+# Customizing the Lima instance for varying workloads
+
+You can customize Lima instance, using YAML and `yq`.
+
+#### Procedure
+
+- To create a new instance:
+
+  ```shell-session
+  $ limactl create <instance>
+  ```
+
+- To edit an existing instance:
+
+  ```shell-session
+  $ limactl edit <instance>
+  ```
+
+Some of the things you can edit:
+
+- Change the number of CPUs, the memory, and the disk size
+- Change the operating system (the Linux distribution)
+- Modify the cluster setup (the Kubernetes distribution)
+- Run **both** of container workloads and Kubernetes workloads
+
+### Containers
+
+You can install a container engine, in addition to the existing runtime.
+
+For instance you can install [Podman Engine](https://github.com/containers/podman),
+or you can install [Docker Engine](https://github.com/docker/docker).
+After that you can port forward the socket, to the host `Dir`.
+
+- `/var/run/docker.sock`
+- `/run/podman/podman.sock`
+
+```bash
+export DOCKER_HOST="unix://{{.Dir}}/sock/docker.sock"
+```
+
+### Kubernetes
+
+You can install Kubernetes, on top of the existing container engine.
+
+For instance you can use [CRI-O](https://github.com/cri-o/cri-o) for Podman,
+or [CRI-Dockerd](https://github.com/Mirantis/cri-dockerd) for Docker.
+After that you can copy the `kubeconfig.yaml` file, to the host `Dir`.
+
+- `/etc/rancher/k3s/k3s.yaml`
+- `/etc/kubernetes/admin.conf`
+
+```bash
+export KUBECONFIG="{{.Dir}}/copied-from-guest/kubeconfig.yaml"
+```
