+# Adding and Removing Nodes
+
+Typical production clusters are hosted across multiple data centers and cloud
+environments, enabling them to leverage geographical distribution for improved
+availability and resilience.
+
+This tutorial simplifies the concept by creating a cluster within a controlled
+environment using two Multipass VMs. The approach here allows us to focus on
+the foundational aspects of clustering using Canonical Kubernetes without the
+complexities of a full-scale, production setup.
+
+## Before starting
+
+In this article, "**control plane**" refers to the Multipass VM that operates the control plane, while "**worker**" denotes the Multipass VM running the worker node.
+
+## What you will need
+
+- Multipass (See [Multipass Installation][Multipass Installation])
+
+### 1. Create both VMs
+
+The first step is creating the VMs.
+
+```sh
+multipass launch 22.04 --name control-plane
+```
+
+```sh
+multipass launch 22.04 --name worker
+```
+
+This step can take a few minutes as Multipass creates the new virtual machines. It's normal and expected.
+
+Install Canonical Kubernetes on both VMs with the following command:
+
+```sh
+sudo snap install --classic --edge k8s
+```
+
+### 2. Bootstrap your control plane node
+
+Bootstrap the control plane node:
+
+```sh
+sudo k8s bootstrap
+```
+
+Then, enable two components necessary for nodes' communication.
+
+```sh
+sudo k8s enable dns
+sudo k8s enable network
+```
+
+Canonical Kubernetes allows you to create two types of nodes: control plane and
+worker nodes. In this example, we're creating a worker node.
+
+Create the token for the worker node to join the cluster.
+
+```sh
+sudo k8s add-node worker --worker
+```
+
+A base64 token will be printed to your terminal. Keep it handy as you will need it for the next step.
+
+> **Note**: It's advisable to name the new node after the hostname of the
+> worker node (in this case, the VM's hostname is worker).
+
+### 3. Join the cluster on the worker node
+
+To join the worker node to the cluster, run:
+
+```sh
+sudo k8s join-cluster <token>
+```
+
+After a few seconds, you should see: `Joined the cluster.`
+
+### 4. View the status of your cluster
+
+To see what we've accomplished in this tutorial:
+
+If you created a control plane node, check that it joined successfully:
+
+```sh
+sudo k8s status
+```
+
+If you created a worker node, verify with this command:
+
+```sh
+sudo k8s kubectl get nodes
+```
+
+You should see that you've successfully added a worker or control plane node to
+your cluster.
+
+Congratulations!
+
+### 4. Delete the VMs (Optional)
+
+To delete the VMs from your system, two commands are needed:
+
+```sh
+multipass remove control-plane
+multipass remove worker
+multipass purge
+```
