+#### Run pod sandbox with runtime handler
+
+Runtime handler requires runtime support. The following example shows running a pod sandbox with `runsc` hanlder on containerd runtime.
+
+```sh
+$ cat pod-config.json
+{
+    "metadata": {
+        "name": "nginx-runsc-sandbox",
+        "namespace": "default",
+        "attempt": 1,

+    },
+    "logDirectory": "/tmp",
+    "linux": {
+    }
+}
+
+$ crictl runp --runtime=runsc pod-config.json
