+### Updating from v0.6.0
+
+#### Cluster update steps
+
+> **NOTE:** Updating multiple Lokomotive versions at a time is not supported. If your cluster is running a
+> version older than `v0.6.0`, update to `v0.6.0` first and only then proceed with the update to `v0.6.1`.
+
+Please perform the following manual steps in your cluster configuration directory.
+
+1. Download the release bundle.
+
+  ```bash
+  curl -LO https://github.com/kinvolk/lokomotive/archive/v0.6.1.tar.gz
+  tar -xvzf v0.6.1.tar.gz
+  ```
+
+2. Update control plane.
+
+  ```bash
+  lokoctl cluster apply --skip-components -v
+  ```
+
+  > **NOTE:** If the update process gets interrupted, rerun above command.
+
+  The update process typically takes about 10 minutes.
+  After the update, running `lokoctl health` should result in an output similar to the following:
+
+  ```bash
+  Node                     Ready    Reason          Message
+
+  lokomotive-controller-0  True     KubeletReady    kubelet is posting ready status
+  lokomotive-1-worker-0    True     KubeletReady    kubelet is posting ready status
+  lokomotive-1-worker-1    True     KubeletReady    kubelet is posting ready status
+  lokomotive-1-worker-2    True     KubeletReady    kubelet is posting ready status
+  Name      Status    Message              Error
+
+  etcd-0    True      {"health":"true"}
+  ```
+
+3. Run update script
+
+  ```bash
+  ./lokomotive-0.6.0/scripts/update/0.6-0.1/update.sh
+  ```
+
