+My script to update my kubernetes cluster at home.
+
+I typed a bit on the `notes.md` file, but that was mostly for myself.
+
+## How to use
+
+Modify the `inventory.yaml` file with:
+- Your desired hostnames
+- Your user/password
+- The desired kubeadm version. 
+
+Finally execute teh `run.sh` file.
+
+## Requirements:
+
+- **Remote** user with access to sudo
+- Only intended for Debian based devices (arm/x64)
+- DNS name from the hosts in the inventory must match the name of the node when using `kubectl get nodes` command.
+- Host/Client that will execute this Ansible script requires to have `kubectl` configured to target the desired kubernetes cluster.
+- Host/Client requires the `kubernetes` Python library installed [0a] and the kubernetes Ansible plugin [0b].
+
+
+[0a] Python Kubernetes package
+On Arch linux I had to use `pacman -S python-kubernetes`, you might get away with murder using the `pip3 install kubernetes` command. IDK
