+# Resilient Edge Toolstack "RET" Upgrader
+
+## Usage
+
+There are four environment variables to set in order for this to work:
+
+- `UPGRADE_TALOS` - Set to "true" if you want to upgrade Talos
+- `TALOS_VERSION` - The version of Talos you want to upgrade to
+- `UPGRADE_KUBERNETES` - Set to "true" if you want to upgrade Kubernetes
+- `KUBERNETES_VERSION` - The version of Kubernetes you want to upgrade to
+
+> :bulb: The versions of Talos and Kubernetes must be compatible with each other. Check the [Talos release notes](https://github.com/siderolabs/talos/releases)
+
+> :bulb: The version that will be upgraded to cannot be guarenteed to be the version that will be installed. The latest version that is available from the tool will be installed.
+
+
+Example:
+
+``` yaml
+          - name: UPGRADE_TALOS #Select if you want to upgrade Talos
+            value: "true"
+          - name: TALOS_VERSION #Select the version of Talos you want to upgrade to
+            value: "v1.4.8"
+          - name: UPGRADE_KUBERNETES #Select if you want to upgrade Kubernetes
+            value: "true"
+          - name: KUBERNETES_VERSION #Select the version of Kubernetes you want to upgrade to
+            value: "v1.27.4"
