Keep and write in html is pain, so I'm rendering md as html.

+By default [K3S](https://k3s.io/) comes only with
+[local-path](https://github.com/rancher/local-path-provisioner) storage
+class, and if you are running with more than one node in your cluster
+you may want to use a more \"distributed\" solution. For may case I
+opted for NFS.
+
+To check the current storage class you can run:
+
+``` bash
+k3s kubectl get storageclasses
+```
+
+And it will print something like:
+
+    NAME                   PROVISIONER                                     RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
+    local-path (default)   rancher.io/local-path                           Delete          WaitForFirstConsumer   false                  154d
+
+To start adding First you need to install
+[helm](https://github.com/helm/helm) on your server. To do so you may
+run:
+
+``` bash
+curl -sSL https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash
+```
+
+**Be careful when running scripts directly into bash always check the
+source** **Sometimes is also recommended to do not pipe directly to
+bash**
+
+Once it is installed we need to add the [NFS storage
+classes](https://kubernetes.io/docs/concepts/storage/storage-classes/#nfs).
+It has two providers, I have chose [NFS Subdir External
+Provisioner](https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner).
+
+Add the helm repo
+
+``` bash
+helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
+```
+
+Then we need to actually install the provider
+
+``` bash
+helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \
+    --set nfs.server=x.x.x.x \
+    --set nfs.path=/exported/path
+```
+
+Set the `nfs.server` and `nfs.path` accordingly with your setup.
+
+After that if we run `k3s kubectl get storageclasses` it will now print
+another NFS provider:
+
+    NAME                   PROVISIONER                                     RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
+    local-path (default)   rancher.io/local-path                           Delete          WaitForFirstConsumer   false                  154d
+    nfs-client             cluster.local/nfs-subdir-external-provisioner   Delete          Immediate              true                   76m
