+# Older Versions (containerd 1.1)
+
+This document describes how to install and run the `gvisor-containerd-shim`
+using the untrusted workload CRI extension. This requires `containerd` 1.1 or
+later.
+
+*Note: The untrusted workload CRI extension is deprecated by containerd and
+`gvisor-containerd-shim` is maintained on a best-effort basis. If you are using
+containerd 1.2+, please see the
+[containerd 1.2+ documentation](./quick_start.md) and use
+`containerd-shim-runsc-v1`.*
+
+## Requirements
+
+-   **runsc** and **gvisor-containerd-shim**: See the
+    [installation guide](/docs/user_guide/install/).
+-   **containerd**: See the [containerd website](https://containerd.io/) for
+    information on how to install containerd.
+
+## Configure containerd
+
+Create the configuration for the gvisor shim in
+`/etc/containerd/gvisor-containerd-shim.toml`:
+
+```shell
+cat <<EOF | sudo tee /etc/containerd/gvisor-containerd-shim.toml
+# This is the path to the default runc containerd-shim.
+runc_shim = "/usr/local/bin/containerd-shim"
+EOF
+```
+
+Update `/etc/containerd/config.toml`. Be sure to update the path to
+`gvisor-containerd-shim` and `runsc` if necessary:
+
+```shell
+cat <<EOF | sudo tee /etc/containerd/config.toml
+disabled_plugins = ["restart"]
+[plugins.linux]
+  shim = "/usr/local/bin/gvisor-containerd-shim"
+  shim_debug = true
+[plugins.cri.containerd.untrusted_workload_runtime]
+  runtime_type = "io.containerd.runtime.v1.linux"
+  runtime_engine = "/usr/local/bin/runsc"
+  runtime_root = "/run/containerd/runsc"
+EOF
+```
+
+Restart `containerd`:
+
+```shell
+sudo systemctl restart containerd
+```
+
+## Usage
+
+You can run containers in gVisor via containerd's CRI.
+
+### Install crictl
+
+Download and install the `crictl` binary:
+
+```shell
+{
+wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.13.0/crictl-v1.13.0-linux-amd64.tar.gz
+tar xf crictl-v1.13.0-linux-amd64.tar.gz
+sudo mv crictl /usr/local/bin
+}
+```
+
+Write the `crictl` configuration file:
+
+```shell
+cat <<EOF | sudo tee /etc/crictl.yaml
+runtime-endpoint: unix:///run/containerd/containerd.sock
+EOF
+```
+
+### Create the nginx Sandbox in gVisor
+
+Pull the nginx image:
+
+```shell
+sudo crictl pull nginx
+```
+
+Create the sandbox creation request:
+
+```shell
+cat <<EOF | tee sandbox.json
+{
+    "metadata": {
+        "name": "nginx-sandbox",
+        "namespace": "default",
+        "attempt": 1,
+        "uid": "hdishd83djaidwnduwk28bcsb"
+    },
+    "annotations": {
+      "io.kubernetes.cri.untrusted-workload": "true"
+    },
+    "linux": {
+    },
+    "log_directory": "/tmp"
+}
+EOF
+```
+
+Create the pod in gVisor:
+
+```shell
+SANDBOX_ID=$(sudo crictl runp sandbox.json)
+```
+
+### Run the nginx Container in the Sandbox
+
+Create the nginx container creation request:
+
+```shell
+cat <<EOF | tee container.json
+{
+  "metadata": {
+      "name": "nginx"
+    },
+  "image":{
+      "image": "nginx"
+    },
+  "log_path":"nginx.0.log",
+  "linux": {
+  }
+}
+EOF
+```
+
+Create the nginx container:
+
+```shell
+CONTAINER_ID=$(sudo crictl create ${SANDBOX_ID} container.json sandbox.json)
+```
+
+Start the nginx container:
+
+```shell
+sudo crictl start ${CONTAINER_ID}
+```
+
+### Validate the container
+
+Inspect the created pod:
+
+```shell
+sudo crictl inspectp ${SANDBOX_ID}
+```
+
+Inspect the nginx container:
+
+```shell
+sudo crictl inspect ${CONTAINER_ID}
+```
+
+Verify that nginx is running in gVisor:
+
+```shell
+sudo crictl exec ${CONTAINER_ID} dmesg | grep -i gvisor
+```
