisites
+
+- [Minikube](https://github.com/kubernetes/minikube)
+- [kubectl](https://kubernetes.io/docs/tasks/tools/)
+- [Helm](https://helm.sh/)
+- [Virtualization Software compatible with Minikube](https://minikube.sigs.k8s.io/docs/drivers/) (Parallels, VirtualBox, Hyperkit ecc). 
+
+## What we are going to install in our cluster
+
+- Kubeinvasers 1.9.6
+- Ingress addons for Minikube
+- x1 Deployment, x1 ReplicaSet, x10 nginx pods in namesapce **ns-1**
+
+## Walkthrough
+
+### Setup your Minikube cluster
+
+```make init-cluster```
+
+If no hypervisor is specified within the Makefile, the default will be parallels. Check this [link](https://minikube.sigs.k8s.io/docs/drivers/) for a complete list of Minikube-compatible drivers
+Within the makefile, you can specify other configurations as well:
+
+- Number of nodes
+- RAM
+- CPU
+- Kubernetes version
+
+
+### Setup Kubeinvaders, Ingress addons and Nginx deployment
+
+```make setup-cluster```
+
+### How to reach the applications within the cluster
+
+The two applications can be accessed at the following paths:
+
+- kubeinvaders.local
+- nginx.local
+
+However, to reach them, you need to add these two entries to the /etc/hosts file, associating these DNS names with the output obtained from the "minikube ip" command.
+
+Run 
+
+```minikube ip```
+
+and add the following entries to the /etc/hosts file:
+
+```
+<your_minikube_ip> kubeinvaders.local
+<your_minikube_ip> nginx.local
+```
+
+More about minikube ip command [here](https://minikube.sigs.k8s.io/docs/commands/ip/)
+
+Now you can visit the kubeinvaders.local page and have fun!
