+### Distributed Load Testing  
+You can run cassowary in a distributed way if you need to scale up the load testing on more than one machine. Simplest way to do that is having access to a Kubernetes cluster. Use the batch type in Kubernetes and in the *spec.paralellism* key you can specify how many instances of cassowary you want to run simultaneously:
+
+```yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+  name: cassowary
+spec:
+  parallelism: 10
+  template:
+    spec:
+      containers:
+      - command: ["cassowary", "run", "-u", "http://my-microservice.com:8000", "-c", "1", "-n", "10"]
+        image: rogerw/cassowary:v0.14.0
+        name: cassowary
+      restartPolicy: Never
+```
+
+Just apply this yaml like so:
+
+```bash
+$ kubectl apply -f cassowary.yaml
+```
+
