+# Kubernetes Cluster Setup
+
+This README guides you through the process of setting up a Kubernetes cluster with vms using Vagrant and Ansible. Ensure that you have all necessary dependencies installed, including Ansible, Vagrant, and any SSH tools needed.
+
+## Steps to Follow
+
+1. First, change to the `kubernetes-cluster` directory
+2. Move your ssh public key into `kubernetes-cluster/ubuntu/vagrant/id_rsa.pub`
+3. Start the vm deployment with `vagrant up`
+4. Change, to the `ansible_playbooks` folder
+5. Optional: Sometimes you have to specify the ansible config
+    ```shell
+    export ANSIBLE_CONFIG=./ansible.cfg
+    ```
+6. Run `ansible-playbook setup.yaml` to setup cluster
+
+> The first time the manifests are automatically deployed after commissioning, the distribution of the pods may not be uniform.
+
+## Additional Notes
+Ensure that Ansible is properly installed and configured on your system.
+Verify that the SSH key has the correct permissions and is recognized by your system.
+If you encounter any issues, consult the official Kubernetes and Ansible documentation for troubleshooting steps.
+Conclusion
+Following these steps should successfully set up a Kubernetes cluster using Ansible. For more detailed instructions or advanced configurations, refer to the Kubernetes and Ansible official documentation.
