 We will be using Selenium Grid Hub to make our Selenium install scalable via a master/worker model. The Selenium Hub is the master, and the Selenium Nodes are the workers(not to be confused with Kubernetes nodes). We only need one hub, but we're using a replication controller to ensure that the hub is always running:
 
 ```console
-kubectl create --filename=examples/selenium/selenium-hub-rc.yaml
+kubectl create --filename=staging/selenium/selenium-hub-deployment.yaml
 ```
 
 The Selenium Nodes will need to know how to get to the Hub, let's create a service for the nodes to connect to.
 
 ```console
-kubectl create --filename=examples/selenium/selenium-hub-svc.yaml
+kubectl create --filename=staging/selenium/selenium-hub-svc.yaml
 ```
 
 ### Verify Selenium Hub Deployment

 If you are using Google Container Engine, you can expose your hub via the internet. This is a bad idea for many reasons, but you can do it as follows:
 
 ```console
-kubectl expose rc selenium-hub --name=selenium-hub-external --labels="app=selenium-hub,external=true" --type=LoadBalancer
+kubectl expose deployment selenium-hub --name=selenium-hub-external --labels="app=selenium-hub,external=true" --type=LoadBalancer
 ```
 
 Then wait a few minutes, eventually your new `selenium-hub-external` service will be assigned a load balanced IP from gcloud. Once `kubectl get svc selenium-hub-external` shows two IPs, run this snippet.
