 # Native k8s integration
 
 After following steps below, you will be able to capture traffic inside k8s like this:
+
 ```
-./gor --input-raw k8s://namespace/deployment/app:80 --output-http http://replay.com
+gor --input-raw k8s://namespace/deployment/app:80 --output-http http://replay.com
 ```
 
 GoReplay will running as a daemonset (e.g. on each phisical k8s node. 
 It will also require giving required permission to have read access to K8s APIs, so it can dynamically filter traffic for a specific pods.
 
-1. Create a namespace
+Supported format for filtering required pods:
+
+```
+k8s://[namespace/]pod/[pod_name] - k8s://default/pod/nginx-7848d4b86f-5nxz8
+k8s://[namespace/]deployment/[deployment_name] - k8s://default/deployment/nginx
